starts and moments later there is an electrical storm above the head

Not sure what you mean. If there is sparking under the hood you need to check the cap, rotor and spark plug wires. Do you have a magneto or a distributor?

Thank you. This is a Model A Ford and prior to this I haven't seen this. The charges don't seem to be directional - all over the place rather than what you might see in a direct short. Hence a "storm". The plug "wires" are uninsulated straps and the distributor and cap are new. I didn't see anything in regards to the coil or its wiring. ( That could have been because I was looking for the fire extinguisher.) Primitive for now but for 1931 it worked with a 6V Positive Ground system. For now it seams that my only option is to double check everything perhaps twice. I'll return if I find something. Thanks again, Steve

Thank you, Certainly would be a plus.

You can buy real insulated spark plug wires for your A if you want.
