[Jukebox-list] rowe jao-200 banstand help please

[Rick Force]

Hi all,
I have been trying to get this juke (1100 record changer) to select properly 
but can't, even after following the complete selection service manual. 
Here's what's going on:
Coins register properly (but credits don't cancel out apon selection), 
buttons latch and then start the search unit ans release as they should. 
Then, if side one (a left side) is selected, it punches the correct pins. 
But if side 2 (right side) is selected, it is way off. Then, the magazine 
will rotate but hop over the selected pins (no matter which side is 
selected) and stop after a complete rotation (like it should). Now, 
sometimes (while the magazine is at rest), if I push one of the stop sw 
feelers, it will pick up that selection (got it to do that several times), 
but not while the magazine is rotating looking for the pins. Several years 
ago, I replaced all of the cam sws and the 2 stopping sws, so what's left? 
While I had the search unit apart this time, I cleaned the very back slip 
rings and feelers and cleaned both sides of the search unit board and wiper 
feelers, no affect. Now, maybe those stop sws are bad again? I do hear a 
slight buzzing sound when I activate one of the stopping sws (when it won't 
pick up), but haven't found out where its coming from and how its related to 
that stop circuit. Thank you for any help on this, Rick.
