New(bie) Owner Flair 29M (2021) VERY CONFUSED

[JKVECTORS29M]

Just purchased from private party 2021 Flair 29M. I have several questions.

1) When hooked up to 50amp shore power, if i read the manual correctly, I
STILL have to have the AUX Battery ON to run the coach lights and AC. Is
this correct?

2) What is the RED BOX (ON/OFF switch) located next to my inverter in the below storage area next to the door?


a) when hooked up to shore power
should this switch be ON or OFF?

b) when driving down the road, should
this switch be ON or OFF?

c) when generator is RUNNING, should
this switch be ON or OFF?

The only thing I was told was that when I store the RV the switch should be off... Is that even correct?

PLEAS HELP>>> VERY CONFUSED

THANK YOU

Congrats on the new rig! It may help if you can post a pic of the "red box". Have fun and keep her between the ditches!

Good luck, happy trails, and God bless!

On at all times and off for storage if not plugged into power. It is your battery on off switch

[JKVECTORS29M]

Thank you for the quick reply.

So to verify : OFF when in storage with NO power....

On when driving....
On when at campground HOOKED UP TO POWER....


How about when hooked up to 110v the night before i leave to cool refrigerator?

Also if boondocking with generator ON, should the switch be ON or OFF?

Thank you again for your time/input.. much appreciated

The “big red switch” connects the batteries to the inverter/charger. Only have the switch OFF when in storage without being plugged in. If the coach is “in use” (plugged in or driving) have the switch ON.
The inverter has a residual drain on the batteries if left ON when in storage without being plugged in.
After you “ plug in”, you may have to manually “turn the inverter ON” so it will operate the refrigerator.
You need to go to the Magnum web site and read the owner manual for more detail on the operation of your inverter.

You didn't mention whether or not the manuals were provided with the motorhome. If not, they should have been. If not present, you may be able to purchase whatever manuals they may have for your coach. There should be one for the chassis, one for the coach and assorted manuals for other installed equipment items. Now a personal observation regarding the manuals. As a retired senior publications engineer I wrote, revised, updated and otherwise managed an extensive variety of manuals, specifications, proposals and more. The point is, I read my motorhome manuals with a red pen plus a tablet to make notes. All RV manuals that I have read may have missing or faulty information; may described one or more items of equipment that either are different or not installed; or not mention installed equipment. Last year we bought a used 2020 Fleetwood Pace Arrow. The manual explained the use of a battery cutoff switch, didn't illustrate it, didn't identify location. An RV mechanic and I performed a diligent search and finally determined that no battery cutoff switch was installed. The same manual describes the macerator toilet that is installed but that is not what was installed. A manual for a company-installed telephone booster and WiFi booster explained how to install it but not a very good explanation of what it does and no explanation of how to use it. The point is, you need the manuals but they are not perfect and even if the RV manufacturer is told about the problems no change pages will ever be issued. Manuals for the aerospace industry have to be as perfect as possible and I have written many change pages to replace pages in a binder. When equipment was upgraded it was not uncommon to produce a revised manual to replace the previous edition. If willing to pay for it I read that Freightliner can produce a manual for a specific revision and serial number of certain models.
