Hope someone might have a thought before I purchase a new board. I have confirmed 240vac at the generator and I suspect the board or component had gotten fried. This is an 11kw air cooled. I am unsure where exactly the surge got onto my lines but a few breakers in the house did trip. I was not home but I do not think the generator tried to run, it was in setup mode like when I originally installed. Date data, etc.. was not retained. If I put it in auto after the delay it starts, I have not let it run long enough to see if the transfer switches or not.

Thanks!
Chris

Check the voltage with some type of load and not just a digital meter. A Wiggy style meter will apply a small load to the lines which may reveal a bad fuse that a digital won't catch.

What's the serial number on the unit? I assume this is an Evo 1.0 controller?

Thanks Chris,

I was pretty certain the voltage was the real deal but I threw a starter on the terminals at the generator for kicks and giggles.

That is an Evo 1.0 unit, so this would be the controller for it: https://shop.gentekpower.com/products/g ... trol-panel

LOL, a 240vac contactor for fans/heaters/etc.., pretty common in hvac split systems, just grabbed what was on the truck.
Thanks, I saw the part on your site, I assume then that would be your next step, will get it ordered?

Haha, sorry I didn't realize that's what you meant! :ahh: I would say that's the logical next step. If you have power all the way up to the controller and the controller isn't detecting it, that makes me think the surge/strike probably smoked the PCB inside :sad:
