Thank you for responding Bob. This is the original 6V neg ground system. Though I did rewire the complete harness a few years ago. Per your suggestion, I moved the + battery cable end to ground through the oil filter bracket bolt into the head. Made sure it is a clean contact. The battery reads 6.5 volts and the distributor reads 6.4 volts with points open. Again, no spark when pushing the interlock switch and nice blue spark for the few engine revolutions after I release the switch. I am still suspecting the interlock, or possibly the voltage regulator which that switch is wired to?
Thank you, John.
