electrical help - fan, horn, blinkers, temp

[Vombil]

[QUOTE=agr071;99651]Sorry about the delay, haven't been able to access computer for a few days. no probs mate your help is much appreicated

Washers - From memory have a + to the motor and earths out through the washer button. - I WILL BUY NEW PUMP & TRY

Horn - If the relay is clicking you are getting an ignition supply to the relay and the horn button is earthing the relay, so it should be getting a + to the horn and it earths out through the horn body & bolt. HORN DID WORK - THEN JUST STOPPED WHEN I WAS TRYING TO GET REVERSE LIGHTS AND OTHER THINGS WORKING.

Heater Fan = Switch has a + to the switch and 2 (or 3) wires come out of the switch. They go to the fan resistor. Then goes through the fan resistor and comes out the resistor and goes to the fan. (Full speed is usually switched via a relay) - FAN ITSELF WORKS - THERE IS NO POWER TO SWITCH. WHERE IS THE RESISTOR LOCATED ON WB? NOTHING I CAN SEE ANYWHERE.

Temp Gauge - MAY have gauge issue. If you put the wire to earth, what does the gauge do.

Oil Sender - Does it only have the idiot light? If so earth the wire with IGNITION on and see if light works. If gauge, do same as temp gauge and let me know what happens. - YES, IDIOT LIGHT

HANDBRAKE DUMMY LIGHT DOES NOT WORK AT ALL>




I noticed that with brake pedal depressed and engine running there was only 10-11 V going to brake lights at rear of a-pillar harness connecting point. All fuses are getting 12.5-14V with engine running (exceptions are the two on the bottom left of the fuse board).

Using your multimeter, put the probes into the washer pump wires. Press the washer button and it should show 12v. If it does you have a pump issue.

Using your multimeter, put the red probe into the horn wire and black on earth. Press horn and it should show 12v. If it does you have a horn or earth issue.

There is usually a fuse marked HEATER. Check the ACTUAL contacts infuse box (not just fuse) because if fuse is dirty, it'll show power on the fuse but NOT on the contact in the fuse box.

For the oil and Handbrake lights, they will have a power going to the globe and the wire has to be earthed to make them work. If you use your multimeter , the wire on sender and handbrake button will have 12v. If not check at the globes.

How did you end up with the blinkers and reverse lights?
(Would be heaps easier if I lived closer because this could be sorted in possibly an hour or 2)
