The fuel gauge on the Vixen has just started playing up. With ignition on it indicates just over empty however much fuel is in the tank. The gauge is working as the park (ignition off) reading is well below empty, so it does move up when the ignition is turned on.

I put a volt meter on the fuel gauge and it gave a continually fluctuating reading of between 3v & 9v. Is this right???

I have also found what I think is a voltage stabiliser behind the dash. 4 terminals with 3 green wires :



Can someone confirm this is what I'm looking at. All gauges are Smiths (not original AC) and others all seem to read correctly.

Final question is how can I test the gauge, stabiliser & sender to ascertain where the fault is. Or do I have to replace each until problem fixed confused

.... Thx

Thx Guys. Followed your suggestions to prove VS, gauge & sender OK. Got to the source of the problem, a leaking float in the tank.
