1973 Series III 88
My fuel gauge suddenly stopped working. I've been through all the fuses and they seem to be okay. I uncapped the cover plate in the passenger seat and am now starting at the (nounted) sending unit and the connecting wire.
Before I bust into the fuel tank to replace the sending unit, I thought I'd best test the wiring to the panel, and perhaps test the sending unit itself. Problem is ... I don't quite know how to go about this, as I'm unclear exactly how a sending unit works. Should I simply be receiving varying voltage levels based on the fuel state? Since there's a single lead, how could I send (or receive) a power signal from the sending unit to confirm that it is or is not working?
Thanks,
Don
