W22 no chassis power

[Noleakman]

I have an 06 Sea Breeze W22 and when i go to start nothing works including the steps! Battery is fine If I push the boost switch and let go of it with key in ignition everything light's up and it will start with my hand off the boost switch!It will seem like it is ok and then next time same thing ! Is there a solenoid the is bad? I wonder why everything works when I push the boost switch but I don't have to hold it in I just push and let go and everything is fine then it will start

What makes you believe the engine/chassis battery is fine? The fact that the steps do not work is a big clue that the chassis battery is not OK. If the boost switch overcomes the problem the solenoid is probably OK.

I have an 06 WH chassis and just found out the chassis battery is toast. Will be getting a new one very soon.

The battery shows 13 volts with a load tester and only goes down a little under load test but what I can't understand the the gauges in the hall show nothing for the chassis battery 0 and while running the generator it still shows nothing I don't get it

NRV steps are powered by the chassis battery.
