"My flash cable and sockets are wet - what am I doing wrong?"
Make sure that your plug connections are dry when you unplug them. Water can otherwise reach the socket or the plug. Clean your plugs and sockets with alcohol and dry them afterwards. The best thing is to blow-dry them with compressed air. Treat them now and again with a drop of contact oil - corrosion is thus reduced, the contact security and lifetime are enhanced substantially. Only dry contacts guarantee a flawless TTL control.
