10 Fuel Gauge Problem
Fuel gauge problem
I had a problem with the fuel gauge that was investigated by the same garage on a previous visit They
identified a circuit board that needed replacing but they did not have one. No problem, I thought. Will get
it done in UK. However, about a week later the gauge sprang to life by going to full when turning on the
ignition and then falling back over about five minutes to the correct reading. I can live with that so have
left it if it's working, don't fix it!

A dodgy fuel gauge on HoO3 GDP cost me about £70, as I recall because the circuit board is part of a
display which has the gear position, water temperature and oil levels as well as the fuel contents. Mine
used to go AWOL for shortish periods, but then packed up completely. I remember that when I shelled
out for the new unit, I had a sneaky feeling that someone with a knowledge of electronics might have
found the fault, though without the appropriate test gear, it might be very difficult.
