Running PW Lionel without an E-Unit
Posted by RRaddict on Friday, July 29, 2011 2:24 PM

Does anyone know of a place that I can look or get instructions for removing an e-unit from a Lionel PW locomotive and connecting it to run without it. I  know it will only go in one direction and that's ok but I just need to know how to connect the wires to the rectifier. Any help would be great.

Can you tell us what (prewar or postwar) PW locomotive you're dealing with?  Is simply turning off the e-unit not enough for your purpose?  Also, what do you mean by the "rectifier"?  They're not usually found in locomotives made before modern times.  Are you thinking about running on DC?

Assuming that you're talking about a locomotive with a 3-position e-unit, your motor has two main electrical components.  One is the field winding, which does not turn.  One end of this winding is probably connected to the frame of the locomotive.  Leave it there.  The other end of the field winding is connected to the e-unit, perhaps with a green wire.  Call this end of the field winding F.

The other electrical part of the motor is the armature, which is connected to by the two carbon brushes.  Call them B1 and B2.  The brush holders are connected to the e-unit, perhaps with blue and yellow wires, perhaps both with yellow wires.

The pickup is also connected to the e-unit, perhaps with a red wire.  Call the pickup P

Remove all the connections to the e-unit.  Connect F to B1.  Connect B2 to P.  If the locomotive now runs the wrong way, swap the connections to B1 and B2.
