Electical Gremlins in 85 carrera

[marktodo]

The 85 we found in a warehouse in St. Louis sat for most of the last 5 or 6 years. We replaced all of the gas & brake lines . This weekend I plan to do all the bushings in the shift linkage. It is driving really well , lots of power,straight and brakes well. It's also the only Porsche I own that doesn't drip a drop.
It has a small list of electrical gremlins. i'm wondering wether they are all independant or related.
Oil level & pressure gauges both pegged at max
Key symbol (red) on console usaully on
electric door locks don't work
Can't lock driver door by mechinical or electric means
electric window switch on drivers side for passenger window doesn't work
radio gets occasional heavy electircal interferance noise

Oil pressure sender is either broken or the wire is grounding somewhere between the sender and the gauge. Disconnect the wire and see if it drops. If so, then it's the sender. If not, then it's grounding someplace else and you'll need to trace the wire through the car (or run a new one).

Faulty OP sensor on my 85 was giving me fits with the parking brake light on all the time etc.

I would start with a remove/clean/replace of every fuse in the block, both front and rear. And an inspection of the grounds, including the trans to body strap near the starter.

Also, look for rodent wire damage, maybe something is chewed thru.
