House battery charging problem...

This in re: to a 2017 Winnebago. The coach had sat for a few weeks and when I went out to move it today, the coach batteries were dead. It has been constantly plugged into a 30A receptacle. In addition, I had left the on/off 'salesman's switch' in the on position. Isn't the inverter or is it converter supposed to keep the batteries topped off when a/c power is provided thereby preventing discharge? Or, should I have left the on/off switch in the off position? Thanks for any advice. BTW, it's under new veh. warranty but thought if something simple or that I'm doing something wrong, advice from you knowledgeable members might save me from a 60 mile round trip to CW.

    How did you determine the house batteries were dead? Did you check them with a volt meter? If so what was the reading? With the MH plugged in take a reading across the pos and neg terminal of the battery, you should read something greater than 13 plus volts, if so you know that your converter is working. Unplug the MH from shore power and check the voltage across the pos and neg terminals, the next day, you should read about 12.6 volts if battery is good and connections are good. If you do this simple test and post your results here I am sure your issue will be solved. If everything was good when you bought it and this issue just happened in the last several weeks it is probably something simple.

    FIRST, Open and check that your SWITCH called the "Battery Disconnect Switch" a big RED knob is set to COACH power? Next, check Battery with an AMP meter to see if you have POWER and above 11AMP to start the RV-engine. NEED much more feedback. This is all a guess also have you ever lost power in the same batter prior? Next, in this FORUM go to the top on left and click on RVING FAQ Lots of good information for newbies: Check out YOUTUBE for "Battery Disconnect Switch" RVing FAQ

    on my RV, it has a Magnum inverter, on the remote control panel, you can turn on/off the charging feature.

    Even "new"...the converter/charger could be faulty. Under warranty? Take it back for repairs. CW ? Let us know how you make out..

    The chassis battery is fine. Problem only with coach batteries.
