Re: Fuel gauge reads empty

I had a fuel tank sender go bad on my previous boat. They are all pretty standard. The sender is just a variable resisitor. It changes value as the float goes up and down. The gauge and sender and just in series across the battery. Voltage across either should be somewhere in the middle between 0 and 12 volts.
