Store/Use "Click"?

[Philm1]

What is it I'm hearing go "click" when I flip the switch from Store to Use? It's somewhere in the RV but I can't figure out where it's coming from. Thanks.
Oh, I have a 2015 ACE 29.2

That is the latching relay that is disconnecting (or connecting) your coach batteries...

 

[MrPalazzo]

it controls a Solenoid which provides the attachment to or release from battery power

Most likely behind your power distribution (Breaker/Fuse) panel.

Essentially: you need to start worrying if you don't hear that click...:nonono:
