Here I soldered a black wire to the light-side motor lead, brown to the light-side track pickup and yellow to the off-side track/motor lead. | The solder joints from my first attempt were too large and pointed. So I retouched them with a dry iron (shake off the excess solder). | Once satisfied with the solder job, I lined the wires up together, pulled the original tape over them and routed them over the motor. |
With the headlight wires run to the sides I was able to reinstall the shell on the loco with all wires out the cab. | I then put the floor of the tender in place, bent the wires properly to fit and stagger-soldered the light wires to the black and brown engine ones | To make the wires fit without running all over for them, I used pieces of light bulb wire. To get into the tender without crimping the wires I drilled 3 #61 holes. |
As predicted, the diodes fit easily. Note that upper and lower pairs are reversed, and that I soldered all 4 together away from the wires. There was no need to reach that joint since I had no rear bulb. | I insulated the outer joints with black paint and fed the wires into the tender. I then soldered the black and brown wires in place to one pair of diodes each and curled the yellow wire for future use. | Finally, I cut a piece of electrical tape to fit the tender width, lifted the diodes and slid the tape under both the diodes and the solder joints.I lined the tender sides with smaller pieces of tape. |
