Guardian model 0055040 17kw, This was not used for a couple of years and the battery had been removed, I installed a new battery and it will run manually but there is no display and the escape, enter, -,+ buttons do anyhing. any ideas on what to do to fix this? The fuse is fine.

The screen may be bad. It was not uncommon to see the LCD screens on the older 0H0643 control panels go bad. If the battery is fully charged (I assume it is since the unit will start normally) I'd say that's what's going on.

The newest version of that panel can be seen here: https://shop.gentekpower.com/products/g ... trol-panel

Thanks for the quick reply, I am going to look to make sure everything under there is plugged in and will get back to you. Do you have any idea what it cost to have a tech check it on site? I would hate to put that in it and not have it work, and yes it is a brand new battery that was fully charged before being installed.

If the unit starts and runs, that means the controller has power and it's very doubtful that anything else would cause the screen not to work. Generac service prices vary wildly so I cannot say for sure unless you were in Michigan in our service area...
