Anyone have a guide and/or pictures on how the reverse unit is put together along with how it works on an American Flyer Wide Gauge 4675 steam engine? I would like to know better how it is supposed to work. Also, do these engines have the firebox glow or was that only on the more expensive models?

Thanks in advance!

If it is similar to the 4692 engine's set up I might have a diagram. Do you have the motor out of the engine? If so post a pic of the reversing switch. Ives1122 is right, adding the firebox light is pretty easy. I added one to a 4670 recently.

If it is like the 4692 Loco I have this should help you. Ignore the line running down the middle, it is from my scanner(same with the close up of the cam). When the R/C lever is pulled up it allows the R\C function. The solenoid is powered and pulls the hook up so the cam can turn freely and the engine runs in whichever direction the FWD\REV lever is pointing(in = FWD out = REV). When power is turned off the plunger drops and the hook is released allowing it to catch the cam and pull the FWD\REV lever to the opposite position. When  power is reapplied it will run in the new direction. If you don't want the R\C to function then pull down on the R\C lever which pushes the hook up and holds it out of the way. Select which direction you want to run and apply power. As far as the wires Brush 1 , Brush 2, and the pick up wire are all Fahnestock clips on the diagram and the other three wires are solder points.

This does help quite a bit. It looks like something is jamming and/or damaged with the solenoid and the cam reverse unit. I can it to go forward and then reverse once but then it shorts out like the rotating cam is jammed and the arm with the hook just floats around so I am not sure. It looks like full motor surgery might be needed.

Are you sure the plunger in the solenoid is going up all of the way? If it isn't it can cause the hook to catch on the cam. Clean the solenoid and plunger with electrical contact cleaner and push the plunger up and down to make sure it is clean and seating completely.

Were you able to find the cause and fix the issue?
