I have an erratic readout of the fuel and temperature indicators on my '84 GL. Every few moments the dash beeps and the readings change drasticly. I heard somewhere that there is a resistor in the dash that is common to both of these functions and can get flaky. I have tried to find such an item but without luck.

 

Any help will be appreciated.

First of all, make sure your alternator is working correctly. A beeping from the dash means its getting a voltage spike, it also means your dash is a few spikes away from death.

If the alt is ok, check the contacts on the back of the dash and if your feeling real brave, open the cluster and look for bad contacts too.

Turbone,

 

Thanks. The beeping is the same as when you change settings on the computer/clock, momentary and at the same instant that the display changes.

 

The alternator did just die and was replaced but the flashing/beeping continues.

 

Today I pulled the cluster and looked at as much as I could (without schematics). Tomorrow I will put it all back together and see. Everything looked healthy. No evidence of heat or weak/cold solder joints.

 

Thanks again, RW...

better have the alternator tested. It might have been just replaced BUT you can still have problems with new ones as well.
