ok heres whats happening i all of a sudden have an electrical issue with these two switches on my layout. first im using O tubular and 022 switches. the red dots represent where the insulated pins are. also i use a ZW transformer. what happened is it was together and i was running trains no big deal, i could go from the outside loop to the inside loop no big deal. i started permanently wiring my layout so i decided to clean the switches and bench test them, they work fine. i reassemble this area and all of a sudden switch A when the engine goes across has sparks from the wheel and it ****es off the E unit on the engine stopping the train.
whats going on? nothing is different.
