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?

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:
