Do any of you have any knowledge of the physical layout of the wiring in earlier cars (mine is 499)? This past weekend, I fried the high amp wires on three of the power relays (horn, starter and fan). These wires are daisy-chained starting at the horn relay and are fed, I believe from the starter. I also have a dead short on all of the low amp wires going to the coil side of the relays (relays removed).

I still have voltage at the starter and the high amp side of the relays where the wires are burnt when the batt cut off is turned on. I do NOT have voltage at the input to the ignition switch…Looking at the “wiring diagram” it shows power going to the ignition from the batt cut off and spliced prior to the switch to the high amp feed on the relays. I am not sure this is accurate, or if it is, where the splice is located.

According to the diagram, the ignition switch feeds the low amp side of the relays and various fuses, but I do NOT have continuity from the low amp side back to the switch. Again, I suspect there is a splice somewhere, but short of tearing the entire harness apart, don’t know where it may be.
Bottom line is somewhere one or more splices are open and one is most likely shorted. If anyone has any idea where the specific splices are located, please share…

Thanks!
