Thanks for the ideas Para, and maybe she should drag out a multimeter for the attys, but I'm thinking they're history because they are not working on any other PV either.
Ooops; my bad

Look at the center (positive connector) in the bottom of the atty.....if the center pin jammed up and shorted it out, it will probably be shoved up or to the side...that's been the case for the ones I've seen.
Once you measure the opening in the end cap I'm pretty sure I can help you fix that
