just got the car and was doing the basic tune up when I went to change the distribator cap and rotor two of the cap screws broke off and one was already broke so I had to pull the dist. to drill the holes out after putting it back in and all was going good untill the ICM burned out so I replaced it and after a day of driving it has burned out again what could be causing the ICM to do this should the single wire on the distribator cap be pluged into the bat. or the tach. could that cause it to short out or something else please help thanks... Steven,,,, Check the bat connection it is right so I replaced the ICM and it burned it out again that is three so far is there something I have done to cause this and if so what could that be thanks..

Wire goes to BATT and yes if on TACH your putting coil power supply through ICM then to coil. 12v as to 5v the ICM normaly gets.
