Wiring your Mainline Color Position Signal to a power source
Y
our Mainline Color Position Signal operates best at 12-18 volts (AC). Have an adult strip
1⁄4" of insulation from both ends of the four wires attached to the Mainline Color Position
Signal, if they have not already been stripped.
Only an adult should perform this task. Always use care when stripping wires.
Connect the other wires to the #153C Contactor and transformer as shown in Figure 2 below.
Note that a separate wire connects the U terminal on the power supply to the #3 Lockon
terminal.
To connect a wire to the Contactor’s spring clips, press down the upper half of the spring clip
terminal until the lower part projects through the slot. Insert the bare wire end into the loop,
then release the upper part of the clip. Spring tension will hold the wire tight.
