With the LCRU board firmly in place, wiring of the motor(s) is a simple task. Read the

instructions carefully and proceed. Refer to the appropriate wiring diagram for clarification.

Engines Equipped With Two Position E-Units

Some of the older, more common Lionel engines, particularly those designated as O-27 types, come

equipped with a two position E-unit instead of the more complex three position type. These

engines use a double-wound field coil in place of the complicated three position E-unit

mechanism to reverse motor direction. Wiring the LCRU to this type of motor is done as follows:

1. Solder the Yellow LCRU lead to one of the motor brush terminals.

2. Solder the Blue lead to the remaining motor brush terminal.
