I've noticed there's been a lot mentioned about faulty fuel gauges on Jeeps, but I couldn't seem to find what I was looking for in the archives. In my '89 YJ my fuel gauge reads =BC tank when it's about empty and way over full when I top it off. Anybody out there seen this before and know what needs to be fixed / replaced before I go and do something unnecessary? Thanks

I have seen this problem before and I have it now.
This could be either a grounding problem back to the sensor in the gas tank, the internal gas tank levelometer or the cluster itself. However, mine is a 93 and we are therefore cousins of a kind. I moreover suspect the instrument cluster is hurt because of a water leak. I lost my speedometer and my first instinct was to replace the transmission sensor. I later disassembled the dash and found the interconnect film was corroded and connections were open. Daisy stepping with a soldering iron and I got that instrumentation back.
Personally, I will be replacing the cluster on my vehicule when I get the time. When I had the battery disconnected, the meter still would not zero. The movement is most likely hurt. It is a terrible inconvenience, I know. However, if you are familar enough with your vehicule's fuel economy, watching and resetting the mileage log after refueling is a work around (for now).
