When using a HiViz delay circuit to trigger my Canon 430ex or 580ex flash, the flash unit is disabled after each discharge until I turn the unit off and on again. What can I do?
Versions of our kits prior to v10 used the 22-kΩ resistors shown in this photo. If this is what you’re using, try replacing the 22-kΩ resistors with 1-kΩ resistors. Or try this method reported by Brad Steel: Connect a 4.7k resistor in between the delay SCR output and the flash wire. We think this has the effect of limiting residual current in the Canon trigger circuit that would otherwise keep the SCR closed.
