1996 Mercruiser 3.0LX Ignition Module

[jminator2002]

What would cause my ignition module to overheat and short out?? I just replaced one and put the old one back on cuz the new one would not let me put the engine in base timing mode. The engine would just kill. I put the old one in and the engine would stay running but no base timing mode so I'm getting another one and see what happens.

The reason I replaced the ignition module was because the old one would overheat in the water and shut the engine down leaving me stranded until it cooled down then I could move again. The new one did the same thing. Could it be something in the ignition shorting out causing the module to fry out?? I did have a fuse blowing at the starting key, bypassed it cuz I had no fuses. Did I open a can of worms??

Did you put the heat sink compound on the module before you installed it?

I have also installed brand new modules that were bad right out of the box. One time (about 5 or 6 years ago) I had 3 bad ones in a row. Ordered 3 different times.

Very good chance that killed the module. Or could be the dead module killed the fuse

Yeah I did put the heat sink compound on. I called the boys at West Marine where I bought it and they're gonna get me another one. You're probably right tho that the mod killed the fuse. Let see what happens when I install the new one again. I don't think my distributer would be bad cuz otherwise I don't think it would even run.
