The fuel gauge is telling me the tank is always empty. Using the traditional wooden-curtain-rod-dip-stick technique I find the tank is half full.

I looked in the manual and it said to test the gauge by removing one wire from terminal T. There are no markings I can see for terminal T so I assumed it is the wire that is not the power supply. At this stage, the needle should read full. I assume the tank sensor has max resistance when the tank is full.

The needle didn't move. I think I need to get the gauge looked at. Does anyone have any other suggestions, or can recommend an instrument repair shop in Sydney? Would appreciate any help.

More than likely earth in the sender unit.
Have a look at this link.

Checking and testing is really quite simple however If you are taking the gauge to someone he will probably want the sender unit anyway.

I would prefer not to have to pull out the tank if I can avoid it. Did a resistance check between the sensor wire to the gauge and earth and used a wire hook to lift the arm. There is a change in resistance as the arm moves, so that would hopefully point to a functioning sensor unit. It should also indicate the tank is earthed.

Spoke with Paul. He was just pulling out of Derby WA and won't be back until mid-August. Bit far to go to get him to look at it.
