I was worried at the start that it was going to be just a Bosch advert however the second half was very interesting - never thought working on a hybrid was so dangerous!

Thanks for this one, Edd! My car is an '07 Honda Civic Hybrid. For anyone interested, its high-voltage isolation scheme requires removal of the rear seat back, then releasing a little access panel to reveal the switch, and then flipping said switch to the isolated position. The battery pack itself is mounted within an insulated capsule in the boot on the other side of the non-hinged rear seat, well hidden behind the fuzzy panels. Pretty great safety design but it limits the length of boards one can stow for any DIY woodworking projects!
Awesome video as always Edd. *Safety tip for folks changing their wiper blades:* Keep hold of the wiper arm at all times, then when you've disconnected the wiper blade, _carefully lay it back down_ onto a clean cloth on the windscreen before reaching for the new wiper blade. It only takes a moment but it saves you a fortune every single time on avoiding a very expensive accident. I've seen so many people leave it up out of bad habit (even the most experienced mechanics) then proceed to accidentally knock the wiper arm, which snaps down and cracks the windscreen. Yes, most folks have windscreen cover on their insurance, but try explaining that little mistake to your service manager (aka significant other 😅) why their car now needs a new windscreen...
@@mazdamaniac4643 Edd was saying changing the wiper was "easy and safe"; well, I do agree with easy, but my previous windshield wants to veto "safe"...
@@AttilaAsztalos Ahh, no worries mate. I've had a few close calls myself with this and after seeing the results happen to the guy working next to me in the workshop, I was "Nope." and the cloth on the windscreen from then on.
This may have been commented before, tip when testing insulated gloves for cracks is to hold them front and back then open, instead of at the sides before flipping them to trap air. It creates more space inside the glove at the start and holds more air for leak check. Great video.
Edd, I work for a large telecom, where we use class 2 insulating gloves, as well as rubber mats. For a very short time, we switched to class 0, but found that that they had to be discarded at the end of their certification, whereas the class 2, that we've always used, can be returned for recertification. Prior to expiration, we order replacements, then return the old ones. We do the air test, but after the pull test, pulling the fingers apart while looking for the contrasting color to indicate any cracks or splits. then turn it inside out and repeat all that. Ours are black outside, red inside. Cheers!
I drive a Prius 2 a lot of years. The best car I ever have. Since the display limit of 299.999 km has reached, the actual km range must be more than 300.000 km. I like your instruction for a save working on the servicing of a hybrid car. Thanks
Jaguar wanted nearly £400 to service my 4 year old I-Pace. I looked at the job spec, it entailed changing the pollen filter, topping up the washer fluid and changing the brake fluid. Basically a rip off. The cabin filter I changed myself for £15, the washer fluid cost me £4.99 from Tesco for 5 litres, and the brake fluid change cost me £72 from my local garage. Total cost £91.99. With the £300 saving I'm going to Tenerife for a week!.
Another great video of Ed continuing his work to Inform and Educate a principle of the BBC which he may of watched when he was younger. Continue sharing your wisdom.
I always enjoy Edd's videos but of late they have been too few and far between. I wish they were more regular than they are and of course there are so many projects we would like to have updates on.
Bought my first hybrid, an 07 Prius, the beginning of this year and it’s been great. Had 201k miles when I bought it and 223k now with the only work needed was the coolant inverter pump went bad(1hr job + $100 part) and I just replaced the struts all around last week from being worn out. Otherwise it’s just been oil changes, filters, and tires. Even has original brake pads!
I do have a soft spot for Bosch because their only shareholder is a non-profit, charitable foundation. Instead of enriching shareholders and fund managers their profits go towards good causes. I like ZF for the same reason.
Ed, extraordinary and very entertaining video, like everything you generate for us. I've always followed you, and I appreciate your work. Thank you very much..!
I don't know what was better. The insightful and instructional video or "The Edd China's a million ways to get killed to death fatally comedy show". Thanks for the upload, Edd.
I build valve amps and repair valve radios as a hobby. Great fun. The one hand behind your back is par for the course as 1200v AC is often exposed inside the equipment. If you are very careful it is safe though I have been bitten in the past. Only by about 200v but that was scary enough.
Good advice. I do the valve thing too. I once accidentally brushed against the DC link of an industrial inverter. That's 3-phase mains, rectified (about 600V DC). It pulled a muscle in my wrist that ached for over a week - and that was a very lucky escape.
@Figment He's not a YTer, he's just on YT as well. Also, you should check his profile and social tab, he mentioned that they are taking a well deserved rest. It would be preferrable if he made it more clear but ohh well...
Hi, Mark! Yep, it's no different from shoeing a carthorse in the olden days; important to remember to fill its nosebag with oats before starting work lest Old Ned throws a wobbler and kicks your head off... 🤭
Seems extremely unlikely that the engine will randomly turn on if ignition is off. It’s not like Priuses are frequently turning on in the middle of the night. Disconnecting 12V is just good practice for certain jobs whether pure ICE or hybrid.
@@TheEquationSlayer I've replaced front brake pads and rotors on an early Prius about 5yrs ago and I was warned to disconnect the 12v battery, can't remember the reason but seemed like a good idea at the time and we had no problems, looks like we avoided being "killed to death fatally" which sounds rather nasty🙂
@@darylwalford8697 That's because the brake system will pressurise itself when you open the drivers door. Makes for quite a mess if one of the calipers is hanging off on the side and somebody opens the drivers door.
Hi Edd, As a trained HV mechanic and designer of an electric conversion kit for a specific vehicle, I'm having some trouble with your video. For servicing the engine and brakes it's absolutely not necessary to place the HV battery in a safe mode. Removing the key, and maybe disconnecting the 12Vdc battery will de-energize the contractors and therefor isolate the HV battery. When do you need to put the HV Battery in a safe condition: when working on HV components, cabling or working in close proximity to these parts. This last item might be a reason to disconnect the HV Batt during service, but in my opinion it's a bit overdoing it.
Hola Excelente. Video y explicación...la verdad como siempre lo que enseñas y siempre vas avanzando así lo moderno en lo que está el mercado automotriz..gracias... desde quilmes desde América del Sur. Saludos 🤗 🤗
A very interesting video which taught me a lot. Thank you for sharing the knowledge with us. I wonder how many "home mechanics" are likely to be caught out by the dangers highlighted in this video?
Back in the 70''s The one hand behind you was taught to TV engineers when working on old 25Kv eht screen colour tubes also to discharge the set via the mains plug with a 1k 5watt resister to discharge the set completely, I made an adapter for the TV plug to plug in to with the resister build in. But one day when picking up an old mono TV, screen to my chest, I forgot the plug adapter Left in my van and the tube discharged via the mains plug in my hand to my chest, I never forgot to use the adapter after that.
But an EV, with around 30 moving parts, has considerably less chance of requiring fixing than an ICE car with over 2000 moving parts....... What isn't there can't break or wear out.
I really learned something today, thanks Edd. Whilst my suspicion of the green credentials of electric and especially hybrid vehicles have been reinforced by this video; I believe that pure electric vehicles can now be driver/owner maintained, with the specialist stuff being left to the professional. Just like DIYers do now. Removing the 12v supply to disable the contactors would be enough for me, to do say a brake service. We just need that magic battery technology that weighs no more than a tank of petrol, charges in five minutes, is made from green, recyclable materials and lasts longer than the car itself! Or hydrogen fuel cells. Personal transport must continue. It's a basic human right!
carefull with that, the car might be trickle charging the 12V from the big pack as you were undoing it. which could mean that the 12V system was still powered. Double check that the 12V system is completely dead after disconnecting the battery before you trust that. Check the service manual for the minimal actions needed for your particular car to make it safe to work on.
Not so. The first service on my Kia eNiro cost me less than £90. Both guys at my local (village) garage have been on the HEVRA course, and are certified to work on electric vehicles.
Reminds me on working with trolleybuses, especially the huge capacitor bank. You can either wait until it discharges via the bleeder resistor, or, if impatient, place a screwdriver between the terminals. Before that, make sure to say farewell to your screwdriver.
Hi Edd, thanks for the very informative video which is timely because my friend just bought a new Hyundai Ioniq PHEV, we have well equipped workshop and normally service our own cars but the Ioniq will very likely be going to the dealer to be serviced especially since being "killed to death fatally" sounds particularly nasty.
I noticed the "spare" hand out of the way trick. Reliability of early computers was improved by not turning them off. Repairs could be made with the high voltage on using an unearthed soldering iron and your other hand in your pocket.
Would be wonderful if you also did "will it start" videos like Mustie1 or others... Was so much fun that you repaired and explained every step you did before... 🤗🤗 Love you Edd China
May I make an observation? Edd, you forgot to maintain the fan of the battery; it gets full of debris since it’s inside the cabin by the passenger side... I enjoy watching your films learn a lot thank you
Edd, you should have called the video "Will it kill you to death fatally?" And only 400v? Pffft! Try 25kv from an old CRT TV tripler. But yeah, the most dangerous part is the current. As little as 0.1 amps across the old ticker can kill you to death most fatally.
Quite interesting video about managing the danger of a missing check on an electrical circuit. I remember have changed an internal battery on a wireless Bosch sander and made a mistake while soldering poles, only 12 v but it hurts when I accidentally touch a pole with my tin welder. I should have done a course like Edd about safety on managing batteries first.😅 Nobody thinks can be harmful a disconnected battery until you accidentally touch it.
High voltage is dangerous but it is the high current (amps) which sets the car on fire or gives you terrible burns. This could happen with a ICE car and it's 12V battery to a smaller degree. Never underestimate the power available from a battery ! Good video Edd.
Great video Ed. These precautions are certainly neccessary but I can imagine a lot of DIYers will have the safety third attitude and will get out there and do their service with their Marigolds on. I didn't realise it was so dangerous so some good information. Not that I will have an electric car for a few years.
Hi Edd I'm really glad you're back however not only are there huge holes in the planet where the materials to manufacture the batteries come from they then have to be transported by diesel and fuel oil vehicles to the factories, the are then manufactured using electric produced by burning gas they then need transported to the huge car factories where once again the electricity is produced by burning gas, they then have to be transported to the dealers by yes you've guessed it vehicles burning diesel and then when they finally get to the customer they are then charged with electricity generated by burning gas or nuclear power stations!!!
Pete, you need to remember that the oil companies have also made huge holes in the ground for literally decades, mining for cobalt, which they use to remove sulphur during the refining process. The oil industry are the largest users of mined minerals on the planet. You also overlooked the bit where - after a while - older EV batteries can be 95% recycled, with most of the lithium and cobalt within them being returned to the manufacturing stream to be reused in new batteries. Can you show me a gallon of recycled petrol or diesel?
I did the electric hybrid 2 &3 course a couple of years ago but have forgotten most of it !!!, so its good to see videos like this to remind me, but i have serviced a few hybrid cars and i have never isolated the batteries !!!, i just remove the ignition key and take it out of range of the car.
Note DC is more dangerous as it tends to make you clamp on, unlike AC which throws you off. Of course in these cars you will have both. Accident damage will be a tricky area and have to be left to specialists?
Yet to be convinced these are environmentally an improvement on an economic 4-pot ICE. Once you factor in the impact of mining eg lithium, copper and iron ore - the impact of the power stations you use to charge it - and the high cost of replacing batteries after ~10 years of usage probably making most of them scrap... But have to start somewhere I suppose. Interesting insight!
Don’t forget to factor in the drilling of the oil, the shipping to a refinery, the energy to refine it, the shipping to the fuel station and the fact that when we bother to run the planet on renewable energy then the EV route makes a lot more sense. It’s definitely part of the answer.
Ed, loved your informative video as I knew I would :-), though as a bit of feedback the video editing needs a bit of work. I could do a better job which does not say much. :-) Your car videos are a spark of positively in the current scary world we live in. I always feel I’ve learnt something after watching them, and that feels good. Especially in a time when so many car programs on tv these days are just nonsense and provide little or no information of value. Thanks chap. Watching your video has turn my dark morning into a positive one. Still got to finish your book too (got distracted by life some time back). My son still talks about sitting in your chair at the book store and meeting you! Though I’m not expecting you to remember us. Thanks to my dad and you and still get joy from picking up a spanner and working on cars. Did the timing belt on my car this year and the other week I replaced my brake discs etc. Whenever I have a problem I think “What would Dad or Ed do?” So thanks for all the help you’ve given me, even if you’d didn’t realise it. 😊
Thanks for the video, found it very interesting. I suspect that most home servicing of electric/hybrid vehicles will just be done with just the 12 volt battery disconnected.
Dear Edd, i have a question - I feel that there is too little information on such things as battery life and costs of replacement batteries on the EV Car market. I have been told that there are even a couple of manufacturers on the EU Market that don't even offer replacement batteries and sometimes it isn't even worth replacing batteries due to the high costs. Also things such as recycling costs and environmental costs are either not clear or even worrying. Could you please clarify or even do an episode on such uncertainties?
Speaking of environment there seems to be little mention generally where the content for EV batteries comes from (mining) and where used batteries need to go (landfill). How friendly then are they?
Only a complete bell-end would put old EV batteries in landfill. They're worth a small fortune to the energy industry, plus they can be 95% recycled, with the lithium and cobalt being 90% recovered to be reused in new batteries. It has been illegal for years to place *any* type of battery waste into landfill in either the UK or Europe. If you need examples of what the energy industry does with old EV batteries, you could look up the huge Sports Stadium in Utrecht, Holland, powered by 200 old Nissan Leaf batteries, charged via solar. Or there's the big windfarm in South Wales, which uses 300 old BMW i3 batteries for energy storage. It's a good thing the future of energy doesn't rely on people who would just bury old batteries, isn't it?
Oh! Hi Edd! Missed you 😘 Having just bought a mild hybrid, this was very interesting and thought provoking! Like finding a friendly local garage that will look after it for me 🤔
Glad to see Mr Edd back on our UA-cam screens...interesting video! So I have a non EV related question to do with the very last few frames of the video if I may... When Edd topped up the engine oil, it was to the 'max' mark. I tend to do that too, oil to max to help cooling and make sure my engine has plenty of 'blood'. But just checking that filling to the 'max' mark is good practice? Obviously, too much oil is bad but to the 'max' is okay - yes?
Thanks, Ed. We are missing this sort of video for EVs. As an amateur mechanic and professional engineer for inverter and servo drives, this is what I want to see. As a hobby I build valve (vacuum tube) audio kit running at 500V DC and being told to work with ONE hand only is life-saving advice. I would urge caution over the term "low voltage" though. "Low voltage" is defined as greater than 50V and less than 1000V, so ALL of the vehicle is "low voltage" (See the definition: en.wikipedia.org/wiki/Low_voltage ). Below 50V is EXTRA low voltage (and safe). I'm not sure about the rest of the electrics eventually being 48V. Trucks and industrial control systems already run at 24VDC so why a different standard?
I was worried at the start that it was going to be just a Bosch advert however the second half was very interesting - never thought working on a hybrid was so dangerous!
It’s dangerous alright I’ve worked on one never wanna work on one again
II was a firefighter when the electric/ hybrid cars started hitting the roads. I got ahold of a video done by Toyota covering first responder safety during accident rescues. The bottom line is yes they can kill you of you come into contact with the high voltage components. There is supposed to be an automatic disconnect for the batteries after an accident however there are a number of failures with those. The recommendation was for first responders to wear "lineman's" safety gloves when using the jaws of life or a cutter incase the HV lines are cut into. Tere is a lot more in the course but yes they can be dangerous.
2022's best quote, " no one wants to be killed to death by a Prius"🤣🤣
NO one wants to drive or admit they own a prius....
Or drive one
Fatally!
"killed to death fatally"
Anyone driving a Prius is an uber driver until proven otherwise
What's happening with the Range Rover, it's been months since the last video.
Thanks for this one, Edd!
My car is an '07 Honda Civic Hybrid. For anyone interested, its high-voltage isolation scheme requires removal of the rear seat back, then releasing a little access panel to reveal the switch, and then flipping said switch to the isolated position. The battery pack itself is mounted within an insulated capsule in the boot on the other side of the non-hinged rear seat, well hidden behind the fuzzy panels. Pretty great safety design but it limits the length of boards one can stow for any DIY woodworking projects!
I remember when Prius came on market i work at Toyota that time. Blow in gloves and take away security switch was something i never forget.😃
Awesome video as always Edd.

Did they actually give you the full course? That could make for some awesome content that's different from what most other youtube creators can do!
If they did that, DIYers wouldn't pay to do the course
Imi are trying to license working on EVs.
The level 3 course is pretty poor
From looking at the special handling precautions shown, I'm thinking garage labor rates will probably double.
As will the number of inadequate mechanics.
Yep. Mechanics will have to do courses and purchase insulated tools, neither of which will be inexpensive
Not so. The first service on my Kia eNiro cost me less than £90. Both guys at my local (village) garage have been on the HEVRA course, and are certified to work on electric vehicles.

Edd, you should have called the video "Will it kill you to death fatally?" And only 400v? Pffft! Try 25kv from an old CRT TV tripler. But yeah, the most dangerous part is the current. As little as 0.1 amps across the old ticker can kill you to death most fatally.
Quite interesting video about managing the danger of a missing check on an electrical circuit. I remember have changed an internal battery on a wireless Bosch sander and made a mistake while soldering poles, only 12 v but it hurts when I accidentally touch a pole with my tin welder. I should have done a course like Edd about safety on managing batteries first.😅 Nobody thinks can be harmful a disconnected battery until you accidentally touch it.
Hi Ed, did EV1 a couple of weeks ago, learnt the new ways a car can kill you! I will be off to take EV2 shortly!
Nice to see you back
Welcome back good ot see you amazing show true legend never forgotten 🤠🤠♥️
High voltage is dangerous but it is the high current (amps) which sets the car on fire or gives you terrible burns. This could happen with a ICE car and it's 12V battery to a smaller degree. Never underestimate the power available from a battery ! Good video Edd.
thanks for remembering us. great video
gracias por acordarse de nosotros. gran video.
Great video Ed. These precautions are certainly neccessary but I can imagine a lot of DIYers will have the safety third attitude and will get out there and do their service with their Marigolds on. I didn't realise it was so dangerous so some good information. Not that I will have an electric car for a few years.
Hi edd. So happy for your return.
Hi Edd I'm really glad you're back however not only are there huge holes in the planet where the materials to manufacture the batteries come from they then have to be transported by diesel and fuel oil vehicles to the factories, the are then manufactured using electric produced by burning gas they then need transported to the huge car factories where once again the electricity is produced by burning gas, they then have to be transported to the dealers by yes you've guessed it vehicles burning diesel and then when they finally get to the customer they are then charged with electricity generated by burning gas or nuclear power stations!!!
Or they could power all the trains and trucks by electricity made by renewables and things would be a lot better and we would have a cleaner future.
Pete, you need to remember that the oil companies have also made huge holes in the ground for literally decades, mining for cobalt, which they use to remove sulphur during the refining process. The oil industry are the largest users of mined minerals on the planet. You also overlooked the bit where - after a while - older EV batteries can be 95% recycled, with most of the lithium and cobalt within them being returned to the manufacturing stream to be reused in new batteries. Can you show me a gallon of recycled petrol or diesel?
I'm going to the shop next week. Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Bosch, Boooossscchhhhhh.
I did the electric hybrid 2 &3 course a couple of years ago but have forgotten most of it !!!, so its good to see videos like this to remind me, but i have serviced a few hybrid cars and i have never isolated the batteries !!!, i just remove the ignition key and take it out of range of the car.
Note DC is more dangerous as it tends to make you clamp on, unlike AC which throws you off. Of course in these cars you will have both. Accident damage will be a tricky area and have to be left to specialists?
Yet to be convinced these are environmentally an improvement on an economic 4-pot ICE.
Once you factor in the impact of mining eg lithium, copper and iron ore - the impact of the power stations you use to charge it - and the high cost of replacing batteries after ~10 years of usage probably making most of them scrap...
But have to start somewhere I suppose. Interesting insight!
Don’t forget to factor in the drilling of the oil, the shipping to a refinery, the energy to refine it, the shipping to the fuel station and the fact that when we bother to run the planet on renewable energy then the EV route makes a lot more sense. It’s definitely part of the answer.
Good shout Ed, you are absolutely right
Message heard loud and clear and i absolutely agree with you, ban all hybrid and electric cars.
Especially Prius's
Yes missed you edd nice to see you back
Think Ill stick to ICE car, less hassle, and about half the price or more than an EV.
Missed you, great to see you today 😀
Greenhouse gasses...... good for your greenhouse ! A handy vid thanks.
Ed, loved your informative video as I knew I would :-), though as a bit of feedback the video editing needs a bit of work. I could do a better job which does not say much. :-)
Your car videos are a spark of positively in the current scary world we live in. I always feel I’ve learnt something after watching them, and that feels good. Especially in a time when so many car programs on tv these days are just nonsense and provide little or no information of value. Thanks chap. Watching your video has turn my dark morning into a positive one. Still got to finish your book too (got distracted by life some time back). My son still talks about sitting in your chair at the book store and meeting you! Though I’m not expecting you to remember us. Thanks to my dad and you and still get joy from picking up a spanner and working on cars. Did the timing belt on my car this year and the other week I replaced my brake discs etc. Whenever I have a problem I think “What would Dad or Ed do?” So thanks for all the help you’ve given me, even if you’d didn’t realise it. 😊
Glad you are enjoying the book and the show and great that it’s spurred you on to doing your own maintenance.
Everyone expect you do this kind of work.👍😎
Alas, the day of the shade tree mechanics is gone. Oh well I feel lucky to have been a child of the 50'. Thank you, take care and cheers!!
Thanks for this video Edd! 👍😁
Thanks Edd! Welcome back!
Thanks for the video, found it very interesting. I suspect that most home servicing of electric/hybrid vehicles will just be done with just the 12 volt battery disconnected.
And hopefully more people will know that isn’t the best way to do that. Let’s hope!
As expected, good concise practical demonstration. 👍🇬🇧
Always keen to see another video. This one was just as good as the usual. Nice work 👍
Just an fyi from a telecoms eng, 48v has a hell of a kick. But DC means you don’t get hooked up.
Dear Edd, i have a question - I feel that there is too little information on such things as battery life and costs of replacement batteries on the EV Car market. I have been told that there are even a couple of manufacturers on the EU Market that don't even offer replacement batteries and sometimes it isn't even worth replacing batteries due to the high costs. Also things such as recycling costs and environmental costs are either not clear or even worrying. Could you please clarify or even do an episode on such uncertainties?
Speaking of environment there seems to be little mention generally where the content for EV batteries comes from (mining) and where used batteries need to go (landfill). How friendly then are they?
Or the child labour digging that lithium or cobalt out of the ground.
Only a complete bell-end would put old EV batteries in landfill. They're worth a small fortune to the energy industry, plus they can be 95% recycled, with the lithium and cobalt being 90% recovered to be reused in new batteries. It has been illegal for years to place *any* type of battery waste into landfill in either the UK or Europe. If you need examples of what the energy industry does with old EV batteries, you could look up the huge Sports Stadium in Utrecht, Holland, powered by 200 old Nissan Leaf batteries, charged via solar. Or there's the big windfarm in South Wales, which uses 300 old BMW i3 batteries for energy storage. It's a good thing the future of energy doesn't rely on people who would just bury old batteries, isn't it?
Great video. Hope you can do the next level of the course and show us that too.
9:26 - Misspellings of both 'subscribe' and 'subscribed'. Missing the second 's' in each.
Just tryin' to help, keep on keepin' on Edd!
Oh! Hi Edd! Missed you 😘 Having just bought a mild hybrid, this was very interesting and thought provoking! Like finding a friendly local garage that will look after it for me 🤔
You probably have an auto sensing multimeter… you might want to mention flipping between AC and DC scales for simpler meters. Thanks for the vid.
Glad to see Mr Edd back on our UA-cam screens...interesting video!
So I have a non EV related question to do with the very last few frames of the video if I may...
When Edd topped up the engine oil, it was to the 'max' mark. I tend to do that too, oil to max to help cooling and make sure my engine has plenty of 'blood'.
But just checking that filling to the 'max' mark is good practice? Obviously, too much oil is bad but to the 'max' is okay - yes?
Thanks, Ed. We are missing this sort of video for EVs. As an amateur mechanic and professional engineer for inverter and servo drives, this is what I want to see. As a hobby I build valve (vacuum tube) audio kit running at 500V DC and being told to work with ONE hand only is life-saving advice.
I would urge caution over the term "low voltage" though. "Low voltage" is defined as greater than 50V and less than 1000V, so ALL of the vehicle is "low voltage" (See the definition: en.wikipedia.org/wiki/Low_voltage ). Below 50V is EXTRA low voltage (and safe).
I'm not sure about the rest of the electrics eventually being 48V. Trucks and industrial control systems already run at 24VDC so why a different standard?
I wouldn’t mind doing that course Edd.
Great to see you back! Was getting worried………
He obviously isn’t killed to death.
Brilliant 😎👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
