Buy a new ATS and be done with it.  

Up to you whether you buy one with built in surge and power protection. The argument for a combined unit is less total cost and less wiring. The argument against is that if the ATS and power protection are separate units then if you cook the power protection system you can bypass it and still have power. Dealers choice.

I have a agree Richard.  I was contemplating using a manual switch instead and get rid of the headache of boards burning out but I think I will go ahead and replace what I have with an ATS... I like the idea of having a separate power protection unit so will be going that route.  Was hoping that Camping World in AL would have one but they have to ship... will probably just order from Newell.

i made this schematic when i worked on mine. (sounds just like yours)
