Well i checked the voltage on my generator today ...on the load side of the cutout I had battery voltage ...on the generator side with the engine reved up I got 1.2 volts .....I motored the gen and it turned in the direction of the motor ...I had .2 of an ohm between the case of the gen and the Positive post ... I installed a ground wire to the motor to make sure it was grounded..... The field coil drew about 5 amps and put the armature on the growler ..all seemed good ...put the gen on a test bench and it ran 7.2 volts ...now nothing any Ideas before I tear it apart

Thanks
 
With the engine running at about 1000 RPM, momentarily jumper across the cut out and see if the generator then is charging.

If so, change the cut out.

If it had 7.2 on the bench test, then it should have the same on the car. I was going to suggest a poor ground at the mounting bolt, but you said you used a jumper wire to ground. Just be sure the clips on the jumper wire are soldered to the wire at each end. I had an alligator clip once with a bad connection because the metal was folded over the wire insulation, and the wire didn't touch the clip.
 
Tom I put a #2 cable from where the positive is bolted to the frame and the other end bolted to the bellhousing and have .2 of a ohm from the positive terminal to the case on the generator case...I'am thinking a wire fell down on the armature
