Quoted from desertT1:On Whirlwind I have been getting locked balls kicked out automatically. I asked on here and the first suggestion was to replace the 3 lock switches. I did that and played a few games without issue. On the last test game I was going to play sure enough the balls kick out. So about the same regularity prior to the new switches. It hasn't mattered if there are one or two balls locked.
I set up both 1 and 2 balls locked and triggered each switch on the rows and column that are shared with the 3 lock switches. I did this multiple times. None of them triggered it to kick out the balls. One thing to note is that when it kicks out the balls it just kicks them out. If there is one locked and I drop another into the lock area (as if the next highest switch is triggered) it will say "ball 2 locked" and then kicks out the next ball. So at this point I don't think it's a lock switch activating and causing it to kick out.
I had this happening with my Big Guns and it ended up being intermittent connections in the cabinet/backbox connector for the switch harness. It would seemingly randomly come and go and generally switch test looked totally fine.
Quoted from Daditude:I am looking to buy Big Guns in the near future.
Any advice or recommendations?
I haven't seen any listings for it in awhile.
Check the wireforms for broken welds. Check the paths to the two side lock shots for wear, those are the only spots I've had wear through on mine. Also make sure it's got the little ball for the bagetelle, AFAIK there's no replacement available if it's missing.
