electrical type question - dead waveboxes

[christyf5]

So my second wavebox just packed it in yesterday. I have no idea what the problem is, I turned it off to do a waterchange and when I turned it on there was no power to it at all I took it apart and cleaned it but still no go.

Anyway, these things are made up of quite a few bits and pieces, the pumps themselves have some sort of little square thingy on the end of the power cord that the controller and the transformer both plug into. How do I go about checking to see if it is the pump itself or the transformer??

I managed to check the controller (even though there is a light on the transformer that usually indicates power) on another powerhead and it works (actually both of the wavebox controllers work). Currently I've jerry rigged the wavebox using the wavebox controller and a tunze 6100 (with the impeller housing of the old wavebox pump as the 6100 has a larger outlet that doesn't fit the wavebox housing). And it seems to be working out pretty well.

Anyway, I have two pumps, two transformers (one the black box and the other the large hockey puck looking thing) and one silver driver box and don't know whats dead or not. Granted I could just cut the ends off the pump cords (one has a plug thingy and the other has some sort of strange white computer type plug) and try to put some regular plugs on them.

I'm going to stop now or I'll just keep coming up with odd ideas/confuse everyone more

Any help would be appreciated!!
