My 860 6 volt system is not charging, From the testing I've done, I suspect the generator is at fault. With the following information do you agree? Or are there any other methods of testing before I remove the generator.? Charging system is factory 6V configuration.
First I flashed the generator (Bat to Field). The voltage at battery when engine is running is still only 6.2 volts. Ammeter indicates no current (zero) when charging, but negative charge when I turn lights on.
With jumper wire between Armature and Field of the generator, engine running, still no charge at ammeter or battery voltage. Does this prove my problem is gen. and not the voltage regulator. I"m not sure on how to test the voltage reg.
Last time the generator was rebuilt was about 10 years ago.
Is it time to pull the generator off and rebuild or inspect? Thanks in advance! The archives have been a great help.
