110 Shore Power

[FIVE2MH]

Sorry....newbie's silly question.

When connected to shore power, does the battery switch have to be in the "on" position for power to the coach, specifically lights and refrigerator.
If so, how does one know if we're not using the battery?

[Kevin & Judy]

No it does not have to be on, but if its off the battery will not charge,

Thanks for your quick reply. The lights in the MH don't work if the battery switch is in off position, but the display on microwave is on?
We are getting for a trip and wanted to get the fridge cold with shore power.
Thanks.

That is correct, the lights are 12 volt so the battery switch needs to be on for those. The microwave and AC unit(s) is 110v only and work only when connected to shore power or a Generator that provides the 110v through the shore power connection system. The refrigerator runs on 110v when on shore power but will switch to propane if it is set on auto so to run the fridge on propane the battery switch must be on because it requires 12 volt to operate the control board that runs to fridge and propane controls.

I'm not sure which fridge they put in the solera's but if it's a dometic like mine, then you need to have the 12v on to run the fridge, even on 110v. The 12v powers the control panel.

If you don't have lights with the battery disconnect then you probably don't have 12v for the fridge either.

This could be for one of two reasons:

1) your disconnect also disconnects the 12v side of your convertor.

2) the 12v side of your convertor is not affected by your disconnect and just isn't working for whatever reason.

If you're wired like #2, then you might have an issue leading to you ending up with a dead battery down the road.

Better to confirm now that your convertor' working properly.

On my 2014 24R the lights work if I am on 110 regardless of the battery switch position. Like others mentioned, you need 12 vdc for the frig control circuit.

Sounds like you are having DC power issues.

[FIVE2MH]

Oh, how do I check to see if the converter is working? I don't know where it's located!

BC could better answer that for you, but you can try under the kitchen base cabinets or near the hot water heater. Open the drawer above the hot water heater and look in the opening behind the drawer. Not saying for sure.

Look at item 21 in the attached file. Hope this helps! Note: this is a 24R.
There is probably a circuit breaker/fuse for the converter at the main power panel.

If you are plugged in to shore power, check the control panel battery level - all the lights should light when on shore power, indicating converter is charging the house batteries. If not all the lights are on (when pressing the battery button), check the circuit breakers. Our 2012 occasionally trips its breaker when I connect to shore power.

Thank you all so much. Jim just got home so we'll check out the suggestions!
First MH, and just when we think we know it all - of course we do not!
We are going to the FROG Rally in Tampa tomorrow....hopefully we'll pick up lots of good tips and information!

Thanks again....be safe forum friends!

Depends. We started wiring direct to the batteries with the Progressive Dynamics converter. So if you have that, it won't matter. Charges all the time.
