O Line Reproduction Switches acting funny, Please help

60 years of toy trains and I still have issues with turnouts!  For my retirement I am putting together a small layout roughly 5 x 9 using K-Line Supersnap and Shadowrail with 2 independent loops. I have 5 O- Line Reproduction O-31 switches (all new-bought them 2 years ago)--3 lefts, 2 rights.  The 2 LH on my inside loop work perfectly. The 2 RH and 1 LH on the outside loop either don't work or chatter and won't switch. I am using track power. No matter how I arrange the 3 wires on each, nothing seems to work. I've checked the entire loop for shorts and it is OK. All insulating plastic pins seem to be in the right place. Transformer is Z-1000. Please give me ideas! Thanks.

Make sure the insulating pins are in the right positions. They should be in the inner, short rails. Chattering is usually a signal that the switch is getting told to switch both ways at once. Disconnect the controllers and try pushing a car through them both ways. If that works the problem is how the controllers are connected.

Thanks everyone for your comments. My son came over today and we solved the problem. It seems there was a factory error on the controllers-- LH controllers must have been packaged with 2 of the RH turnouts and a RH controller was packaged with one of the LH turnouts. I found this out by opening  5 of the "extra" switches I had bought new several years ago., and sure enough 2 of them had the wrong controllers. All work fine now, so I can get back to laying foam roadbed before doing final wiring.
