Got it thanks. The file Bill mentioned is on the isolated ground wiring diagram is missing. It may be somewhere else. However, I've isolated the problem. All save one (generator side) of the mystery wires in the engine compartment have been dealt with and eliminated.The stop solenoid lead has diodes in it that were evidently cut away. Disconnecting that lead and the entire problem goes away and both generator and engine run happily and the interrupt in the Valeo solenoid (chatter of ground interrupt) stops. If anyone has the type and specs for the diodes in the stop solenoid lead, it would be much appreciated.
