I have a 90 sc I purchased from an original owner and the car parking lights don’t turn off . Even with the car off they still stay on killing the battery . Anyone ever had any issues like this ?
I would start with the headlight switch move it gently in and out and see if you get flickering lights could be the contacts inside are bad and I'd imagine that it wouldn't be expensive or difficult to change just so you know the key on or off won't change if the lights turn on or off (maybe if you have the auto lights but otherwise no)
Figured out the problem. Previous owner had some undercarriage lights on the car and they wired it to 10amp fuse . I took the wire out and reinstall the fuse . Good to go . Not sure if it was grounding the switch
Thanks for the update. Always frustrating working on 30 year old stuff that has been through multiple owners &/or mechanics & having
no idea what they've touched.
