from shoebox's beautiful website
ICM Harness
A = ~10vdc-12vdc (or your system voltage)
B = 1vac-4vac while cranking
C = 0 ohms to ground
D = ~10vdc-12vdc (or your system voltage)
A B and C are correct. D is under 1v. is this a symptom of a bad coil?? im going to borrow one from work tomorrow and see is thats the problem. i tried a new icm today, not the problem thank god. 74$ for that
