The battery contact spring has broken off. I need to disassemble the flash in order to get back in there and either replace it or solder it back together. I can't housing to come apart though. I've taken the screws out of the bottom mounting plate which opens that side but I can't see where the top locks together. I'm sure it's those stupid plastic tabs that lock but I see where they are to push them open with a screwdriver. Anyone know of an easier way to open the case up?
