I'm trying to sort out the electrical system of this car which has a 12v negative ground electrical system. The fuse box holds 3 glass tube fuses. With fuses removed and the 12v battery disconnected, 5 of the 6 fuse end clips have continuity to ground. The car has no computer and I'm thinking these fuse terminals should not be grounded. Am I correct and what's the best way to trace these faults? Also, the ignition switch has 5 wires leading to it and these also have continuity to ground, regardless of key position. Any help is appreciated.
