Here's what I did tonight. Removed and cleaned connectors at the coil; applied a little dielectric grease before reconnecting. Then went to the FPR relay to check 31b. I couldn't get a signal by sticking the probe on the test light into the back of the connector, so I disconnected the relay and inserted the probe in the plug side. I didn't tell whether I got a flash or dim glow, but I did get an H*** of jolt when I cranked it. I was holding on to the metal housing of the test light at the time to keep in place and dropped it. My arm still tingles; must have given my nervous system a test while I was at it. I guess that must mean that 31b got power from the coil. I also tested the ground position of the FPR connector at 31 and got power to the test light when I connected the other end to left side of fuse 7. The only circuit that I haven't been able to get power from is the one connected to position 15 on the FPR connector with ignition switch on. Does this mean that I've traced it to the circuit to the ignition switch or the switch itself? And, if so, what next? From the wiring diagram it looks like 15 on the FPR connects to fuse 13 and goes to the ignition switch if I am reading it correctly.
