The later rangies have a single 10v voltage regulator feeding both of those gauges. It's located in the instrument binnacle.

A little playing with a multimeter should let you trace from the gauge back to it's location, but you'll have to remove the instruments from the vehicle first.

A new regulator from dick smith is only a few bucks, but there's the hassle of wiring it in.
The gauge is basically an ammeter, 10v supplied to one side and the other side earthed though the variable resistance of your fuel or temp guage.

If you drop the panel by the drivers knees, it'll be only four nuts holding the binnacle down.

Unless of course they changed everything in the decade between our vehicles.

Both the fuel and temp gauges are supplied from a voltage regulator.
It's the metal can thing located in the instrument panel.

Mine displayed similar symptons a while ago, but it ended up being a fuse.
Have you got reversing lights?

First check would be the fuse box. Then check be the dimmer dial by your left knee. If that loses a wire then it's lights out.

At least yours should have reasonable wire lengths.

The headlights in mine take power though the fuse box by the passengers leg. That's about 6m more wire than it needs, giving 2v less than the front lights should get. :roll:
