Hi Bill!

Thanks for the suggestions.

The starter solenoid is fine. There are two electrical connection male spade fittings on the starter solenoid. One has the factory wiring connected to it, and gives power to the solenoid when turning the key. I have installed a "jumper wire" on the second spade fitting. When I touch the other end of this wire to the positive battery terminal, the starter works perfectly every time. Your suggestion of installing another small relay to provide actuating the starter solenoid is a good one. This is in effect, a small amplifier.

I found the pink wire buried near the Power Stage. It is in a blue connector. Giving the pink wire voltage draws a small spark at the battery, but gives insufficient current to operate the starter, just like turning the key does not. That is a clue, but I haven't figure it out.

I may use a fine tip probe to gently pierce the insulation in the wiring to take voltage reading while my reluctant assistant (wife) turns the key to the start position.
