Hello all,
I’ve been trying to solve the problem of my druck press gauge not working (pretty sure it’s the sender) and after pulling the gauge I found this burnt connector? It has a blue and white/blue cable going into it. Also In the second pic I’ve attached is a switch that is under the dash. Does anyone know what this is for? I am guessing its aftermarket.

Thanks, Jeremy

What does it physically connect to?

Well the two wires in the connector go to separate bundles that disappear behind the dash. One of the bundles has a wire that goes to the oil warning light and the other bundle has a wire going to the battery warning light. Could it be a common shared between the lights? If so what could cause the connector to burn like that? I’ve checked both lights and they still work. Bentley manual should be here next week it should have a wiring schematic of this right?

Thanks, Jeremy

what year is the car? It looks like it may be the switch for the left & right mirror selection. that's where it is located on my 88 Carrera.

^ yup

oh and it may help for you to put your car model in a sig or post you require help on . The wiring was significantly diferent from SC to Carrera

Thanks Ron and Iceman! Id given up on the passenger mirror. Ha I was thinking it was weird that they would only motorize one. I’ve been looking for the owner’s manual for my year but have yet to find one. Does anyone know if there is a way to obtain a digital copy of an owner’s manual? Anyway thanks for the advice on the signature Iceman, your right it would help if you all knew the year. It’s a 1984 Carrera witha few modifications done by PO. It’s been a very interesting month and a half since I’ve owned this car trying to figure out all the back info on it but I’ve had a blast doing it. Anyway I’ve held this burnt connector in my hand with the car on and trying to turn on and off various items and it doesn’t get warm and everything seems to work well (no blown fuses).

i will check my Bently schematic for a blue and white/ blue cable.. but my sc may be different. someone with a Carrera Bently should be able to tell you

Thanks Iceman but I had my colors off they are both blue wires only. Placed my order for a Bentley this weekend should have it by the end of the week.

it is very easy to fry the complete wiring harness if you cause any sort of flaming short in the dash . - happened on a headlight wire on a 911sc i owned 15 years ago.

theiceman

wow .. flaming shorts sounds very painfull ..

Unplug the blue wire and see if the mirrors still work, or if the cross-over switch for the right mirror still works.

NOTE: Be extremely careful that no hot wires are touching ground when you turn on the ignition switch.

theiceman

found it .. i thought it sounded familiar .... its the indicator light wire that comes directly from the alternator .. my guess is you have had an alternator over voltage condition from the alternator/regulator at some point.

Peter Zimmermann

ice, just curious...is that for an external regulator car, or an '80> internal regulator car?

groovzilla

good one

theiceman

Pete thats from a Carrera manual i had lying around so i imagine internal ..
