gas gauge

[DBSTTN]

the kid tried to connect the battery with the ingnition on,,,the garage said that sould not have hurt the gauge or sending unit,,,gas gauge stopped working and speedometer off by 10 mph....
I discnnected the battery to reset the computer, the speedometer corrected but the gas guage still doesnt work,,,,,,
any good tips??????????about relays or hidden fuses anywhere

Is it innacurate or just not working? If it's defunkt, it may be a fuse. But usually ignition on or not, that (in theory anyway) should not affect the dash instruments. It's not to different then "suddenly" turning on the key from a electrical standpoint.

My 96 regal fuse block is located next to the glovebox between the dashboard and passenger door. There is also a couple high amperage fuseblocks under the hood close to the wheelwel. But that is for headlights, charging, and similar systems. I doubt there would be any "hidden" relays, but if their are, they'd be behind the instrument cluster. Most fuses and/or relays are all together execpt for the high power systems I mentioned.

I have checked everything,,,,all it can be its the gauge or the sending unit,,maybe the ground on the sending unit..tomorrow I and putting it on a machine to chech continuity,,,hope it is only a groung....
guage cluster is 250, the sending unit and fuel pump is all in one and runs $350
