[QUOTE="WayneF, post: 441351, member: 12496"] I don't have experience with a bad one, but it is not sounding good then. You can test it this way. Using a metal paper clip or small screwdriver blade, or any small metal thing, then if you short the foot center pin to the metal foot, it will trigger. There is only 5 volts there, no issue about shock or sparks (but don't aim the flash head at your eye, and don't lay it facing down on anything that can scorch). There is one pin toward the front, and two pins at the rear, and the middle pin is the center pin. Put it in low power Manual mode, and then repeatedly shorting the center pin to the foot should trigger it every time. This is normal operation, it is protected from damage, and that is how the shutter triggers it, by shorting that center pin. If it doesn't flash then, something is wrong. If it does flash reliably, the camera ought to be able to do it too. Where did you buy it? Neewer is different than some imports, in that they have a six month warranty from authorized vendors.
