2 gauges quit working

[southdakota85chevy]

both my gas gauge and my temp gauge are now suddenly reading too high, from what ive heard it could b caused by the voltage regulater in my alternater, but my voltmeter seems to b ok and it charges fine, guess im not sure what to think

Have your alternator tested, many auto parts stores have the ability.

Then check your dash grounds as well as the printed circuit board on the cluster.

If they both started acting up at the same time I would start at the cluster and clean your connections at the printed circuit.

alternator tested out fine, geting frustrated, were are the dash grounds located?

[zieg85]

If I were a betting man you are going to find a burnt spot on your printed circuit board on the back of your instrument cluster.  I had mine go out, a quick trip to the pick-n-pull and $35 lighter in the back pocket I got a nice one that had a quartz clock.

As you've heard us say - CHECK THE PRINTED CIRCUIT

[Irish_Alley]

the printed circuit has a ground and everything else it should be the problem as vile keeps saying lol

[southdakota85chevy]

well printed circuit seems to b fine, cant find any problems there..., think im guna hav to break down and take it in to someone who can do a ltl more testing than i can, frustrating

[Irish_Alley]

make sure your ground on the circut board is good use a ohms tester and test the plug ground then plug it in and test the gnd on the board make sure they both read good
