About 2-3 years ago, I finished my truck and had the 6v generator rebuilt. It was fine but today I disconnected the battery and the truck died. I started it again and checked the voltage on both wires coming from the generator and there was no voltage. What should I do?

give the regulator a smack, points might be stuck

Find the "Field" turminal on the generator ground it with a jumper then meassure the "Armature" turminal back to ground on the generator should be about 8 volts engine running

Could my problem be a faulty voltage regulator?

I have the same problem today, when I took the postive cable off the battery the truck died. I tested the generator for voltage and it was dead. I removed the generator for a closer look. I looked into the back of the generator to inspect the brushes and found a wire going to one of the studs had broken loose. I went ahead and took the generator apart it was very easy. I found the generator had rust on the armature also. I'am going to go ahead and do a alternator conversion and do away with the generator. I figure for waht it will cost to have the generator rebuilt or even buying a rebuilt generator. I will come out spending just as much converting to a 12 volt alternator system.

Bill,

I checked the generator today like you said by grounding the field and checking the voltage on the armature. It still read 0v. Should I remove the generator and look inside it? What am I looking for? Should I adjust the brushes?

I would remove the generator and take it apart and check the internals for any wear or damage. Did you remove the wires from the generator before checking? If you grounded the field terminal then checked the armature termainla by taking one lead of your meter and grounding it to your generator housing and touching the other to the armature terminal like Bill said and your meter showed no reading then it is a sure bet your generator is bad.
