Hey been searching for an aswer to this but haven't been able to find anything. I bought a brand new Leader Bulkhead on clearance last month. The headmaster unit is not working though. It worked for about 2 or 3 tries and then just stopped, meaning, i put it on and push the button but there is no change from Bulkheads regular sayings. Has anybody else had this problem and any ideas for a fix? Thanks.
