1) Get a volt meter, or VOM meter (Volts-Ohms-Milliamps). 2) Put fresh batteries in your flash and turn it on. 3) Put the black lead of the volt meter on the center contact on the bottom of the flash. 4) Touch the red lead to the other contacts on the flash, one at a time. At least one of them will show a voltage difference. It could range from a couple of volts to well over 200 volts. This voltage is present on the contacts of the flash when the flash is on and energized. IIRC, the camera dead-shorts these contacts to trigger the flash. I'm not sure how energy is used on the other contacts, like TTL, digital, etc. TTYL, DougF KG4LMZ
