Since I am neither have the space, nor the time right now for a part out, I thought I would try just one more time with my diagnosis.
(What was that wire that I fried from the "50" connection that seems to always be ground voltage? And why was it always ground voltage?)
I bought a remote start button, and want to know what to connect it to, and why the "15a" voltage is about 3v lower when not in the starting position.
I read up a little, and now see the volts correlate to the coil voltage and are probably 3v lower than the battery due to the in line resistor for the transistorized ignition. Ahh... Ok.
So what's the "50" connection, and why is it always ground? Oh... Is this just an extra/smaller bolt for the smaller wires that get extra voltage during the cranking? I remember from diagnosing the ignition on the white sedan 1971 250 that one ignition resistor is bypassed during cranking. So... Is "50" just the same thing as the power to the starter? And if my solenoid was firing/working, it would go to the 12-13v that the battery has??? Hmm...

Ok. So anyway, I should put the remote starter wires on "15a" and the battery hot. If my solenoid doesn't pop and provide current to the starter, then I know the starter solenoid is bad, and I might want to just replace it.
That's where I am. It's 21 F outside right now. So maybe tomorrow.
