See if the uncoupler plate is sagging and hitting the center rail. That's has happened to some of my cars.

You can look at the bottom of both trucks for signs of arcing or burn marks.

It's also possible that one or more of the axles are loose in the side frame, allowing things like the coupler thumbtack or the uncoupler plate to hit the center rail.

And buy a cheap meter. the ones that go for ten dollars or so are fine tor train work.

If they are wired wrong , how would are they supposed to be wired? Seems like a stupid question but I just wanted to make sure.

Both center pickup wires go to one terminal on the little PC board.

Both truck frame wires go to the other terminal on the little PC board.

The center pickup wires do NOT touch the side frame wires.

You can remove the little PC board from the frame, flip it over and check/follow the wires.
