I unbolted the controller from the chassis ground its hink sink is in contact with and tried to jam a peice of plywood between the controller heat sink plate and the chassis. Becasue of the bad angle and the time of day I'm not completely sure i got the contact 100% eliminated but it did reduce the voltage between pack neg and chassis neg down to about 3 volts with about 140 volts in the caps....does this help anyone out???
