The last of my locos to be converted to Railpro and finish my conversion from DCC is my Rivarossi U25c. This loco has a mother board with a 21 pin plug on it. For ease of installation, I purchased the TSC 21 to 9 pin adapter. Simple enough install - plug and play, so to speak, for the main functions and sound, but the extra two accessory (function) wires coming from the 6 pin plug on the LMS3 are giving me trouble.
Here is a picture of the TCS adapter I am using:
The wires go straight to the 9pin plug and are the standard colors. Everything here works fine. Blue if the universal +, white wire to headlight, yellow to rear light, green wire to function 1 (F1), purple wire to function 2 (F2). As you can see it also has solder pads for F3 through F6, speaker, Ground and Cam (cam, I am assuming for a chuff cam on a steam loco).
This particular loco has front and rear lights, number plate lights and two sets of emergency lights - red and white, front and rear.
The number plate lights are connected to 9pin green wire (F1), the front white emergency light is connected to 9 pin purple (F2), the rear white emergency light to F3, front red to F4 and rear red to F5.
I know the circuits work as I have connected them with jumper wires just to test functionality, but for the life of my I cannot seem to get the purple of green wires from LM-S3 6 pins harness to power up any of the lights when connected to the F3, 4, 5 or 6 pads.
What am I missing?
I tried connecting the yellow wire from the 6 pin harness to the ground pad on the adapter, but still saw no success. Any suggestions?
