Voltage Meter Fluctuating in 2001 Silverado 3500
I have a 2001 Silverado 3500. After a
usual day of driving (20-30 miles, no I
don't drive a lot lol) the voltage meter
will read about 15-16 volts like the
volt meter should while driving. But,
now it after few minutes of driving,
the voltage meter will drop down to
about 12-13 volts and sit there
slightly wiggling back and forth.
What could be my problem here?
Thanks for any advice given.
Check the big red wire that comes from the battery to the power distribution box, if it looks bubbled close to the battery it has corrosion inside it, you will have to cut it all out and solder an shrink wrap in a new piece of wiring.
Big red wire coming from the battery to the distribution box looks fine, not bubbled anywhere.
Try bending it slightly, listen for crunching noises, if it crunches then there is corrosion inside.
Sorry bout the late response. But I tried bending it like instructed and no crunching noises were heard.
Ok then I would suggest getting an add on voltmeter, some will fit right into the power port or lighter and monitor the voltage with that for while. It is possible that you have a stepper motor starting to fail in the instrument cluster or bad connections in the cluster IC board.
Okay. Thanks. I appreciate the help
