Spark gap too big ??

[stvincnt]

I recently did the Teamrush upgrade on my 79 CJ5 AMC 258 i6 / 4.2l c.i. I've noticed my ignition module is getting very hot while running, my alternator is also. I have cleaned all of my grounds to the block and even grounded the Ignition module body to the negative battery post and still can't seem to get the thing to cool down. And yes I do have a new ballast resistor installed. I did regap my plugs to .50 as it was suggested in a previous post. But i also read that too large of a gap can fry the ignition module. Any thoughts would be great

Do you have the MSD 6a ignition module?
MSD says you should gap the plugs at .050" to .060". Check out this link: http://www.msdignition.com/uploadedFiles/MSDIgnitioncom/Products/Ignitions/6420_instructions.pdf

Look at the top of page 3

If that's MSD's recommendation then the gap must not have been the cause of the failure.
