Gauge Trouble

[haydo]

Coupe of the gauges are playing up in the girlfriends car.

The gauges in question are the fuel gauge and the temp gauge and they both sit next to each other also.

Apparently it just happened over night.

The temp gauge has just completely stopped and fuel gauge reads 3/4 when the tank is full.

I find it odd that they both started playing up together.

Going to have a look in the weekend any ideas on what to look at?

The should share a voltage regulator and they do give trouble.
