Should I Turn The Battery Disconnect Switch Off When My RV Is Hooked Up To Shore Power?

by Anonymous

I have a 1994 Fleetwood Southwind 35' Motorhome should I leave the main and Aux battery disconnect switch on or off while hooked up to 110 volt, for charging batteries. The battery is only 1 year old it is a deep cycle marine battery
I have been leaving them off and main battery will not start the rig.

ANSWER: Thanks for submitting your question on our Ask An RV Question Page.

Normally you should leave the Battery Disconnect Switch on when your RV is connected to shore power. Most RVers only turn off the battery disconnect switch when they are storing their RVs for longer periods of time and they are not hooked up to shore power to help eliminate drain on their house battery system.

As far as your Motorhome's starting battery is concerned it may very well be a bad battery or the charging system on the Motorhome itself that is not charging the battery. You should have your starting battery checked out, load tested, etc. You may end up having to replace the starting battery.
