Is it the original coil or an aftermarket replacement?

Those rotors did have a history of shorting out to ground.

You may want to try an OEM coil. I don't know anything about the chrysler coils.

I suspect that the voltage from the coil is too high and is breaking down the rotor.

Thanks for the response guys
does anyone know the base putout of the original coil so I can see if the new coil is putting out to much
that would really be the only way to see if its to much
thanks in advance
