Hi Darryl,

The volts at the resistor (and everywhere else!) should go up after the engine starts , not go down .. the gene should kick in and charge the battery at a nominal 7.4 volts or similar, depending on the regulator setting. Your volt readings make no sense ! Does the ammeter on the panel show a charge ?

Yes, a good idea to get another voltmeter and check it.

I know those 4.5 volt coils do behave strange.. I often had a almost dead flat battery and the motor would barely turn over... it would growl and just manage to get over a compression point... despite all of that, the motor would fire and start
