Have a 1986 Overnighter. The key pulls out when engine running and last summer couldn’t turn engine off with key. Pulled main panel off and lots of wires. My owners manual does not give a schematic and I’m afraid to tackle this project. Granted the turn engine off problem only happened once. Bought a new key will still pull out when ignition is on. Where can I find a wiring schematic for wiring coming out of the ignition switch. Any help would be appreciated.
