Well I have aux power, plugged my grinder in and engine increased speed and grinder worked fine, i got so frustrated that i shorted across the main cable lugs thinking maybe there was something wrong with the leads and still got the same result. no increase in rpm and only min. spark (about like a six volt battery no matter what the amps were set to

Thanks

What this tells You is that the exciter is working, no more or less. The exciter makes the field current for the big generator, and is regulated by the fine controll rheostat. Be sure that the exciter current is getting to the field, poor contact at the rheostat, or burned out rheostat winding could be a problem.
