Gauges acting odd

67 Coronet.. Everything new or rebuilt...

Temp gauge was running a little warmer than usual the other night.. Checked water level, fan belt tightness/possible breakage, everything OK..

Happened again and I notice ALL of my gauges ( Voltage, fuel, and temp are all swinging to the right a couple of needle widths more.. As I drive along next look at the gauges, all are acting normal.

As said above, rebuilt gauges by redline, all new wire harnesses, electronic voltage regulator....

Any thoughts on here?? TY

electronic voltage limiter on the instrument cluster? I'd check/clean all connections starting with the bulkhead

X2 with Robert. Too much voltage passing through gauges. Find the fault before they fry. Get another Voltage Limiter.

or if it is "new" consider replacing the instrument vr.
some of them have been known to fail high and eat gauges.

The voltage limiter was supplied by Red Line when they rebuilt the dash.. Probably 10 years ago..

Any recommended suppliers of these?

personally I built my on solid state one based on the tech archives.

but a couple of people supply them on the board.

Update as reported in my other thread, the new voltage limiter seems to have solved it, plus improved the brightness of the dash workings overall.. TY to everyone
