What to do if you wire a GM alternator and the engine won't shut off

- I purchased a 1955 Chevy truck and the alternator was not wired. After wiring the alternator and starting the engine, the engine would not shut off. I found a fix on Chis Craft's channel and applied his fix to my truck. It works and it's simple.
Yup. Ran into that before wiring a GM alt to an old military jeep. Never to old to learn. Glad you got it worked out.
Thanks Paul. Your time is appreciated.
There you go Wyatt, nice work in just wiring a bulb in the excitation circuit for the alternator. Keep up the good work!
It was lesson learned from another channel Chris Craft. Easy fix that had me going there for a while.
Nice work! Reminds me of some of the "stuff" we had to do in the field to keep the missions going. Maintenance rules.
I like that..."Maintenance Rules"!
Proof of concept. Ivan would be proud of you Wyatt! Nice job.
I stole that from him. :)
Somebody has a label maker just like mine. Going to keep that little gem tucked away in the back of my mind where I can find it. Thanks, good one. doug
The labels were there before I got into it. I have a label maker too and it does come in handy. Thanks again for watching.
Oh God I hate wiring. One little mistake can mess everything up and take hours to days to find. Good luck buddy. -John
Tell me about it. I spent three days working on wiring on this old truck and I'm worn out! I consider myself fairly intelligent but electronics intimate me.
Yep thats what I thought you would have to do. Nice fix!
Old school fix that I never hard of before. I'm learning all the time.
That's handy to know! Especially since I run older stuff, LOL, i can see this happening to me one day!
Your up late and second to watch the video. We didn't even cheat. lol
I'll keep that in the memory banks. Handy tip!
Thanks Johnathon.
Well that's different. I usually stuff potatoes in the tail pipe . That works too.
More dramatic too!
Sometimes on theses older models we have to adapt and overcome ! :)
At least it's easy to work on. Everything is accessible.
Sometimes we've gotta retrain the angry pixies.
A good point Zig.
The dash doesn't have a charging warning lamp? Perfect time to add a little red light! =)
No it doesn't but it does have a volt meter. Now I just have to research how to hook it up!
Really cool never knew that God Bless buddy
Old tricks I just learned. :)
Huh.... This is one of those things that could drive you crazy... Good to know!!! ;-)
It drove me crazy. I was happy to see it was an easy fix. Thanks for being here Bill.
I've never had that problem. A bad diode is causing it?
You know, I'm not sure. I always thought the diode was to protect that alternator, not the wiring back to the ignition switch. DriveShaftDrew suggested it had a bad diode as well. The video I watched to find a fix didn't mention it, he made it sound like it was a normal thing that you had to include in your wiring.
Nice work! I wonder what kind of wiring harness is in that Truck?
Multiple wiring harnesses until yesterday. The main one is from "EZ wiring". I removed a lot of unnecessary wires and have a video later about that mess.
It's electrical magic
This stuff scares me. (ha ha)
yup or replace the alternator as the diode is bad causing feedback lol
could use that as a test right at the alternator as well rather than trying to work under the dash but good video and proof it works
Yeah your right. I was working under the dash anyway on another project so it worked out well. Thanks for the comment Drew.
That's pretty wacky!! Good to know though!!☺
I was scratching my head on this one. Thank goodness for CZcams and smarter people than me.
Well ain't that something, was it a one wire alternator?
Shoot, I should have included that but you can wire this as a one wire or two wire. I chose to wire it with one wire and the other (exciter) wire goes right back to the other terminal on the alternator. Your first!
I think I would start making my crazy panic noises and wonder what I did wrong.
It was a bit strange but I just un did what I did. (ha ha) Meaning, I wired the alternator, so when it kept running I just unplugged the last wire I connected. Then it was off to CZcams to find the answer! And to talk to friends like you. :)
