Hey -
I have 24 switches and power them only thru the fixed voltage posts of one 12B transformer. I use another 12B to basically power 2 loops. I saw an online video about AM switch repair and this person said it's not a good idea to do what I'm doing - that the fixed side of one transformer (I guess) is connected electrically (thru the track?) to the other transformer. I did experience strange behavior and blew up a loco. That could have been another issue - so I saw a video on phasing and that makes sense to be - connect the bases together - but the video was for Lionel O gauge. I believe on a single AM 12B the bases of the 2 track posts and the accessories base post all ohm out to zero - they are connected. In electrical engineering it's good to have everything tied to the same ground, but how would I do this with the 2 transformers? It is also possible to set up current loops - not good. My thought is to connect the accessory base posts together - one is used for the switches, the other unused. Anybody understand this topic who can advise me? Thanks!
