Temp gauge

Post by Alanb67 »

Looking for a bit of advice again......sorry. I posted a while back regards my temp gauge. I wasn't wired up. I've found the wire to connect it up but the temp gauge just shoots up to the top. Same as the fuel gauge. I cleaned up the connectios on the fuel gauge, now i get a reading with the ignition on but with the engine off. As soon as i start the engine the fuel gauge shoots up same as the temp gauge. Anyone any ideas......sorry again.

Hi,
Maybe a faulty voltage regulator? That's the first thing I would check.
It's easy to test. Take the wire off the temperature sender and test the voltage with a multimeter. It should read around 5V.

Here's a how-to guide on replacing the regulator:

A 7805 chip costs £1 or less, so if that's the problem, it's a nice cheap fix.

Thanks. I'll give that a go. Sounds like it should do the trick. Thanks again.

Hi,
Sounds like a job for a circuit tester or multimeter to find out where the power is being lost.
The place to start would be the black/wire fed from fuse number 7 and work towards the gauges from there. If the rest of the warning lights etc on the dash pod work, I would suspect a wiring fault somewhere between the multiplug and the gauges themselves.

I had power before i did the regulator now nothing att all. I was thinking maybe a bad earth. I'll check the wiring.

Took the module back out then put it back in and the needles are moving again. Only thing is they are just doing the same thing as before i put the new regulator in. He connection between the module to the back of the clocks is a bit dodgy, dont know if that would cause a problem. I think it must be a bad earth somewhere :banghead:
