The weird thing is it's sending the empty signal... Wouldn't it have no resistance at all (open) if the wire were worn through? Is there any way the float could have fallen off?


You got your terminology mixed up, an "open" is infinite resistance. If I remember correctly empty is higher resistance and full is lower resistance so the symptoms make sense. An open should show infinite resistance, thus the empty signal.



Yeah, my terminology is rudimentary at best.

So infinite resistance would be probes not touching on the multimeter? And zero (or very close to) would be just touching the probes directly to each other?

The reason I'm wondering is this:

The FSM lists resistance for 'full' as about 3 ohms, and 'empty' as 110 ohms. To me, if it did break somewhere along the wire, there would be infinite resistance because current couldn't flow over the circuit, correct?

When I hook the probes across the pins, I get about 110 ohms, which is the empty signal, which says to me the wire isn't broken, the arm is just sitting at empty. Either stuck or missing the float.

Does that make any sense or should I just stop trying to comprehend electricity? <img src="/forums/images/graemlins/lol.gif" alt="" />
