I bought a polaroid 360 on line. The seller included the flash and flash charger but noted in the description it doesn't operate. I have to do a battery conversion on the camera itself but the question I have is about the flash. When I plug it in sometimes it will power up if I jiggle it and it somehow makes contact. However, usually it doesn't make contact so it can't charge the flash. Do you think it's the plug on the charger? Perhaps a short inside or dirt on the contacts? I want to see if I can actually charge up the flash. I should add it looks from his description that the charger did come on but the problem was with the flash itself..although I'm not sure..especially since the batteries in the camera were dead and corroded (again, not a big deal...I'm converting it to AAA's anyway.)
