Oil light on, pls. advise. 200 1985

posted by  someone claiming to be Ted Y. on  Sun Jul 22 21:00 CST 2001 [RELATED]

Hi all,

After re-wiring my alternator (1985 245 turbo) due to a short in the wiring under the crank pulley harness, I now find my oil light on (motor running). Since I did nothing except replace and resolder 3 new wires (using heat shrink tubing) for the alternator and the two small black and green wires above it (I was told are for the oil press. switch), I assume the lubrication sys. is O.K. and I have a "short". My Bentley manual says that if the oil light turns on with the key in the "on" position (motor off) and the light remains on when I disconnect the wire, I have a short at the press. switch.

The problem is, I have re-checked my work and can find nothing wrong. I think both wires lead into the grey plug with 8 wires near the firewall, but between the firewall and the oil press. switch(?) they dissappear under the intake manifold. I have no idea whether or not they are "tied in" to any other wire. It is extremely difficult to see under there. I have a multimeter, but am just learning to use it. I hate to have the light on, and would like to correct the problem and make sure that the motor is recieving correct oil pressure. I would really hate to pay $250 for a new wiring harness and to pay big $$ to have it installed (don't want to do that big of a job myself) and I don't feel like removing the intake manifold and such just so I can clearly see what wires go where for a complete re-wiring.

I was wondering, the Bentley manual says (if I understand wiring diagrams correctly) that the black wire should be attatched to the "-" battery terminal somewhere, and the green wire runs into the back of the oil press. gauge. If the black wire is shorted, could I just create another black one spliced to the neg. battery terminal rather than try to figure out where the short is? Do you think it is the black one which is shorted? Or, could it be another problem?

If anyone has any advise, it would be greatly appreciated. My wife is pregnant and uses the car as her daily driver, but we are afraid to run the motor now in case the oil press. really IS low.

Thanks,

Ted (Bundy) Y.
