AN AMERICAN FLYER® REPAIR CLINIC
From Port Lines Hobbies
Lionel electronic e-units used in the
American Flyer diesel engines can be prone to failure…..especially the earlier
diesels. Moreover, the ERIE diesel
contained a seriously flawed e-unit causing it to run very poorly. There is an
ERIE upgrade kit available, but it is not a simple task (see Repair
CAUTION: When making solder
connections to the can-motor terminals, do not apply heat to the terminals any
longer than necessary, as this excess heat can cause disconnection of the wires inside
2. Note that the original e-unit is
attached to a U-shaped metal bracket. Remove the two screws which secure the
bracket to the engine frame. Also
remove the original lockout switch from the frame.
3. Cut all wires that lead to the
original e-unit, and remove the e-unit.
4. You will notice that the Dallee
e-unit comes with a plug having 6 wires, and a second small plug with two wires.
NOTE: Make all of the following
connections before attaching the plug to the reverse unit in order to eliminate
any potential heat damage to components.
BLUE solders to the pickup shoe box
on the sideframe assembly for the truck that has un-insulated metal wheels on
the right side of the engine (when facing forward).
BLACK connects to the pickup shoe box
on the other sideframe assembly. (I’m really not sure why this makes any
difference, but that’s what the Dallee instructions state.)
RED and BROWN connect to the two
terminals on one can motor.
YELLOW and ORANGE WIRES should be
shortened and connected to each other. Be sure to tape the ends so they do not
short against anything else.
You will need two additional pieces
of wire to use as jumpers from the terminals of one can motor to the second can
The headlight wires should be
connected to the same red and brown wire connections. Be sure to insulate any
spliced connections with electrical tape or twist-nuts.
Carefully make the plug connection.
Place the engine on a section of test-track and apply power.
If you are installing a Dallee Lockout Switch, you MAY find it necessary to drill a new hole in the frame to position it without being in the way of the e-unit. Mount the switch, and solder the wires of the remaining two-wire plug to the switch terminals (use the middle and either one of the outer terminals on the switch). Insert this plug into the small socket on the e-unit.
