Post reverse lights always on
hi guys,

i have a 1981 928, and circuit 9 on the fuse panel blew the fuse. on this circuit i have mirrors, reverse lights, rear wiper, and blower motor.

my reverse lights are stuck on... disconnected the switch at transmission. fuse stopped blowing, but lights still on.

checked connector in spare tire well. no obvious issue.

i pulled the bulbs. however i would like to fix this issue!

blower, mirrors, rear wiper work. when i look at the schematic it appears that with the switch disconnected...the only way that i could be getting power to the bulbs is the connector in the well...

any thoughts?

david

Sounds like a short which are hard to find in the 928. Most lie inside the harness where the insulation breaks down and wires start to make contact with each other. I'm not an electrical person except to follow the wire back to the switch, or run a new primary wire.

hi, and thanks. i know that the electrical on these cars can be problematic. as of right now everything works except this circuit. i do have further testing to do, but was hoping someone had already been down this road! :)

what i do know for sure, is that if i dont stay on top of it... one to the next!

thanks,
david
