I wanted to test the fuel sender in my van, so I hooked up my multimeter to the two posts at the back of the fuel gauge that are the input terminals to the gauge - thinking that this would allow me to measure the current or resistance that the gauge measures. Well, it seems I've missed a very obvious electrical principle because as soon as I hook up the multimeter and turn it on, the gauge will drop to "E." If I turn the multimeter off, the gauge goes back to where it should be. What am I missing here? Should I be testing the sender from somewhere else? I want to determine the range of resistance or current that maps to a full and empty tank. Todd '88 Westy |
