2016 DX3 BH Dash Button

[DX3AZ]

Greetings DX3 friends. Always great to connect.

Today as I was cleaning my DX3, I came across a button on my dash, between the clock and the autolevel system. I pressed it and could hear a click, but didn't mess with it just in case. Can someone help me out and tell me what it might be. Picture attached.

Thanks!

Coach battery pass through. When your chassis batteries are dead you can get power from coach batteries when you activate this normally open switch. I’ve also used it vice versa when coach batteries are dead and I need to start the generator.

Thank you! I was wondering the same thing but hadn't gotten around to asking yet

as a Momentary switch, it is likely your AUX (BatteryBoost) which can be used if the engine is laboring to turn over, the generator struggles to start, or the slides or levelers aren’t moving as they should - basically tying together ALL the Chassis and House batteries at the same time... it’s a great tool to have : )

Thank you all for your input. Now I know. Luckily I haven't had this issue yet, but good to know I have this backup.
