RE: [Chrysler300] 300F gauges won't work - what should I do?

["Krikhaar, Alex" <akrikhaar@xxxx>]

Seeing Bill's excellent reply to Frank regarding his c300 instrument panel
encouraged me to throw my 300F instrument panel question in.

My astrodome panel lights up alright, but since I got it back from my
mechanic the gauges no longer work. No reading on the speedometer either.
Does anyone know what would be the correct order of things to check before I
crawl under the dash? I'd rather do this myself than having my mechanic
possibly make things worse...

Frank,

Under no circumstances would I try to put a full 12 volts to the 
gauges. 12 volt MOPARS use a voltage regulator that provides a pulsed 
voltage to the instruments. The effect is to have a lower mean voltage, 12 
volts will fry them in short order, plus they will be inaccurate since they 
are not calibrated for that voltage.
