IT LIVES
A coil change, a few rerouted wires, and an extra engine ground strap and I think I have the issue solved.
I was still feeling pulses of electricity after the extra ground strap from a head to the main ground distribution block, but it wasn’t as intense as it was prior to that.
Now I’ll admit, I’m not the healthiest guy, in fact I’m susceptible to a rather embarrassing case of plumbers crack 😬
As I was handling a replacement coil wire, my inadvertently exposed region bumped the carport wall and I felt a slight shock. Not enough to hurt, but more like static electricity?
Either way, I moved the coil wire to be more perpendicular to the main harness rather than parallel, threw on some convoluted tubing and the arcing seems to have stopped.
I pray this thing stops consuming coils from here on out.
