Fuel Gauge Stuck

[swhpaz]

I appologize if there's a thread out there already addressing this but I wasn't to find it. The ones out there are close but not close enough.

I have a M109 that has a fuel gauge that reads full all the time. I can't tell if its reading pegged, but its at the top.

I'm a fair mechanic, but suck at electrical. I don't have any of the maunals that deal with this specifically.

So can anyone help out here? Any ideas, suggestions, or plans?

I don't want ot spring for a new sender when its something else possibly.

Thanks to everyone out there!!! I do use your posts as a guide to finding and correcting other minor problems.

The same thing happend to my M109 on the fourth. I topped off the tank and now it is stuck at full. I put on over 175 miles so it should have moved.
