Fuel Gauge Just Went Stupid

I just put on a new R/R and thought I had solved my electrical problem. I took the bike for a ride and noticed the fuel gauge was at the half-way mark. In a few miles it dropped to a quarter. Then went back to a half then went to the mark just above the red E line. This was all in the space of about 15 miles. I stopped to fill up and only needed 1.66 gallons (and I fill it to the top). Never had a problem with the gauge before. What should I try?

Check the electrical connection that comes from the tank's fuel level sender. Make sure it's nice and clean with electrics cleaner, and pack it with dielectric grease.

I agree with tanner about using dielectric grease to seal the connector from moisture and prevent oxidation.
Just remember that dielectric grease is an insulator, and the connector needs to fit tightly so the grease is forced out from between the metal contact surfaces.

Make sure you are not reading the gauge while on a hill. I can bounce my front end while holding the front brake and watch the gauge bounce. Just a thought for you to consider.

and always remember, "Ride until you rot!"
**Really not sure if the Big "C" is back right now
but having to face the fact that this is a lifetime routine
going forward. Five operations done and it still continues.

That seems to have been the problem. I sprayed contact cleaner into both parts of the connector and now the gauge works fine. A simple fix. Thanks for the suggestion.
