I just bought a 1967 P6 2000TC and after a few days of driving it I encountered an issue,
I was driving it at night and could smell burning, and the side/park light toggle switch was scorching hot! Its internals must have melted and it no longer 'toggles' and is limp. The spade connectors to the switch were slightly burnt but are ok. I put a new toggle switch in (not a genuine rover part) with 3 terminals and connected the live to the centre terminal and the other two to the others. After doing this, only the side lights on the right of the car work, and the headlights do not work at all! The full beam still works. What has gone wrong? Can anyone help me? Thank you guys!
