hey guys, I just installed a new msd hvc 2 coil on my car because of another coil arcing. The car runs fine. just for fun , though , we shut all the lights off in the garage to check the rest of the ignition wires.We did see flashing , not arcing , at the spark plug boots. i did put dielectric grease on the terminals. I have seen this before but just wondering what it is and if it is normal?It's got an msd 7al2 and both heads are grounded.Thanks.
I agree You need new wires!!!!!!!!! You should see Nothing if you shout the lights off...You are producing a ton of resistance that will cause the ignition
to fail sooner or later!!!!!!!!Good luck
Make sure you don't have too much resistance somewhere else. Cap and rotor, and rotor phasing need to be good. Also tighten up the plug gap, .030 should be good. When going to the Digital 7 and HVC II in my new car I fried the center conductor on my HEI distributor, I had to get a low resistance one that MSD sells.
