Thread: BROKEN WIRE

Couldnt even see where the other end goes but it looks like it goes to the other side of the eng, and meets up with some sort of loom.
The two wires were yellow and black, and they go into a plug behind the oil filter somewhere. The black wire is the problem.
Does anyone know what these wires do, and whats not going to be working if one is broken.

Cheers,

G'day,
Just cheeked mine as I have access to them.

Very fine wires, my conduits bracking up too.

OIL PRESHURE switch mounted off oil cooler.

I assume the motor should shut down if no signal ?? Don't know for sure.

Cheers.

hmmm, thanks mate,

Thats how I found them also, the conduit had gone brittle and fell away from the wires.

Mite just head out and see if the car starts

well the car starts, and no strange lights on the dash, so thats a positive

Did the oil light show op on the dash before starting?(bulb check)

Being a black wire I guess its an earth?

Outher breads of cars use the diffrences in voltage (1 volt and up) to feed signals to ECU.

Cheers.

yeah mate, the oil light came up, and then went away after starting as normal.

Im sure its got to of come away from whatever it plugs into at the other end, as I pulled it out a good 2 or 3 inches before I stopped when putting on the new conduit and the yellow one has no movement at all.

Cheers

Don't worry , the black wire isn't needed, the oil pressure switch only has 1 terminal in it, the yellow wire is connected to it. The black wire is just poked back through the loom and sits there, not connected.

Thanks a heap for that JC.

Thats one thing I can cross off the list. The things you find when you start looking around can soon add up.

Cheers mate.

That wire can also be used for a turbo boost gauge or an oil pressure gauge for exact pressure monitoring.
