And to make it worse, I decided to put sound into it myself :( Not a great idea, I'm afraid)
Anyway here is a pictorial started a month back, and still not finished.
I can only guess it makes the thing easier to glue / solder together ??
To cap it off the 8 pin plug is upside down and incorrectly marked (Dot always indicates pin 1 the orange wire!) It appears to have solid bar under the coal load (weight?? why??). The box at front of tender is , or appears to be an empty space.
I wanted to fit a Wow sound with stay alive, but could not find enough room to do so, so have settled for this ESU Loksound V4 installation.
Now this creates a further problem. That is that the tail lights are LEDs in metal containers attached to the circuit board under the 8 pin plug. that has to nestle down in the space right beside the speaker. That means the existing light rods (fibre optics) cannot reach the light boxes. I will have to glue led's directly to the lamps on the rear of tender. I can barely get my fingers in there, so job is progressing slowly! Just noticed a post which shows Eugene has mounted a wow into an A2. Have to ask him a favor :)
You can just see the holes in the rear wall of the tender where the fibre optics poke into the lamp assemblies.
Just noticed I had not shown you my new N Class :)
