Hi Fellow Mopars I wrote in this forum earlier in the year about a cracked ballast resistor causing the engine to die when put in D or R and attempting to drive. No problem starting or revving in P. The resistor has been replaced, but the problem is still there Since the resistors´ job is to protect the coil from overheating I was thinking that the coil might be damaged too ? I may have been driving with the cracked resistor for some time without knowing. Last year I did a lean-burn deletion and had this Summit kit installed: Summit Racing® Electronic Mopar Distributors SUM-851003 After the current problem came up I ordered an MSD blaster 2 - part no. 8202. It comes without a ballast resistor. The question is: Can I install the MSD blaster 1 -with the current resistor ? 2 -does it not need a resistor at all ? 3-does it need a specific MSD resistor ? Or is this not the problem ? I have tried looking at Q&A at Summit but nothing clear comes up. Any good advice is appreciated - I am not an elctrical wizard, but the car ran fine all last year before the resistor cracked.
