My 1995 31 Open has 2 sets of gas gauges - 2 on the dashboard and 1 on top of each tank. Both sets stopped working recently and I have idea why.

Any suggestions would be greatly appreciated!

Thank you,

I would look for a bad negative connection at the tank . The black wire, not the green one. It is probably daisy chained to the the second tank. The green wire is for bonding and no circuit current should ever flow in it. A second common point would be +12 volts at the dash but I would expect other problems also if it were bad.

Thank you very much. I'll check the connection today. I don't understand your comment about +12 volts at the dash, but hopefully the connection is the issue.

I appreciate your advice to me as well as the advice you have given others on this site - very helpful to newbies like me!

+12 volts turns on at your instrument cluster when the key is in the START / RUN positions. It feeds all the instruments, not just the fuel gauges so I doubt the problem is at the dash or you would see other problems.

I have a 1989 2700 and fuel gauge stops working or bounces up and down anyone know why this would happen

Ground wire.

If you search my old posts on here, I believe I created a post on troubleshooting fuel gauges.
