Check battery voltage getting to either the Field post or armature post of the generator.

In general, there are TWO types of generators:
Field ground. Armature ground generators.

I don not know which type your generator is because i don;t have the books or an original to look at. If some one has modified the generator from original ground type to the other type (usualy done for regulator swaps) then that could be the problem.

The SERVICE manual should give somekind of generator test procedure BYPASSING the regulator. That test should be done BEFORE taking action on the generator. Should be done now that u have a continued problem.

SO in summary:
Possible incompatible regulator with generator grounding type.

Possible grounding (armature or filed coil) of generator has been changed or is incorrect.


First need to run the test bypassing the regulator. Note that if the service manual test indicates to ground the "F" terminal and that does not work then try the "A" terminal.


First follow the test procedure of the manual !!!!!!!
