I know this has been addressed here before, but need to confirm a few things. I just picked up another K-250-4 and a new power cord was installed, but the guy who did it un-soldered all of the connections to the switch, so it does not light up at all. So I am assuming if I get all of the wires back in place like they were I will be OK??????I will snap a shot of what he did and post if that makes it easier to tell me.
