W A C Low Voltage Lighting

Badoish

I'm looking for some help trouble shooting a new installation of low voltage closet lighting. These are 120v to 12v AC transformers, a ball switch in the door jam and a 20w halogen recessed miniature can. There are 5 doors each with a ball switch in the upper jam. I have three WAC lighting transformers supplying the lights. Two of the lights won't come on unless I have the third door open but when I close the third door the other two lights will stay on. They aren't even in the same output loop. If anyone has had the same problem please clue me in. The tranformers run on a very high frequency and I used 12 gauge 30v wire for the output. Any info would be great.
