I have an 1974 Pontiac Grand Prix that was imported to Sweden in 1976. It has been sparely used and I have only been driving it for summer. A few days ago I replaced the electrical contact for the trailer. Everything seem to work afterwards and I continued to install a windshield washer kit. Suddenly everything shopped working, note the fornt headlights glow. Not even the backlights or parking lights has power. The car is completely dead and noting happens when I turn the key.
Is there anybody here that know the difference between the headlights and the rest of the electrical system? Surely it must be 2 different powers supply when only the headlamps wrk. Can it be a fusible link that has blown? '
I tried to measure and there is power in at least 2 or 3 pins in the bulkhead connector from the motor compartment to the driving compartment.
