The replay circuits weren't working on my Carnival Queen and I was having a hell of a time figuring out what was going on. First of all, nothing was working. That turned out to be the normal index adjustment, which solved some of it. In-line scores pulled in the search index but the red and green replay counters weren't stepping, although the meter was adding credits - without stopping! (Man, this was probably an operator's worst nightmare). That issue was caused by a funky wiper which is (pretty much) fixed, although I'm not so sure it won't happen again. Sections still weren't scoring. Usually that's the change-over switches, so I adjusted them and it didn't matter. Anyway, after a bunch of frustration I found the problem to be the sequence unit reset plunger. I have attempted a few times to clean and adjust the switch but it's pretty delicate. So I decided to just close it permanently to see what would happen. The sections now score perfectly as well. So the first question is, what is the purpose behind this switch at all, and can I just leave it closed? Second question - I am worried the "I" wiper (outside row) won't continue to work for all colors because someone mangled it pretty good in the past and I had to fool around with the bend and also sort of make some sideways adjustment as well to get it to work in all colors. Any ideas to make this reliable going forward? TIA.
