Hello,
My oil level sender isnt working on my 1985 Turbo. With the ignition on the needle simply goes to the top on the instrument panel gauge.
I have two wires on the sender which is located in the O/S/R wheel arch. One wire coloured "brown with red dashes" goes to the centre terminal and is covered by a small round rubber cover. The second wire coloured what looks like "brown" can be found on a spade connector which is held on by one of the sender unit mounting nuts.
With the ignition switched on if I disconnect both wires and go across them in with a volt meter I obtain 12v. The "brown and red" wire is the positive and "brown" only the negative.
The problem I have and its maybe just me being thick is this;
Seeing as both wires are connected to the sender unit wouldnt there be effectively a short circuit. If I use my meter in voltage range and go from the centre terminal which I would assume is the feed wire (brown/red) and then to the sender casing I see 12v. Surely a positive and negative on effectively the same piece of metal is a short circuit.
According to the workshop manual on page 170-6 it mentions testing the unit. It refers to "removing electrical connectors", ie, more than 1 connector. The diagram as far as I can see only shows 1 unless this was a change somewhere on later cars.
I this correct or me being dumb here?
Thanks,
Chris
Ps. I have tried a new sender unit and connected the "brown/red" wire to the centre spade connector and put the "brown" wire to a grounding point and that made no difference to the fault!
