My last seven years of work was as a production plant (food Cannery) Instrument Technician/Electrical Technician. I really enjoyed learning to troubleshoot and repair physical and code problems in the plant. There are many of the problems where your skills would be used to solve the problems. Also, as a Power Plant Technician. Power plants use many sensors to send signals to computer controlled, programmable system sontrollers Same as most roduction plants built now everything is computer controlled and automated to reduce manpower costs and operator induced errors.So, virtually every field is crying for people with your skills and are willing to compensate excellent technical problem solvers accordingly. Plus, you have excellent Resume enhancers in your online videos. You can troubleshoot from experience, intuition and the manufacturer's manuals. You are gold.
I was an Industrial Mechanic for over 35 years. I only worked on machinery not cars. Same rules apply for everything. Bad connectors, new parts that are bad, intermittent problems, computer errors. When a key piece of machinery fails it halts production. You may have over 100 people standing there looking over your shoulder waiting for you to get it running. (Including the VP) We always had tech support from the companies that made the equipment to assist. Knowing what parts to have on hand was also key. Much cheaper than 100+ people standing there for hours.. Lots of pressure.. lol
You are very right about the placement of that computer Ivan not a good place at all. My dad was a electrician and he always said heat is the number one enemy of electronics. Good fix
I think some of your most interesting videos are when you work things other than cars,It is not easy to on unfamiliar equipment, but you have good fundamentals and it is interesting to watch you figure it out.
Sweet diag as always Ivan. The fact that you're having fun doing something that you love is very apparent. Thanks for taking us along with you as you learn and grow.
Hi Ivan, The first thing I thought was why is an American company Zenith product on a Japanese engine. A quick search found Zenith electronics was bought out by South Korean company LG Electronics. Zenith made radios, tv's and stereos and started in the 1920's. As a young gear head I learned about Zenith updraft carburetors on the family 1953 Chris Craft powered by 339 cubic inch flat head six cylinder engines. My 1980 MGB used a Zenith/Stromberg carburetor from the factory and I quickly replaced it with a Weber carburetor. Great video as always. John
Keith tap test is a good one.Nice job Ivan, persistence paid off, but wow 3 hrs to get to original complaint, read 0 codes, then the tap test. Wow. Too bad about the epoxy sealed board, but the sticker shock of $2000! Holy crap!! That`s steep.
Industrial equipment parts are four times plus when compared to a lot of car and truck parts because of low volume specialty type of applications, he is very lucky he could find one period.
Wow. I was convinced there for a while the scissor lift was possessed! The good old tap test really brought out the gremlins, no scanner needed. Well done.
That was a nice case study. Also the tab test definitely brought out the ghost in the machine. When that engine took off it might me think of Detroit Diesel 2 strokes when an injector would stick and pull the rack wide open.
Just saw your cameo appearance on DiagnoseDan this morning. Classic UA-cam moment. Glad you kept your shirt on through this difficult diag. Thanks for giving us more great content!
Amazing example of sticking at it till the bitter end! Luckily, it wasn't my problem but friends of mine had a big concrete crushing rig over here in U.K. with similar run till warm then shutdown problems - diagnostics would've been so much easier with a scope - confused by the intermittent fault they suffered three days downtime before eventually finding several lengths of cable turned to oxides of copper internally so a very expensive shutdown was cured by £10 worth of new cable. Oh, yes - when started and back to work, one of the first lumps of concrete had a sharp rebar inclusion that split the belt end to end - not one of the best weeks.
Great job!! Kinda related, The old GM TBI systems if the ck. engine light burned out or someone removed it you couldn't read data from the ECM. The tap test worked great in that era of vehicles also!
Great job. Our biggest challenge with farm equipment is finding electric issues. The company just replaces the whole wire harness . And mice love wires. Wait till you get called to help on a John Deere combine issue 😅
Ivan if there is anyone in this business that give mechanics a good name and reputation it is YOU. You are the ultimate in diagnostics with a scientific approach (and you write it down) and you are willing to share your thoughts and opinions with all us subscribers. As always great diagnostics and fantastic explanation of problem and steps to solve it even down to a simple tappy tappy tap test ( always love AVE youtube channel tappy tappy tap when ever he goes there)
Jeez, two grand for a GM OBD-I ECM design from 30 years ago? Let's not kid ourselves, that's exactly what this is (only difference will be the calibration ROM for this particular engine)! Even seems to be a GM TBI design (speed density/MAP) adapted to electronic throttle and propane capability. I wonder if one of the ECU pins has ALDL live data? And according to my GM service manual, the codes are: 12 - system operational 14 - coolant temp high (low voltage, or short to ground) 33 - MAP high Oh yeah, most of those OBD-I ECMs were located in the passenger compartment, *not* the engine compartment. Maybe this one is more heat-tolerant but I kinda doubt it. More likely, it can take the heat just long enough for the warranty to expire!
But it's an ecu that controls dual fuel and has to adjust engine speed when using the lift! A little different than a regular obd1 gm computer which were junk back in the day! This one lasted a long time
Wow, that was neat Keith tap test!! Tap, tap, tap. Revvvvvv up lol. That's pricey part! But you had the proof in video!! That's solid one, nice one Ivan! Great ending!
Thanks for the video Ivan, It must feel kind of odd working on a scissor lift inside a garage that's not jammed against the building in freezing weather while it's raining. 😏
Lets put a heat/vibration sensitive device that is essential to the machines operation on top of the engine where it will recieve the most heat/vibration possibe. Lol. I would have moved it to a different location if possible. Probably not though as i am fairly sure the harnesses are not even close to long enough. Just a poopy design i suppose. Great diag as usual. I am enjoying the variety. Knowing i will not be completely in the dark should i need to poke around on one gives me a case of the feelsgoodman and for that i Thank you. 😀👍✌
Always check fuel tank for sabatoge on construction equipment especially here in NYC.. On cranes and JLG I got boards out found water and cracks on solder joints. I cut entire box open. Then reexpoxy to seal it . Hirschman LMI and A2B wireless modules cost $$$$$$$$$$. Excellent work thanks
Close call on the computer, but your method works. Learning how to read wiring diagrams is a critical skill, as is knowing when to use the tap test on components and when to apply the wiggle test on wiring connectors. Finally, always keep a can of full strength De-Oxit close at hand when on the job, and a soldering gun.
Its not the tech its the equipment. That is why some mechanics love industrial/heavy equipment, these companies need their equipment and will have to pay it all comes down to fixing it right and being reasonable with your charges i am sure there are some out there that try to bleed their customers dry in the heavy/commercial equipment service industry. I know that Stephen Cox is big into it down in Texas and he travels all around his state repairing everything from a Hay Bailer to a tractor.
That was hardcore! I am not sure about you, but I sweated as I watched... Interesting to learn about how to read codes on that. Hope to get smoother but still cool cases on your trip. Have a nice one! Thank you
probably where the connectors solder to the board, even the potting doesn't penetrate well enough to keep them from vibration fracturing. but GM OBD-1 TBI setups in that era were known for injector coil failures(low resistance) and cooking the ECM's inside also. hearing that one chatter the electronic throttle, I'd be leery of it going low resistance also. I never really dealt with the electronic throttles on them, but a coil is a coil :)
Great work Ivan, I love the Keith tap test, too bad that ECM was so expensive, the scissor lifts must be Super expensive that he was willing to put that kind of money into it
It is a Nissan. ancient? haha Actually it is A15 engine, looking into manual. Datsun stroker engine. And that is engine from 1970s, exhaust and intake manifold look original, they just put a TBI on top of it with the special ECU. Nice to see prehistoric engines run after more than 50 years. LOL
Peter Zoch the fuel system is a Zenith ZEEMS system, very outdated but still sold as new, why I don’t know, but potting is great until something goes bad, but I guess you know that one.
You are 100% right on the location of that computer, shake and bake lol :-D It would be good to get it away from the engine, but the cables to the sensors would have to be tied down to stop the wires jumping around like mad. Shame they potted it, but i would still keep it just in case someone finds a chemical to dissolve it. The keith test :-D
Back in the early days of satellite TV the receiver decoder was potted like that. People would use a heat gun to remove the potting from the security chip.
Ivan good job on the diagnosis...Sometimes I have found the coating is only on the back side of the board...if you can carefully slice along edge, the board may come out...then you can front flow the solder connections...I know it can be labor intensive, but at a $2000 , I would certainly attempt it...
A guarantee what a novel idea.. and Warranty. At a dealership lol i yet to hear about one . Also better chose wisely on a independent shop . Thanks for the videos
Ever hear the story about the ocean going ship with a failed engine ? Ship's engineer couldn't get it restarted, calls to tech help failed. Finally someone "knew" a guy. They get him to the ship with his tool bag. He looks at engine, removes hammer from tool bag, smacks engine...engine comes to life. His fee, $10,000. All because he knew what to smack with his hammer.
This is not a story about an ocean going ship etc. It's a made-up story that follows the well-worn, and well-known, plot of the "value of knowledge" allegory. And as written here, it's not even funny, just tired.
How annoying that the ECU is potted. I totally agree that it is most likely just a bad solder joint. Could have been a no-parts-required if the manufacturer didn't pot the ECU, but now the customer has to pay the price...
That is the same engine that was in my family's 1976 Datsun B210. Of course that car had a carburator. That engine ran great for the 12 years that the car was in my family until the frame rusted out and the car was no longer safe to drive. That car would even start in 15 below 0F temperatures during a Chicago winter.
Hey Jed, a Datsun B210 brings back some memories. They had their own flavor of rust. I remember the front calipers would rust/seize and like mad. Compared to the GM Vega, Ford Pinto and the Ford Maverick it was a no brainer. The B210 was the easy choice for a 1976 econo car.
@@roadshowerun1770 Oh yes that car had a lot of rust issues. It lived its life in Reading, Pennsylvania and then the Chicago suburbs. I learned how to drive in that car. It was a hand me down car from my mother to me and then to my younger brother. No real trouble with the brakes but plenty of body rust and holes in the floor that I sealed up with linoleum scraps and roofing cement. The front strut brace finally rusted off the frame under the bumper causing the entire strut and front wheel to be loose. The car was drivable but if it were to hit a large pothole the strut and wheel would have been pushed backwards into the body and possibly caused a crash. It was beyond repair as one can't weld rust to rust. It ran great though and it had the hottest heater of any car I've owned in the past 35 years. It could almost burn your accelerator foot even in below 0 weather.
Wow! The Genie lifts I have worked on have status lights on.the controller... makes for much quicker diagnosis. That blinkie-blinkie is reminiscent of 1984 Chrysler EFI...
Сталкивался с подобной ситуацией несколько раз. Компаунд сохнет и отрывает радиокомпоненты с платы. Самое трудное - подобрать растворитель. - растворить компаунд - вынуть и очистить плату - пропаять оторванные компаненты - перенести ECU в холодное место
Holy crapper! $2-LARGE for a magic box! Must be some expensive pixies in that one! Sprinkling gold and platinum dust around the magic components ... 😂 That's one you don't want to let the smoke out of!! Wild engine in that thing - sounds exactly like some other Japanese product's inline-4 motorcycles. Wow did that thing take off to the moon there when you tapped it! I was waiting for valve float, LOL! Sounded like it hit 14-grand! 😂🤣😂 That'll clear the carbon out! 😁
OMG, UA-cam is seriously pissing me off!!! I had a 3 paragraph comment written out, I post it, and the only thing to show was the emoji! Going to have to break this up in a million replies here ...
I was floored when I saw that price of $2k. I belive it was for the entire unit plus carburetor. Hopefully he will relocated that Ecm or at the min install an additional heatshield under it. I would install a fan with forced airflow if I had to pay $2 k!! Great job!! MChristmas
Before watching I was thinking heat related as well, but along another line. At the beginning the fan would come on when you enabled the lift, so I was thinking along the lines of a fault there. Maybe a "ECU reads engine temp, attempts to turn fan on, nothing happens or it doesn't get feedback of something happening, ECU shuts engine down"-scenario, but I guess it would have thrown a code for that. Too bad they potted the ECU, but, then again, that's not the worst practise given the application.
I am amazed customer paying crazy money for a new ecu box .... no chance of a specialist ecu repair ... diesel lump conversion money . My first thing would have been unplug the main controller and plug it into the ground plug to eliminate chassis scissor boom wiring harness I would have been in that controller box and checked key switch and e stop micro switches and the birds nest wiring within for poor connections With Skyjack excellent online diagnostic information and schematics and fault codes
Sadly the board is potted with epoxy resin when a few cold solder joints may be at fault. Perhaps what could have been an additional thirty minute repair and $2k parts saving. "Zenith...the quality goes in before the name goes on."
The owner should immediately move the computer to the Red bar mentioned and if it rains, treat it like a sugar lollipop. Otherwise better than the lifts I used when you had to direct the engine for every change. Maybe that would be better, to have all the controls in the basket, I would feel better 35ft up.
diagnose dan had a similar video on a benz with the same symptoms .he used a heat gun to duplicate the fault several times. he might have try to insulate the mounting surface to prevent future breakdowns
Fools rush in where Angels fear to tread!! 😳🤣. Miles of wire, relays, safety switches and goo potted ecm’s. Those usually have their own factory service tool as well AND a service manual !!! Well done. Believe me you did well hitting that thing. Ida done it with a sledge hammer!! That type of equipment, with so many government mandated safety systems, will make a good man drink... lots more than he normally would....
Hey Ivan I bet you had to change you pants when that thing went wide open . Would have made me piss myself 🤣😂 .. Glad you got it fixed great 👍 video buddy

Thank you
Ivan, you always give us a lift😃👍.Great diag!
Never seen you move so quickly Ivan when that thing went onto full throttle
Had that computer not been potted, you might have spent another hour finding and fixing the two-bit component causing the problem.
probably where the connectors solder to the board, even the potting doesn't penetrate well enough to keep them from vibration fracturing.
but GM OBD-1 TBI setups in that era were known for injector coil failures(low resistance) and cooking the ECM's inside also. hearing that one chatter the electronic throttle, I'd be leery of it going low resistance also. I never really dealt with the electronic throttles on them, but a coil is a coil :)
Great job sorting through multiple issues to get to the root cause.
As always, well done!! Appreciate the follow-up. Don’t think I would have slept tonight if you would have left us hanging. ;)
Soon as the diagnostic light started acting up I knew it was the ECM.
Great keep the videos coming up that’s great man I love it

You found it, it's fixed, happy times again! Not a cheap repair, but that's an older unit. Might be time to upgrade away from that machine.

I was floored when I saw that price of $2k. I belive it was for the entire unit plus carburetor. Hopefully he will relocated that Ecm or at the min install an additional heatshield under it. I would install a fan with forced airflow if I had to pay $2 k!! Great job!! MChristmas
Pretty soon you'll need a new starter too!
great work ivan you will be working for spacex at this rate :)
Counting..one..one..two..one..one..two reminds me of learning how to square dance in high school..LOL
Was thinking it's a catalyst booked but u pliered it nice amazing diag
Very nice video, thank you.
That was great Loved it.
That was cool. Good ol tapa tapa
You're the scizzor lift king.
Box? just put an ice pack on it 😜
Absolutely. With a balky computer or ignition module, pour ice water over it to cool it down and it should run until it gets hot again, as a test.
Good job dude I don’t usually get these until they’re late anyway
Before watching I was thinking heat related as well, but along another line. At the beginning the fan would come on when you enabled the lift, so I was thinking along the lines of a fault there. Maybe a "ECU reads engine temp, attempts to turn fan on, nothing happens or it doesn't get feedback of something happening, ECU shuts engine down"-scenario, but I guess it would have thrown a code for that.
Too bad they potted the ECU, but, then again, that's not the worst practise given the application.
Reminds me of the ol GM ECM tap test of the 80s and 90s...
I am amazed customer paying crazy money for a new ecu box .... no chance of a specialist ecu repair ... diesel lump conversion money .
My first thing would have been unplug the main controller and plug it into the ground plug to eliminate chassis scissor boom wiring harness
I would have been in that controller box and checked key switch and e stop micro switches and the birds nest wiring within for poor connections
With Skyjack excellent online diagnostic information and schematics and fault codes
Yes, it’s like your fuel pump tester, hammer, test starters the hammers are high dollar pizza equipment
$2000!!!!!!! No second guessing on this one Ivan.
Sadly the board is potted with epoxy resin when a few cold solder joints may be at fault. Perhaps what could have been an additional thirty minute repair and $2k parts saving.
"Zenith...the quality goes in before the name goes on."
Wow, that was trouble shooting!
You Can order that ECU directly from a Zenith industrial engine distributor, I just did one a few weeks ago, cost was around $950
The owner should immediately move the computer to the Red bar mentioned and if it rains, treat it like a sugar lollipop. Otherwise better than the lifts I used when you had to direct the engine for every change. Maybe that would be better, to have all the controls in the basket, I would feel better 35ft up.
diagnose dan had a similar video on a benz with the same symptoms .he used a heat gun to duplicate the fault several times. he might have try to insulate the mounting surface to prevent future breakdowns
well done again,you certainly earn your money.
Fools rush in where Angels fear to tread!! 😳🤣. Miles of wire, relays, safety switches and goo potted ecm’s. Those usually have their own factory service tool as well AND a service manual !!! Well done. Believe me you did well hitting that thing. Ida done it with a sledge hammer!! That type of equipment, with so many government mandated safety systems, will make a good man drink... lots more than he normally would....
Apparently the quality doesn't go in before the name goes on anymore!
Different Zenith, I think.
Excellent vlog ..
Hey Ivan I bet you had to change you pants when that thing went wide open . Would have made me piss myself 🤣😂 .. Glad you got it fixed great 👍 video buddy
Must have been 10,000rpm hahaha
Another cool case study
