Auxiliary Power Switch Shutting Off

by Gene W

Question: I have a 89 Winnebago chieftain. My auxiliary power switch shuts off as soon as I turn it on. Any ideas?

Robbie: If you are talking about your 12 volt auxiliary for the house, the batteries have to be above 10.6 volts for the relay to work (stay on). If your batteries are up and the relay is making a loud click when you turn it on, chances are you have a bad relay.

Hope this helps,
