Lets start by saying Im not an electrician nor do I know much about wiring. After finishing a total gutting and rebuild of a house (wife insisted on one project at a time ), I have started in on the FJ (a 71' with 78' 2F). Just finished 4 wheel disc brake conversion (learned that POs can really mess up a good thing... long story, different time) and starting on the wiring next. After the rig sat for longer than Im proud of saying, the batt was totally dead (ie shot). After talking with the Interstate dealer and getting a new battery, I started with his advice. Using a volt meter for a bridge between the neg terminal and neg batt cable, I started taking measurements (all key off). Heres what I got.
Nothing disconnected = 12.43 volts
Alt disconnected = 12.45 volts
Fuse 1 (light) disconnected = 12.45 volts
Fuse 2 (horn) disconnected = 11.69 volts
Fuse 3 (spare) disconnected = 4.28 volts
Fuse 4 (meter) disconnected = 12.43 volts
Fuse 5 (wiper) disconnected = 12.44 volts
Fuse 6 (turn) disconnected = 12.45 volts
Both 2 and 3 disconnected = 0.223 volts
Im assuming that I have ground issues or a short in both circuits. is this right? How do I chase shorts in one circuit if both are having issues? What am I looking for? Why wont someone do this for me?
