I have just dug out my old Vivitar 2500 Flash to try with my Canon
Powershot
SX10IS.

It was working and I was getting used to it and then it failed. Tried
fresh
batteries and it is erratic. I hear it whining as it charges but the ready
light isn't coming on. If I press the manual button I can see a faint
flicker in the flash tube and the green light flickers.

Has anyone got any ideas about how these fail?

TBH I was initially surprised you hadn't blown the crap out of the
Canon, as I thought the 2500 was old enough to have it's full flash
voltage across the trigger terminals; but Google suggests it's around
13-14V for the 2500 so presumably that's within the Canon's limits.


I looked through the manual but couldn't find any limits. I will steer clear
though. I had it in mind for a once a year large group photo. I'll forget to
take my camera and let someone else do it!
