I purchased this electronic E-Unit from a fellow forum member some time ago and am finally getting around to installing it in my GG1. At present the GG1 is wired for one direction only. I want to be sure of the correct wiring when I install the E-Unit in the locomotive. I've taken some pictures of what I have at the moment. One thing puzzles me however. There is a nylon stud sticking up from the floor near one end. Also, there seems to be some sort of glue residue on the floor close to the motor. The new E-Unit matches the glue residue and the nylon stud when I placed it in the loco. However, as you may be able to see, the armature almost touches the E-Unit, and that's with the motor truck perfectly straight. If the truck swivels, it will contact the E-Unit.
The seller sent me wiring instructions, but I would rather have a wiring diagram.
