I ran a 16ga wire between the generator housing and the regulator frame and a digital ohm meter connected across those two points should read zero ohms with clean connections. Generator and regulator now respond very well - no fluttering of the ammeter.

Next, I found that ground for the starting circuit went from the battery plus to the firewall and about 18 inches further away, the ground strap for the motor was connected to the firewall and then to the motor - result 0.35 volt drop. I ran a 1 gauge copper cable with copper eye soldered with silver bearing solder from the battery plus to the firewall where the engine ground strap was connected with connections sanded clean and tight. Voltage drop now 0.1 volts. Steel does not have the conductivity that copper does - many rungs down the ladder. The starter is much more responsive.
