Fuel gauge sending unit

[cybindustries]

Does anyone have a source for the tank sending unit mine appears to have died on me. Gauge pins past empty when main switch is turned on.

Do military fuel gauges ever work? I trust them as much as I trust politicians, either way.

I have a spare new one. Could be a bad sender disconnect it and short the 2 harness wires see if it pegs full.

Ill try that tomorrow thanks Superman

All my LMTV fuel gauges have red low.. At empty there was still about 15 gallons left.

Yes I agree. Same with mine. I call it "reserve". Gets me least 4 more miles closer to the gas station HAHAHA! I carry a stick also to check.

Mine read low also until something went weird with the wiring. Then it just pegged below E. The sending unit tested good there is an issue between the sending unit and the gauge going to track it down this weekend.

Do all your gages read a bit low? Maybe low voltage at the dash for some reason.

For anyone looking here's an option for a new sending unit. I got the 15" version and it bolted right in. Only thing I had to do was solder on the connector. They do make a shrouded version like the original but I went with this one because it was available. I bought mine off Amazon but it looks like this place sells them too. http://www.duskyonline.com/WEMA-p-fuel-senders-withdraws.html#prod-chart

cybindustries, did you ever figure out what was wrong with your fuel gage that was pegging below E ?
I have 2 machines doing the same thing, an 803 and an 802. I know that the problem is being caused by the sensor wire's circuit going open at the gage, but haven't had time to test anything yet. Looking at the schematic I believe the sensor wire goes to a terminal block ( which I think must be located behind the wall, in with the guts of the AC reconnect switch ) so I have to remove the cover to access it.
The 803 seems to be an intermittent problem, so with any luck, maybe I'll find a bad connection somewhere.... On the 802 I don't know yet. Haven't looked into it at all yet.

Sorry guys, I googled my genny fuel gage problem and didn't realize this wasn't in the Auxiliary equipment section....
My bad... I'll go look in the right section now!

What capacitance value does it have (10-180 or 240/33 ohm)?

240 to 30 ohm.
