what is the test for the charging circuit?
Does anyone have numbers related to RPM's that it should be putting out?
Do you just do a voltage check across the battery or a check across a load other than the battery?
Buy land. They ain't making any more of the stuff.

If you're testing the charging system out you check at the battery poles. Can't remember the exact numbers, but you should be producing 14+ volts with the engine up 3 to 4K rpm. Someone will have the spec shortly.


Yo can study here. Might have to scroll down and dig around. But it's all here:
