I donít think youíve done too bad a job with the soldering, and practice does make better. With jobs like this though a small iron with a small tip makes it a lot easier. I mostly use a 15watt Antex with a 1mm tip for this kind of stuff.

You may find, as I have with many Farish non-lights pcbís, that you need to remove them completely to get decent running when a decoder is fitted. With the 03/04/08 the pcb is soldered onto the motor tags, so un-soldering/removing it and fitting the decoder wires direct to the tags is quite straightforward. The difference in running is marked. Chalk&cheese/night&day kind of thing.

Cheers @Izzy it did/does look quite rough.

I'm happy to admit  :dunce: here, but are the pcbs the 2 blocks soldered onto the board in front of the motor??

IF I unsolder and removed them do my grey and orange wires go to those 2 bits instead or stay where they are???

 No, pcb is printed circuit board, on which all the bits are fitted. On the 03/04/08 these can just be removed entirely, they are soldered to the motor tags. So fairly easy....

Oh ok sorry  :dunce:

So if I'm making sense of this,

Red = stays on bronze angle behind gearbox
Black= stays on bronze front peg
Orange= goes to left pad that the pcb was solder to
Grey= goes to right pad that the pcb was soldered too
 :hmmm:

Can't see because of the low quality of the pic and the solder blob covering what I am trying to see but were the black wire connects to the contact that normally touches the motor, did you snip the bit of metal off that holds the contact against the motor or is it still there, if it is snip it off, as it will not work with it in place.

Oh please donít be sorry, itís all a learning curve we have all been at sometime.

And yes, thatís right, what you understand. Youíll get there I am sure.
