I recently acquired a Type V transformer. The cord has been replaced, and each throttle puts out about 22 volts when it's maxed out. I assumed that with 4 throttles, that for each pair of posts, one is the common and the other is the "hot".
But here's the thing. On my MRC two throttle transformer (the one that looks like a ZW), the commons for each track and the accessories are all wired together, just like on a ZW. On the type V, the commons don't appear to be connected, as when I tried to run a train with it, the train ran when I connected the wires to the pair of taps assigned to that throttle, but if I tried moving the common wire to the next common terminal, I got no voltage out. Are all the hots and commons independent on this type of transformer?
I'm assuming that the bottom terminal is the common. Is this incorrect?
