All gauges pegged out-66 Coupe only after I replace a couple of bulbs.?

JAO · 02-28-2006, 08:12 PM

All gauges were operating fine. I eased back my instrument bezel and replaced a couple of burned out bulbs. Put it back in and my fuel, water temp, and engine temp gauges peg out. I've followed the ground from the constant voltage post to the frame under the dash- it has continuity on the meter- seems to be fine. Any trouble shooting advice out there?

Yeah trouble shooting under the dash is not alot of fun. I would check that no other bulb has come loose and is touching one of the gauges. You will propably need a manual to look at the wire diagram. Double check your constant voltage reg that what you have coming in is coming out. Check you connections at the gauges in the back to make sure none are touching and all are in tight. Check your main connections for the bezel that all connectors are tight. If all checks out you may have to remove the bezel and meter out each wire to what has happened. Hope this helps somewhat.
