Hi its a black fuel gauge even when the green and black wire is disconnected from the sender why does the fuel gauge go to full
Regards Paul

If it's going Full Scale with the cable disconnected from the Sender and not touching anything else on the bodywork, then you've got a short to earth on the wiring.
If you're not careful, you'll probably burn out the Voltage Stabiliser.

The Gauge on latter cars is a Bimetal heater operation, so for the heater element to be heating up, it must be earthing...


I've just looked at your history and seen that you've been asking about fuel gauge before...
What have you done between June and now...?
You've likely connected something incorrectly.....

Ever since I had the car (about 12 months) the wiring has been a nightmare its above my knowledge I will have to get someone in to have a look

It looks like there is a stray earth on the G/B between the Gauge and the Sender.

Thanks for your replys
