flashing around spark plug boot
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.
