Occasionally my bike is going flat. I checked the electrical system, the only issue I can find is if I test the current made by the alternator between 2 of the 3 fields I get a good reading, but the 3rd only gives me 5-6v (I.E. in fields a, b and c: a-b = good; a-c = good; b-c = bad) All tests on the alt come up fine, the windings all have less than 1ohm resistance and no shorts to ground and the field coil seems good and strong. Anyone know anything that might be wrong or should I just get a replacement alt and be done with it? Tim.
