I installed a new wiring harness. It starts from the key and dies as soon as the key is turned from start to run. This means the coil isn’t getting power in the run position. The new harness was made off the original as a sample. It has all new original type plugs, and the end of each wire is marked with the corresponding numbers in the schematic. I never checked continuity before, so I read up on it. My tester doesn’t beep, I have to look at the numbers. No options are marked continuity, but one has that funny looking upside down horseshoe looking thing. I put it on that. The leads won’t reach from ignition to coil, so I used alligator clip jumpers and a length of wire. When I first turned the tester to the ohms setting the display read 0.L, the instructions I found said that’s right. When I first made contact the display changed to zero, then started climbing slowly, stopping at 8.1. The instructions said it needed to be 1.0 or less to be at the opposite ends of the same wire.
Questions: Does this being the special type wire (to reduce power going to the coil) affect the ohms? Will the jumper wires affect the ohms? In other words, am I getting an accurate reading? The harness maker had the wire marked correctly and in the right spot on the ignition plug. If they marked the wires incorrectly, that’d mean it’s elsewhere on the ignition switch. Should I check continuity on the other wires to see if that’s the case?
Another thought, this wire goes through the firewall in a bulkhead plug. I believe I checked all of those wires against the schematic, but I could check again.
Pink circuit is momentary full power while cranking, green is power to coil in the run position.
