    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?

    Thanks

    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.

    VERY IMPORTANT to use a heat transfer compound. I burned up a regulator/rectifier module on my motorcycle once because I forgot to use it when mounting the unit.

    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.)
