Is my battery pack for my sb800 working?
I got a battery pack for my nikon SB800. Put the 6 AA's in plus the 4 in the flash. Connected the two cords. My question is, how do I know if it is working/contributing power to the flash? It looks like there is a red light on the pack, but it doesn't come on. Not sure if it is just the 4 batteries in the flash that is powering it.
