View Full Version : Fuel Gauge Help

I really am at a dead end on my fuel gauge??? I have a 2001 Prostar 209 and the fuel gauge just stays on empty. I have replaced the sending unit and the gauge with no luck, gauge still reads empty? Anyone have any ideas... I am not sure what's left? Wire? Brain Box? (but all other gauges work fine)

Anyone had somthing like this with the medallion gauge system?

I suggest troubleshooting the wiring. First, resistance from the guage to the sending unit. Then test the sending unit for a change in ohms as you move the float. Apply a load to the guage to check for function. You are trying to isolate where is the failure in the flow of electricity. Isolate, or check one thing at once.
