Recently installed a rebuilt E unit and followed the wiring diagram in the Greenberg's repair manual (1945-1969, page 173). The collector shoe, headlamp and horn relay are all wired to a single terminal on the unit. I confirmed all wiring.
I'm using an MPC-Fundimensions era transformer, type 4090, the direction and whistle switch is one lever on the transformer, push it to the left, the direction will change, push it to the right, the whistle will sound (although my horn is not working, but that's a post for another day). Here is the issue: no matter which direction I push the lever, the direction of the loco changes. Any thoughts what may be causing this to happen? Is it semantics or is there a difference between horn and a whistle and perhaps this is part of the issue?
