battery gauge

[catsgalore]

We have a 1999 Fleetwood motorhome. Yesterday while heading out the battery gauge on the dash showed red. The battery is perfect, the alternator is good and charging, house batteries are good. Yet the gauge will not budge. All wiring has been checked as well as the fuses. Can you help?

Buy a cigarette lighter battery gauge (-$20) for your trip to check existing gauge.

The battery and charging system were checked out by a RV mechanic with a meter. He seems to think it is a dirty wire somewhere. We planned on taking a long trip and this is a little unsettling to me.

Have you connected a digital volt meter to it and to verify the voltage? If so and the voltage is fine then the meter is junk - but I doubt it.
More than likely you have a real problem with the battery or charging system because volt meters are very simple things and don't fail often.

How do you know the battery is perfect? How do you know the alternator is charging? How do you know the house batteries are charged and good? If you are using a good Multimeter to determine what you post, then it is obvious that the red battery gauge is BAD.

The gauge has failed?
