My lamp wasn’t working and by putting pressure on where the cable came out of the lamp casing it was clear that there was a loose or broken wire in there somewhere.

Your directions gave me the confidence to open the thing up and have a go at fixing it.

Sorted! There was a broken wire and after cutting a bit off both the red and the black wire and soldering the connections back on we are all systems go.

I should point out that I had to do the soldering twice as there is not much room for anything but the cleanest (or in my case second-time-luckyest) soldering so for others who plan on using these directions do take a good look at the angles of approach for the two wires as showen in the photos above.

Cheers!
