Gauge Problem

[eXc]

Hey Guys

I just installed a new aftermarket water temp gauge.

When I apply the brakes, the temp moves up 2-3 degrees, headlights move it up 5 degrees...

Is this a faulty gauge? Or do I just need to wire it better?

I mean I can't see how it can do that, the power for the back light should be totally independent from the temperature sender?

Cheers

It only happens once the gauge is above 80 degrees...

At a guess I'd say the earth/negative wiring is a bit dodgy. Where did you run the power off? Cigarette lighter?

Yeah +ve from the cig lighter and -ve I did to the chassis near the gear stick base.

I guess I'll try a different +ve when I get the chance

I use the +ve from the cigi lighter for my gauge, no problem.

For the -ve i used the wire at the cig lighter as well, im not a fan of grounding everything to different bits of metal, its easier just to solder it to a wire.

Maybe use a multimeter to check what voltage the guage is getting.
