Default I'd really like to know.

Besides the obvious reasons, why are my modules crapping out...Please don't tell me it is inadequate ground...

No idea what you re using but I know with the pertronics I use it requires a somewhat specific coil. Mine is also an older one that will burn out if the key is left on.

Like Kill said...The electronic components used in Pertronix are sensitive to over-current damage. This happens if you use coils that are 'high performance voltage' coils that are sold everywhere. Pertronix does sell a coil, and I would only use that one. This assumes you are using a Pertronix system...you don't give much info here...

Interesting. I'm wondering what type of electrical system you're using, 6 or 12v, generator or alternator. I'm thinking about an electrical connection somewhere,anywhere that can be causing an over-voltage.

Oldreford,
I appreciate your frustration, but if you expect the Barn brain trust to find a solution, you must provide more specifics.

One cause is:

"Testing" for missing engine condition by removing plug wires while engine is running instead of shorting the plug to ground will damage coils and or pickup modules.

This practice does not leave any place for high voltage to find ground so it arcs and sparks around inside the dist where it blasts the pickup module or arcs inside the coil breaking down the insulation.

First few times it might just weaken the components until finally they die.

Any loose connections in charge circuit where the battery is removed allowing the generator voltage to spike.

An unloaded generator will spike as high as 40 volts.

Like loose connection on fuse housing on top of the starter or connections inside terminal box or Ammeter.

First few times it might just weaken the components until finally they die.
