Can I replace my Forester circuit board?

[Cyberstork]

Looks like I need to replace the circuit board that is in the box under the panel in the stairwell of our Forester (2017).
It seems like I should be able to replace this myself if I detach house battery (neg connection) unscrew two screws and one nut. And then carefully (based on photo) replace all connections as they are now. Or, is it more difficult than that?
Any special cautions?
And then, where can I buy a replacement panel online? I can't seem to locate one. Not exactly sure what to search on.
Thanks,
Dan

I don't know of any special tools required when doing this sort of work I unplug from shore power and disconnect both neg and positive cables (maybe not required but something I do) I would reach out to FR and see if they will supply the board or point you in the right direction to obtain one.

Your going to want to disconnect the positive battery cables from both the house and chassis before removing the board. The risk of arcing either to ground are high. Each of the terminals on the isolation solenoid connect to one of the batteries. Precision Circuits has a document explaining how to remove the board.

Why do you need to replace the board?
