Temperature light problem was also due to the bulb holder on the PC board. The bulb was not contacting the brass tabs in the holder. I tried a different bulb and all is OK.

Checked GEN light operation by grounding the brown wire from the regulator plug. Light comes on when this wire is grounded.

I'm pleased these problems were found and corrected before getting the car running--much easier to get at the wires now.

Next step, I need to provide +12 volts switched by the ignition switch to the MSD system. I see there is a tab near the center of the fuse panel that does switch on and off with the ignition. I don't think there is a +12 source switched by ignition in the engine compartment, so will have to run a wire through the firewall. I believe #16 wire should be adequate for this.

Also need +12 for the hood tach light, also switched by the ignition switch--probably can use the same source since I need to run a wire for the tach signal from the MSD box, also.
