Topic: Transfer switch for a 2023 MBL (Read 822 times) previous topic - next topic

Hi everyone, we purchased a 2023 Wonder MBL and I think I damaged the transfer switch. I plugged my shore power into an extension cord and into a 15 AMP plug thinking I was setting up a trickle charge for the batteries, like I did for my Thor ACE. After a while there was a loud thud like noise around where the shore power inlet......then it stopped. The generator still powers the cabin and charges the batteries fine but the inverter readout doesn't show swithched to shore power any more. Does anyone know where the transfer switch is so I can check it? Also, does the shore power plug have any kind of a circuit breaker. I checked the main circuit breakers in the cabin and they are fine. Thanks for your help....it's an adventure!

I can’t help on the location, but if you are registered as an owner on LTVs website, the manual should be downloadable there.  On the RL it’s under one of the jump seats, but the MB is very different.  I think the transfer switch has a reset if I remember right

Have you plugged in to a different outlet?  I would expect you to pop a circuit breaker on the circuit breaker you were plugged into at the house/outlet, I would check that.  If you are lucky, that popped and the sound you heard was power turning off at the transfer switch.  I’ll cross my fingers for ya!  You can also try just cycling power with the main switch.  I always try the easy stuff first.

I think there is a way to limit the input power on the inverter so you don’t pop breakers, check the manual for that.  We’ve switched to a Victron so I’m no help there either.
