Very often this can be caused by a faulty ignition switch Monitor the voltage at the fuse "IGNITION 0" for charging system voltage. If the voltage drops below charging system voltage, check the Maxi fuses under the hood.If the small fuse is low voltage and the Maxi fuse is OK voltage, replace the ignition switch
I have checked the voltage and both fuses read 14+ volts. I have checked all the connector under the dash. neither gage cluster works properly I only get readings occasionally, usually asfter a bump in the road. I did see a change in the gages while I was pulling my tractor/trailer.
I will gladly paid again if you think you have an answer.
