Plate 121:  Installing a Hornby Point Motor: where the wires go, Part 17
(This plate added OCT 2003)

Operational Testing of Hornby Point Motor, Part Four of Four


Green wire in top socket of R044, red wire in bottom socket of R044

This view shows the fourth of four electrical tests of the R8014 point motor. The lever of the R044 lever switch has been moved to the right, and the R8014 point motor has responded by pushing the sliding arm of the R8015 base plate to the extended position, thereby sliding the switch points so that a train will be directed to the "straight" track.

We therefore draw the inference that when the lever was moved to the right, the bottom wire that was plugged into the lever switch (the red wire) carried current to the red-wired solenoid, which pulled the plunger in a direction toward the tracks, thus extending the sliding arm in the base plate.

Conclusion: when the R044 lever switch is viewed from the side where the brown wire plugs in, and the lever is moved to the right, the wire plugged into the bottom socket of the sloping side will conduct current. In this case, the red wire was plugged into the bottom socket, and the "red" solenoid was accordingly energized.
