Gauges Problem

Post by **Alspos** » Mon Jul 07, 2008 4:00 pm

Tacho works. Boost works. Oil/temp/amps and fuel gauges don't work.

I've swapped over instrument clusters with another and same problem continues. I've checked the under dash fuses just in case, all seems fine.

So I'm guessing a wiring or a fuse issue somewhere along the way. Anybody point me somewhere else? Is there a fuse block or something I'm missing. A connector somewhere else?

HELP! :?

Thanks

Also.....what colour is (LR) on the wiring diagram?

Blue with red trace

Diagram shows 3 LR's, I only found one and two whites with 12V on them. Grrrr........

This farken thing is giving me the irrits.

Ok....things I have done -
Cleaned earth lead from engine to body to battery.
Tested continuity of wires from engine bay to instrument cluster for temp and oil senders. Test ok.
Checked continuity of earth pins in gauge connectors to the body, all read about 0.4 ohms.
Check fusible links, all have 12V when required.
Disconnect wire from temp sender, and ground it, gauge needle rises slowly. Same with oil pressure sender.

Car is running now as I think I have fixed a fuel pump issue, but the gauges (fuel/oil/temp) still refuse to work.

Any other tips, clues, magic incantations that anyone knows that may help me out?

sounds like a voltage reg in the instrument cluster, although you swapped a different cluster in yes?

Yes, I have a spare cluster and it has the same issues.

Do all these signals come from the ECU?

No...from the senders on the engine/fuel tank.

my temp gauge does the same thing...
however last time i was in toowoomba it was working fine, then i come back down the goldie and gauge not working.... wondering if being higher up (in the mountain range) has something to do with it??

If the gauge goes to max value when you ground it to the engine at the actual sensor then the gauge is working.. Leaving the sensor to be the likely culprit.

have you tried measuring the resistance of the sensors to ground of the temp & pressure sensor with either a running warm engine vs a cold non running engine?
