Not much of an auto electrician. Was after some help please. When I turn my ignition on, I get a reading from my fuel gauge. (Built into the big central speedo) Once I start the car, the fuel gauge drops back down to zero? I assume it may be a grounding issue somewhere. It may have something to do with the installation of the second fuel tank? A nudge in the right direction would be much appreciated.

Check your earths, could possibly be the voltage stabiliser, which is mounted on the back of the speedo, ( its a small rectangle metal canister with 4 pins coming out of it ) I doubt that the second tank would have anything to do with it. I had a problem with the voltage stabiliser in my car ,where gauge was only reading half full, also the temp gauge would only read about a quarter, changed it and now they both read normal, but in saying that ,every now and again both gauges decide to not work and they drop back to zero. |

Check your fuses and also make sure everything else that works of the ignition still works like Indicators, Stop lights ands wipers. Mighty be a fuse box problem. Measure some voltages at different points. |

I bought a voltage rectifier from MiniSpares. So old problem was ignition only on, fuel gauge fine. Start the car, fuel gauge turns off. I installed the new part, which only has two terminals, B and I. Now the gauge doesn't work at all. Have put the old one back in for now. Any ideas helpful people???

Any ideas helpful people??? They are a 3 terminal device. You need to Earth the case. B is +ve and I goes to the gauge. |

Will try the new one the other way around. Cheers. |
