Batteries corroded in Nikon Speedlight 600. I cleaned out the battery compartment with alcohol. Now, light works except the flash fires on it's own every few seconds. Any thoughts on how to correct the problem.
I would use white vinegar and not alcohol. Might have to open up the unit, maybe just the bottom as that has the circuit boards closest to the battery compartment. Best to make sure you know how to discharge the capacitor before opening any flash unit, these can hold a high voltage charge for a long time even with no batteries in the flash.
I hope you didn't just pour some alcohol into the battery compartment, because the alcohol would have seeped into the adjacent housing. I don't know what alcohol does to electronics, but water will pretty much ruin them.
I think you've got either a fixable SB-600 or a piece of junk, so why not see if you can get the case apart and at least allow everything to dry completely.
