Hey guys as some of you might know I have been having a problem for a while here with my randomly shutting off. Well I through another optispark at it and well the problem got worse, it will not start at all now it only backfires out of the exhaust. Well l when testing the opti I got a rather interesting reading. The read are supposed to be
Optispark Harness
A = ~5vdc
B = ~5vdc
C = ~12vdc (or your system voltage)
D = ~0 - 0.2 ohms ground
Well for position D I got .865 ohms, what does this mean? And what should I be looking f
