I have owned this RV for about three months. I have noticed that when switch to Aux Off, it should turn off the carriage lights, etc. It does nothing. I have looked at and checked the solenoids and they click but don't turn anything off. I have looked at the Winnebego skematic - not much help. Does anyone have more info on this?

Don - I think you may be misunderstanding the purpose of that switch. On some coaches the AUX switch is used momentarily to connect the coach batteries to the engine battery, so you can start your engine should the engine battery go dead while camping. This is done with a solenoid that connects both the battery systems as long as the switch is depressed. So, if you ever find yourself unable to start your motorhome because the battery is low, simply depress and hold the AUX switch while cranking the engine. The starter will then get its necessary power from the coach batteries. Once the engine starts, release the switch and let the engine alternator recharge the engine battery. Good luck. - Dave

Hi Don:

Interested that RVA Dave mentioned the Battery Boost switch that is on most Winnebago rigs.

I also have an Itasca (built by Winnebago), and the Aux Bat switch at the bottom of my entry door does indeed turn off almost all of the 12V circuits inside the motorhome, all the lights, propane monitor, etc.

Not sure why it isn't working correctly on your rig.

Not sure how far back the Winnebago web site goes with wiring diagrams, but you might take a look and see what you can find on your rig.

Cheers.


Cheers and happy travels, Mike www.backroadtravelers.com

Hi Don, again:

Just took a quick look at the Winny web site, and here is a palce to start on looking at what is available for your rig:

Don - As Mike correctly pointed out I was referring to the Battery Boost switch, which on my MH is on the dash and labeled BAT. If you're referring to the switch by the door, then that is the battery disconnect switch and should disconnect the battery from the coach, shutting off the 12v circuits. I wondered if my converter, when connected to shore power, would continue to power those 12v circuits when the batteries were disconnected. I just checked mine and when the batteries are disconnected the converter won't power those circuits. But, we've learned that no two rigs are wired the same, so if you're connected to shore power you might try disconnecting to see if your battery switch now works. Good luck. - Dave
