Well an issue has arisen on my 55 Pontiac. Wisdom and advice is sought. It wont start. It cranks over freely, new battery. I've just started examining things. I have a good ground at the points, gap is right, i have 12V at the coil during the keys normal running position. When I turn the key to start, the engine cranks but the '+' side of the coil drops to zero volts. I don't believe that should be the case as it would indicate that no power is being applied to the plugs when starting. I have not checked to see if I have spark yet at the plugs while cranking. I have not checked to see if power is coming from the IGN on the ignition switch. I have not replaced the coil resistor on the firewall, it shows 12v at both sides. Coil, points, condenser, rotor, cap, wires, plugs are all new and oem or better. I have not replaced the voltage regulator ... yet, its in the mail. Odd thing, initially when i got the car, two wires on the starter were twisted together and electrical taped...i put them back to original...I don't wonder if that was a 'hot wire' to make this work or perhaps im missing something. Any thoughts?
