No Spark

[mduffy216]

Hi
I have a mcm330 1982 with TRS drive, GM 454 Engine, Mallory distributor with points and condensor. I'm getting no spark from coil wire to dist. I checked wires to coil positive 12.5v when not connected about 4.5-5V when connected to coil.
Any advice on trouble shooting coil would be helpful.

FYI New plugs set to .035", new points set to .016", new condensor, cap, rotor,

Thanks

Re: No Spark

Replace the coil, they're only 30-50 dollars. It's the easiest way of trouble shooting
