[TCML] testing mmc capacitors



Talking about MMCs and potential failures brings up an interesting question of "how do you find out which one is dead" (assuming you didn't kill the entire string)..

Obviously, if one of the caps reads shorted with a ohmmeter it's dead. But I suspect that you can have a "fails only with HV" sort of thing.

I wonder if setting up a test rig that puts 120 or 240V across the cap would give useful information - that's still low enough that I'd feel comfortable probing with handheld probes.

Does anyone who's had dead MMC have any insight into the failure manifestation?
