ignition modules...
My chevy truck keeps blowing ignition modules. It has happened twice. both times it was after an hour of running the engine. I have a new coil, with an internal resistor, new alternator, new battery and new regulator, new spark plugs.
Any ideas as to what is happening?
ThanksGodxilla-Stroker

1 (Ground the distributor.
2 (Disconnect the tach and see if the problem goes away.
3 (Make sure you put the silicone grease under the module.

A common cause of module failure is high voltage. Even a new regulator can put out too much. Do you have a voltmeter?

dielectric compound on bottom of module,
no cheap brand modules such as Autozone etc. ( they got a lifetime warranty & you'll need it.)
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
