lg1969 Just make sure you added silicone thermal grease under the module. It makes it easy to transfer the heat the module produces. The modules in a HEI are known to short because of heat.

redneckhotrods I had the module tested at Autozone,and that was the problem. It works now

redneckhotrods If the coil is connected to the distributor there is no power to the coil wire.Now I hooked the coil up to the battery not the distributor and there is power to the coil wire. Would that indicate a bad ground in the dist?

redneckhotrods The wires are in right,I'll check the ground

vsmidge68 Check Ground Strap In Cap For The Coil.. Poor Ground Coil Run Hot Fast...

T-bucket23 Do you have the power wire connected to the TACH terminal by any chance.

Jmark Hmm, the Mallory is a stock replacement HEI. There is a wiring harness that comes out of the base of the dist. and plugs into the cap. That plug has, I believe, Red, Black and Brown. NO other wires should be attached to those 3 wires. There should be another wire coming from the ignition switch that plugs into the "+" spade on the cap. The "-" spade is for a tach hookup.

redneckhotrods I have blk to blk red to red and yellow to yellow, Power source is hooked to the red.
10-11-2008 03:40 PM
Jmark Then I'd say you have power to one side of the coil and the other side is grounded, ain't gonna work that way! LOL

Are you plugging in the correct wires onto the correct terminals? Sounds like you've got something backwards.

redneckhotrods Ok,put another coil in it and it instantly heated up to the point you could not touch it.

Pull the coil and check ohms on the circuits as per Mallory specs. IT might be shorted, etc.
