RE: Need some electrical help.

Manny,

A couple things in addition to what jea48 and stereojim have instructed:

1) If you connect the transformer leads directly to the IEC filter unit, the power supply will be constantly on whenever it's plugged in. This is your choice, of course, but if it were me I'd put a switch in there.

2) IEC input filters like the one you have are typically intended to have the wiring connections made with a slide-on connector (ie: stake-on terminal) rather than have anything directly soldered to them. Be aware that if you solder the transformer (or switch) wires directly to the IEC, you may melt and dislodge internal connections inside the filter depending on how it's constructed inside.

3) The center lug on the IEC filter should be the earth (or safety) ground tab. I strongly 2nd jea48's suggestion though to continuity check the filter from end to end and make sure the center lug matches up with the center pin on the other end. In any event, this ground should be connected to the chassis or case of the unit. This will prevent the case from being live if something is miswired or there is an internal fault or failure with the unit.
