I wanted to test my starter relay today and watched a bunch of clips on YT. This one is the best I have seen. Simple, step by step from beginning to end, very methodical. A one time explanation and one time understanding.
Can’t thank you enough for taking the time to make these vids, walk viewers through in simple terms how to do all this! Truly a life saver as I try my best to fumble through trying to diagnose and fix my vehicle with only basic knowledge of mechanics 😂 I really appreciate you, Sir!!
Many, many thanks for your well made video on how to use meters to check electrical parts. I really appreciate that. You went even beyond ... for us to lose the fear of doing something wrong. Many regards from Florida
Good video bro! Saved me time. I used stranded copper speaker wire to wire it to my car battery. Super ghetto but i got it done. Relay is functional, and has continuity when live. I've also tested my motorcycle relay months ago before this video, but it was way more straight forward. the power and ground were obvious, this relay it wasn't. relays good, my starter motor isn't. Need a new one. rofl hardest part was when i realized.. (bulky jumper cables) aren't the best way to put power on it.. haha, so i swapped to speaker wire. worked will, i tied it on and it was functional. Keep up the great work! We appreciate it.
Thank you, nice and easy and thorough and complete. I was going to buy a relay for $50 not knowing if it was good or bad. But now I can test it and see if it is good or bad.
I actually searched for a non-working snowmobile electric starter and got this video ! I actually pulled out nearly the same relay from my sled's electric starter that wasn't working ! I just ordred the relay hopefully it will work and turn over !
With Denso 4 prong relays the copper prongs are the ones that connect to components, or load (terminals 87 & 30)& usually they're a little larger as well, so the ones you connect to power will be the smaller, less coppery colored ones..#s 85&86
Thank you so much for your easy to follow and understand video as I’m having just such a problem on my 1996 FourWinds, Class A, motorhome. I’m hoping to learn some basics before a mechanic starts replacing one part after another as I’m a senior citizen female. I believe I’ve an honest mechanic but I feel better having some knowledge of how things work even though I’m not comfortable doing any such repairs. I did opt to pick up (2) new batteries as the deep cycle marine battery was 12 years old and wasn’t charging on a trickle charger. The engine battery was a 5 year battery with only 7 months left on it’s warranty and I don’t want to get stuck somewhere along my travels. So those have been installed but still no turn over. I asked about the possibility of the ignition switch but after he attempted several tries of starting and removing the doghouse cover he next went to the starter relay. Just waiting for part to be ordered in the morning and installed. But before he installs the new part I’ll ask him to test the old one.
Thx. Great vid. I was starting to work on my 2010 Sequoia 5.7L and that will take me days. So I found your vid and did what you said. My starter relay is bad. You saved me $200+ and days of labor. Thx. again.
Relays usually have markings on top denoting pin functions. A "ww" represents a resistive load - that of the relay's coil. A "NO" is normally open contacts...a "NC" being normally closed. Hope this helps.
Great video mate, I do lots of mechanical work, but know very little about electronics, this may prove to be an invaluable piece of info for me. Thank you!
When checking for continuity on the horizontal prongs, as a final test, can you also check them with either a test light or the multi meter set at 12 volts?
I just wanna say thank u so much ,,, boom my realay was fucked ,,, wouldn’t av none this if it wasn’t for your brilliant explanation of testing ,,, thank u 🙏 Adam
Great hack! I'm curious...could I also test for a bad relay by switching a known good relay for the suspected bad one? My 1997 Ford Explorer has 3 of these relays and I know for sure that two of them are working.
So when this relay goes out is it permanently shot or maybe sometimes works sometimes don't ?😂. My car it's random no start but🤔 I do hear a single click from I think the ignition switch Great video, and much appreciated .🙂
Thanks for the video. If you had an intermittent no crank fault and carried out this check, would it only show a fault some of the time? My 2008 Mercedes CLK fails to send power to the starter motor occasionally and I think it's either this relay or the electronic ignition switch but because the fault comes and goes as it pleases I'm not sure how to test. Any ideas?
Overall good video, however, towards the end, you zoomed into the prongs on the relay itself, and you should have zoomed in on the tester to show what will happen to the display when you have them touching the correct ends... what does the LCD do? Overall, good, but that could have really solidified the explanation.
This shows when it is working, but if it is going bad, the relay would be giving continuity but be jumping in ohms up and down correct? Therefore in need to be replaced
Thank you very much for the video! I tested the ignition coil and starter relay and both show (sound) continuity but neither click. Could this be because they are both stuck in the closed position?
I have a 1996 dodge ram. And it starts most of the time, but there's sometimes that won't do anything. We got a switch adapted to it that would get it started. Any idea what it can be. Thanks.
Hi, I have a problem with my Honda CRV 2007, 4 cyl. When I started the car looks like my battery is low Volts or my starter is heavy to turn. I change the battery and starter but still doing the same, the motor start but on winter season is more slow to start and some times I run out the battery power. Thanks for you cooperation.
sir.. you should not ever use the Ohmmeter function on an energized circuit. it can 1.) Damage your DMM PCB circuits 2.) Provide inaccurate or irregular readings. The multimeter checks for continuity by applying 3v to the circuit at a very low amperage, and checking for that 3v signal to return to the DMM through the COM port lead. Checking for continuity in a 12v circuit should always be done with the relay disconnected from all power sources. If you want to do it energized, you use the DC Volts setting on the DMM and check for 12v to be present at all pins expected to be energized when the Relay coil is energized...
When I pulled my toyota corolla starter relay out, I saw something creamy sticked to the contacts of what seemed to be grease? Where that peanut butter could come from? Even the base of the relay has the same things and contacts are almost covered with that. Will I have to purchase the whole box where this relay and fuses live? Can I wash it down with alcohol? Is the sunny Florida also melting the electronic components of our cars, besides al the rest of the plastic components? My car with a 12.7V battery just gives me a "click" but it does not crank or start when I want but much later ...

Thank you for taking you’re time on this video
congratulations on the fine job you do explaining things.

Thanks for step by step making it simple while others go fast in explaining and we ended up with confused ❤👍
Love that you took the time to be detailed and show step by step. Keep up the great videos. Used your channel for multiple things now.

Thanks a million for showing the trim removal! So many other vides show the relay with the trim already removed.

What symptoms was it showing ?
Very nice video. Great explanation and very precise details. Thank you so much. 👊🏽

One word ultimate explanation
👏 Thank you for this very helpful video.
Thanks man for making a good video 👍 no ramble ... you got right to the point ...I fixed my issue within 10 mins I was back rolling again
Glad it helped
Can this affect modern 2017 till date car also?
Good video. Not too long and to the point. 👍
You are really good at explaining. Well done.
Wow this was so explainable and easy to understand, Thank you.
As always, a thorough, very well-organized, very well presented tutorial.
I
The best video for the problem
Dude - this was a great video. Yes, have the problem you outlined and I feel confident I know how to do the test.
Thanks for the info. Its a great help for me as novice in the Automotive.
It enhances my knowledge on this field of industry.
Excellent!! How do you check using the battery?
Thank you!
👍 GREAT , THANKS, NEED TO BUY THE TOOLS, TRIM REMOVER & 12 VOLTS DEVICE .
What if it cranks on a push start but it's not your battery or starter ? Your explanations are nicely detailed btw.
Check the fuel pump/lines, spark plugs and ignition. Cars need combustion to operate and most times you’ll have a clogged fuel pump
Thank you for the useful video.
Thanks for the information. I will check it out now.
Nice job my friend!
When checking for continuity on the horizontal prongs, as a final test, can you also check them with either a test light or the multi meter set at 12 volts?
You know how to teach and make a video. Great A+++
Nice work man 👍🏿😘
Nice concise presentation. Thanks.
Glad it was helpful!

That's what I call a PERFECT VIDEO.
Great video !!!
Life saver man this fixed my problem. I replaced my battery for nothing but at least its new now lol
10/10 video! Very well done!
Very useful video. Like!!
Well done mate good explanation.
Excellent explanation, I learned a lot. Thanks you so much.

Ah, a nerd. Thank you very much for this video
Thank you. Going to check started relay on my 1981 BMW R80/GS.
Thank you so much...🙏
thank you brother
Great job indeed thanks a lot 🛠
This shows when it is working, but if it is going bad, the relay would be giving continuity but be jumping in ohms up and down correct? Therefore in need to be replaced
smart presentation
Video Start 5:58 thanks
Learn alot thanks for the video
Thank you
Nice tutorial sir...
Thanks so much!
Great job , thank you......way to go
Very informative
I agree with the guys very good video. Thanks alot
Will a bad relay cause a single click?
Yes sir
I needed to know that
@Longztx they just fix mine relay took off check engine light off
@@Longztx yes it will
Thank you all for that information 🙏
do i have to disconnect the battery to remove the starter relay? is it required?
Another great job with the video!
Thank you very much for the video! I tested the ignition coil and starter relay and both show (sound) continuity but neither click. Could this be because they are both stuck in the closed position?
Keeep rocking,,,
Excellent
Great video
and if it is a normally closed relay contact you blow your power supply... or at least the fuse in the ps if it has one.
Thanks A lot for the info, did it and my mdx started right up. This was Supremely helpful
Thanks
I have a 1996 dodge ram. And it starts most of the time, but there's sometimes that won't do anything. We got a switch adapted to it that would get it started. Any idea what it can be. Thanks.
Got this clicking starter overnight without earlier warning..new battery now..still same thing..naybe contacts to solenoid?
Most switches will also have a small diagram on them to show what you need to know.
Very helpfull god bless
Will it crank sometimes ?
So if the relay is bad the vehicle won't start? Does a qx56 have a relay switch?
Will a relay stick close so that it drains the battery I’ve got no power to my fuel pump brand new I had power when I put it in
Excellent video!!! Can you write the tools you use in this video?? Please!! Thank you for this video!!
He listed most of the tools in the video description but not the battery pack ( as of 2022-09-15).
Tank you
Hi, I have a problem with my Honda CRV 2007, 4 cyl. When I started the car looks like my battery is low Volts or my starter is heavy to turn. I change the battery and starter but still doing the same, the motor start but on winter season is more slow to start and some times I run out the battery power. Thanks for you cooperation.
So at the multitester is it using am which the red color cable insert?
Since it is for the starter would it be a solid state relay for high current draw ?
I get it now, thank you.
Nice video ..what is wrong if the engine check light does not come on when ignition is on?
Hi will a relay fault throw a warning light on the dash?
sir.. you should not ever use the Ohmmeter function on an energized circuit. it can 1.) Damage your DMM PCB circuits 2.) Provide inaccurate or irregular readings.
The multimeter checks for continuity by applying 3v to the circuit at a very low amperage, and checking for that 3v signal to return to the DMM through the COM port lead. Checking for continuity in a 12v circuit should always be done with the relay disconnected from all power sources.
If you want to do it energized, you use the DC Volts setting on the DMM and check for 12v to be present at all pins expected to be energized when the Relay coil is energized...
Do you think 🤔 if doesn’t start at the first time is relay ?
When I pulled my toyota corolla starter relay out, I saw something creamy sticked to the contacts of what seemed to be grease? Where that peanut butter could come from? Even the base of the relay has the same things and contacts are almost covered with that. Will I have to purchase the whole box where this relay and fuses live? Can I wash it down with alcohol? Is the sunny Florida also melting the electronic components of our cars, besides al the rest of the plastic components? My car with a 12.7V battery just gives me a "click" but it does not crank or start when I want but much later ...
