1982 gas ezgo overcharging

[bschleuning]

Ive searched and couldnt find the answer i was hopin for , anyway i have a 82 ezgo that i replaced the brushes in the started/generator and and blew out the housing with compressed air, it is overcharging to the tune of 19+ volts, i tried adjusting the regulator with no luck, replaced with a known good one and still no go..all terminals seem to be clean and tight, if i remove the small df wire from the generator and it still overcharges is it possible i need to take off the generator again and look for something inside of it for another problem, what about the small red d+ wire on the regulator? can i use a jumper to do any tests on these small wires before i take generator apart again? thanks
