Fuel Guage issue....

[Jayco36REQS]

Anyone have a decent troubleshooting flow-chart on Fuel guage issues? Mine is pegged at full.
So far I've checked:
- Guage ground
- Tank ground
- Top of sender ground,

When I remove the gound it jumps WAY past full.....

Thoughts?

I have the same issue. Tank is always full. I was able to get my arm in the fuel tank and move the float up and down. So the float is not stuck.

The new Tm 23 series has great flow charts.

What you seek is in TM 9-2320-272-23-1 WP0107 (work package) pg 905-912

See this thread about them and where to download.

Best of luck and post your results so others might also gain insight.

I put an ohmmeter on the sending unit and got no change in resistance when moving the float arm up and down. Based on this, I assume the sending unit is bad.
