Wiring on Dapol ND-030 class 66
« on: October 12, 2017, 10:04:20 pm »
Have bought this off Ebay as a spares and repair. The chassis runs fine. The problem is the wiring from the chassis to the body to run the lights.
There are two wires from the chassi to the socket white and blue (the socket is disconnected).
There are three wires from the matching plug to the PCB on the body, white, green/blue and red. Unfortunately the red and the green/blue wires are detached from the PCB so I don't which goes where..
I am assuming there should be another wire running form the small PCB under the DCC blanking chip but from where and what colour?
Can anyone out there assist?
I have replacement pre-wired plugs and sockets so I can swap out the existing wiring and plugs as they are also showing signs of overheating as the insulation is starting to merge together. :helpneededsign:

I have a few dapol class 66s, and there seem to be 2 different types of wiring/PCB layouts.  Can you post a photo of the PCBs ? 
I've successfully replaced the wiring on these before - it was fiddly, but possible.

@greenlaneman  Firstly this is usually done to prevent melt down occurring... First thing you need to do is look underneath the pcb and see if it has a three legged diode or two single zenners.  Test these and ensure they work before attempting to put nay wires back on, as if one leg is shorting to earth your wiring will fry in milliseconds...  If they test ok post a photo of the underside of the board please and the wiring to the lights and I'll tell you what goes where...

Im also guessing the loco you bought on ebay was a recent from the bucket bin in Chirk for 30.... Dapol throw them in the bucket for a reason..

Heed my warning...

This was Evening Stars PCB when I opened the loco to check lighting fault..

PM me and I will send some photos of the PCB boards as I can not be botherd to waste anymore time trying to upload them to the forum, why we can not use drag and drop is beyond me.
Basically the pcb on the chassis has five solder tags at the top, the two outside ones go to the pickups, the centre one connects to the central wire in the light plug and the other two are the outer ones of the light plug. There are two more marked M+ and M- these connect to the motor.

Near the top of the PCB is a three legged black rectangle, this is a BAT54C (KL3) which usually burns out. If you are not able to replace this a new board is available from DCC Supplies, about 12.

The PCB in the cab roof has three connections the centre wire from the socket connects to the track that runs from end to end, the other two connect to the outer wires from the socket.

If you have the outer wires reversed the lights will work in the wrong sense.

After spending two hours trying I have managed to load these photos. Can the moderators sort out this problem by enabling drag and drop, ever since I joined this forum trying to upload photos has been a pain. I have never been fortunate enough to be taught anything about computing all I know, which is very little, is self taught.

ps Only Me, I tried what you said, yes I could drag to a folder but then there were no instructions on how to transfer them to the post.
