Bimbling home in my 72 Beetle yesterday, engine lost power then died. Lost all warning lights, horn, headlamps and the starter itself. Car now home and I have determined that the power to the ignition switch is OK, by taking the plug off the back of the keyswitch. There are three terminals in adition to the supply. Shorting out in turn to the live one does the following: Starter engages and turns engine; next one powers headlamps, and the last livens up the radio. However none activates the wipers or brings up the oil and charging warning lamps. The workshop manual wiring diagram is insufficient to help me any more. I believe it should be possible to rig temporary switches to substitute for the action of the ignition switch, using the key for the steering lock only. Does anyone have a circuit diagram or any info to help me understand this fault. The next question of course, is how do I eventually remove and replace the ignition switch ? Many thanks in advance !
