If you own a 2nd generation FA-1 with MU plugs at both ends, you may find the front plug does not function. Fortunately it can be fixed by unsoldering two wires and soldering them in their proper place.

REMOVING THE SHELL

Place the locomotive upside down on a soft engine cradle taking care not to damage the horns.

As the fuel tank is very heavy, remove the six screws outlined in red holding to the frame. Fasten the screws back in the frame so they do not get lost.

Remove the ten screws outlined in yellow holding the shell to the frame.

• Two are at the very front of the frame under the pilot.
• Two are under the back of the front truck.
• Four are under the rear truck.
• Two are at the very rear of the frame.

Lift the frame from the shell from the front to the back. If it sticks, check to see if the ends of any grab irons or railings have been pushed into the shell. Back off the screws in the rear mud flaps. Set the frame right side up beside the shell. Re-tighten the rear mud flaps and fasten the ten screws in the shell.

Unplug the two connectors, that are attached to the rear door, from the back of the rear circuit board.

Remove the two screws holding the plastic diesel engine to the floor. Unplug the speaker from front circuit board and set the shell aside so it does not get damaged. Fasten the two screws back in the floor.

CORRECTING THE WIRING

Soldered between PCB-01 (the Plug and Play circuit board) and PCB-02 (the motor block circuit board) are eight wires. The wires to be moved are the red and black wires to the right of the screw. Unsolder them.

Solder the wires to the open tabs to the left of the screw. The black wire is soldered next to the screw.

Congratulations, now both front and rear MU plugs will function in either track power mode (motor switch on) or battery power mode (motor switch off).
