G14 James Posted September 18, 2014 Share Posted September 18, 2014 so i have put in a new alternator, new battery, new battery cables and purchased a new voltage regulator, after it was installed it seem fine until the vehicle is started at which point it begins to smoke. I put the old one back on and it works fine. is there a way to test them to see if the old one has already burt out what the new one seems to be working on burnin out. Or could they have given me the wrong one. The connectors are all the same just the internal look a little different but i thought maybe that would be just upadted.

Demon Brat Posted September 19, 2014 Share Posted September 19, 2014 I just did the same thing. Replaced the alternator, distributor and voltage regulator. Started it up and it ran like a champ....then smoke started coming out of the back side of the VR. I shut the truck off, cussed a little and checked everything again. Everything seemed fine. Started it up again and thought to myself, screw it, if it is smoking it is probably toast anyway. After a short time it quit smoking, none of the wires from the battery, alternator, VR or distributor were hot and everything seemed to be operating correctly. The back off the VR where it screws to the fender is a little warm but that is all. Inside the VR is an insulated resistor of some type that may just smoke the first time it is energized...I don't know. All I can say is it has been a week and everything is running perfect...knock on wood. I will let you know if it starts on fire or blows up, but as of now, all is good and no more smoke.
