The power switch seems to operate backwards. When I turn it off, the switch is closed according to my meter, and I get .02 ohms, basically a short. When I turn it on, the switch is open according to my meter. I know this sounds like I'm doing somethong wrong. I got it once ot twice to show an open when the switch actually was open and when it was closed it read 40 ohms. I'll give it a spray with some contact cleaner, maybe that might help things.

Secondly, the excessive current draw. The primary winding reads .6 ohms on my meter, which is the DC resistance it should be according to the service data. When I plugged it into a surge protector, the plug vibrated and the lights dimmed. There is a short somewhere on the secondary side of the transformer. I think I wired the electrolytics wrong, infact I'm almost sure of it. What I'm curious about is why didn't it draw that much current as to pop the breaker? I'm not sure if the surge protector limited the current or it was the limitation of the transformer. It was odd and something I never experienced before, so that's why I'm asking about it.

Thanks.

Jonathan
