Question about Chevrolet Tahoe
I have seen this in several different GM models....there may be the possibility that the ground connection from the battery is defective....you can check the ground connection coming off the battery...there is one that goes to the engine block and one that goes to the body of the car...the body ground is usually the culprit...make sure the wire going to the body is good(or even there)...if you don't have a wire there(or it has broken off) you can add one to the ground post of the battery and then attaching it to a place on the body...a good place is where the fender attaches...you can put a ring type crimp terminal on the wire and take out the fender bolt...put the ring terminal through the bolt and re-attach...another possibility with some GM models is the instrument cluster plugs in to a plug on the dashboard...there is the possibility that the connections on this plug have become oxidized and that the cluster is not making proper contact...you can remove the cluster and try reseating it to see if this solves the problem....and finally, there may be the possibility that the voltage regulator in the alternator is going bad...the way to check this is to obtain a voltmeter and check the voltage on the battery with the car running....it should be around 14.4-15 Volts DC...if the voltage is around 12.5 - 13 Volts DC with the car running, then the alternator is not working and therefore not charging the battery or providing enough voltage in order for the gauges to work properly
