Installing the current pickups and the
lighting board
Remove the 2 axle pairs from each boogie, and insert the current
pickups with the factory attached wires. Match the 4 folded ears to
the holes of the boogie.
Insert the 2 axle pairs back to the boogie. On each boogie, the
isolated wheels must be on the same side, and on the two boogies
they are mirrored. Only with this wheel arrangement is possible to
collect both polarities of the DC/DCC signals from the track.
Improper axle arrangement can lead to short circuit on the track
(axles on the same boogie with opposite polarity) or unpowered
lighting board (opposite boogies with un-mirrored axles).
