To allow for alternately blinking ditch lights:

Leave one set of  set of ditch lights connected here.

Connect the other set here or here.

There is no need to change bulbs to complete decoder installation.

All the light bulbs supplied with the loco use 1.5v bulbs and are powered from a built in 1.5v regulator on the light board.

Both Ditch lights are hooked together and will operate on and off by using button one.

To provide alternately blinking ditch lights, the bulbs must be separated at the point marked F1_N and F1_P. See enlarged photo of circuit board above.

One bulb then needs to be hooked to the terminals marked F2_N and F2_P or the holes marked 2X and 2Y. The other bulb remains connected to F1_N and F2_P.

 Use the TH141, T2 or T3 decoder as they support Blinking Ditch lights.

Change these CV’s to set up your TCS decoder for alternately blinking Ditch lights.

CV36=4

CV50=42

CV51=43

Use button one to control on/off of Ditch Lights and button two or five to activate blinking.
