Onan generator and gauge

the gauge is bad have the same trailer it should start to move after the first 5 gallons is put in

on mine you have to push a momentary contact rocker switch to make the gauge move.

you could check the connection points (back of switch and sending unit on tank)

if everything all tight then one of 3 things
- broken wire
- bad gauge
- bad sending unit

if it were me; i'd add it to the list of fixes for the warranty claim to happen after you get a few trips under your belt; i'm guessing you'll find some other surprises along the way

Gauges are lit up, I turned switch on that works the pump for fueling,Also turned off all power and ran generator gauge still reading empty.It worked when wife first picked it up and put fuel in it,has'nt worked since, only had it 3 weeks.I;ll check anything.

Do you have a switch which "power's on" the fuel system; does that run the gauge as well?

Can you tell if the gauges have power? Are they backlit?


on my cyclone the timer switch only lights up the fuel pump; the gauge for the genset is always active; but maybe yours is different

Mine was broken when I first got it (and it's still a little funky) but at the factory, they reversed the wires. Check that....
