Did some preliminary testing. In the attached image, the circled diodes test shorted (same readings both ways) and the one circled resistor is open. I haven't looked up how to test caps and transistors with my meter yet.

I'd assume a totally shorted rectifier is a pretty bad thing, hopefully the whole unit isn't toast.
