This 1966 has a brand new factory wiring harness.

I installed a 3g alternator along with the PA system that plugs in where the old regulator was on the firewall.

I have a Duraspark distributor with a GM module and no spark.

I am getting 12 volts at the + and - side of the coil with key on. When cranking I am getting 9.6 volts at + side of coil.

Please help.

Long story it ran four years ago when I was trying to finish car for my son. Life got in the way adopting my nieces and here I am.

Heat-sinked the crap out of it in a empty Duraspark box. Ran extra ground using a jumper from #2 to a carburator stud.

Took cap off and engine cranked over rotor spun.

Is there a way to check these older gm modules?

Ok I'm going to get a new GM module and try that. The one I used had been laying around.

Thanks.

Measured the ohms between the orange and purple wire coming out of distributor with key off and distributor cap off. 615 ohms seem low after seeing post above.

Retract that statement looks like I'm in the middle of the range.

No motor in car when I got it but oem is certainly a thought.
