    Good day to you all, fellow drivers!

    I've got Cascadia 2019 with Webasto bunk heater. Every time I turn it on, couple hours later my 3000 watt Power Inverter shuts down. The only thing that plugged in is a fridge. Does it mean that my batteries are too weak for Webasto + fridge combination?
    Another concern is - shouldn't engine start automatically, when batteries are drained out?

    How old are your batteries?

    The Webasto doesn’t draw a lot - the fridge is more of a drain.

    Only time I had this problem was with weak batteries - have them load tested.

    Simple stuff first. Clean and tighten terminals. Check ground to frame.
