rittenrotton 4 Report post Posted August 4, 2022 I need some help, I'm having an issue with my coil wire boot melting. This is the second wire this has happened to. I have an msd ignition coil and hei spark plug wires. Any suggestions as to what is causing this? Could it be a bad ground on the coil? Quote Share this post Link to post Share on other sites
Mach1 Driver 560 Report post Posted August 4, 2022 I would guess that either the wire connector isn't engaging with the coil, causing a spark gap and the resulting heat, or a crack in the coil tower insulation. Could you strip back the boot and run it in the dark to see what happens? Quote Share this post Link to post Share on other sites
