Where could these two circuits be in contact?
1965 Lincoln Continental worked fine when parked 24 years ago. Squirrels must have re-wired it since. High beam switch activates the starter and high beams. Starter switch activates the high beams and the starter. When dimmer is on low, no problems. Installed new dimmer switch - no help. Disconnecting the neutral safety switch does not change the problem. Where are these two wires likely to be in contact with each other? Must be 200 ft of wiring harness to dissect !
