kts68: Should have said it before, but if you intend to use this car on tours and the like, it really makes sense to remove the generator and check it out thoroughly, even though that may not be the current source of your problem.

It has a rear bearing, but the front bearing is on the timing chain so it's difficult, even here, to find a shop that can bench test the unit as it takes a special jig to support the armature. But even without a dynamic running bench test, a good check over, new brushes, turn the armature if necessary, check for shorted fields and segments, etc. will all ultimately lead to a more reliable road car.

BTW, that voltage at the battery in static condition seems a bit low, the normal voltage for a single lead/acid wet cell is about 2.2 volts, so it should be closer to 6.6 volts.

EDIT: Original equipment for 740 and 745 was Owen-Dyneto CD-865 generator and regulator 20220. Regulator relay should close at 6.5 to 7 volts, and open at a 0 - 2 amp discharge. Contact gap 0.015", core gap with contacts closed 0.010". A 6.5 volt cut-in corresponds to about 550 engine rpm, 7.0 volts to 600 rpm
