Winterizing the Electric

[Roger Rempe]

My Monterey will be wintering in an outdoor storage lot. For now, it has access to a 15 amp outlet. The lot owner wasn't sure if that will last. I don't think that there is room in the battery bay for two trickle chargers. So, if I step down the shore connection to 15 amps, then I have to leave the main battery shut offs on along with the inverter? Also, step down the Magnum control setting to 15 amp shore power?
If I don't have the electric feed, I'll have to rely on the solar panel. So, then I would shut off the chassis and house battery switches along with the inverter?
From what I've read, it's best to fill the diesel tank and not start the engine till spring when I can drive it. Assuming all is well with the batteries, I won't have to exercise the generator either? And of course, make sure the auto generator start is off.

If you leave the coach out in the winter weather, your batteries are susceptible to freezing, unless you keep them charged. Plugged in to 15A should be enough to keep them charged. I would still visit the coach (if practical) and run the generator with a hair dryer, or something that has a good draw, for an hour or so, at least once a month. That would also allow you to make sure a breaker for the 15A source has not tripped while you were away.

Thank you for the reply, Stan. Fortunately, I have AGM batteries so, freezing should not be a problem. Would you leave the battery shut offs on as well as the inverter?
