Gentle prising revealed "held together with Snaps" noted positions of wiring plugs,

took apart expecting dead fuse/component. Always go for the simple solution......

the battery box was cracked! repaired with cement and strong tape. Reassembled

and tested................perfect.


Take very great care with the main capacitor.Awesome beast ~300volts DC at a high amps .....would make your hair stand on end for a week

Nikon Speedlight SB-600 keeps firing


I believe that there is a safety feature built in that if the voltage in the capacitor gets too large the flash will fire, to prevent damage, could be this that is faulty, if it is a new main circuit board is required.

Ready light does not come on. Unit will not flash from camera or flash button on SB-600. No visible damage to flash tube


Looks like the condenser is not charging. Oscillator section, transformer, transistor has to be checked.
