Well I finally found time get around to working on this, although I decided to do a quick job with a bit of solder before crimping as it's easier to remove solder if it didn't work!
Before this, though, I'd had to remove two of the "pins" in the connector because another of the wires had come loose and the pins were covered in verdigris
I tried using WD-40 Contact Cleaner on them, but it didn't really shift it, so eventually I ended up soaking them in a saucer of vinegar and then giving them a go-over with a wire brush attachment on a Dremel which cleaned them up nicely.
Unfortunately the pins have the wires crimped to them with the style of crimp that's a sort of "m" shape, with two sections that fold over (and which are a bugger to open up again), so I just soldered a new piece of wire to each of them.
I then had a bugger of a job trying to solder the new wire to the old one, but managed a bit of a bodge with a big lump of solder...!
Except, after this, although things had improved a little and the warning lights were working ok, the display was still missing a lot of segments or they flickered.
So I've taken the instrument cluster off again and I'm going to have to try to open it up with the cutter on the Dremel.
Unfortunately that thread I've found (see link above) with pictures doesn't say where the person who did it actually cut or how the two parts sit together, so I'm going to have to find a part that's away from the internal circuit board and cut a slot that will hopefully give me a clue.
Then I'll very carefully try to take it apart, at least they give good advice on how to clean it up and, hopefully it will work again without my needing to replace the whole unit as second hand ones come in around the £130 mark (and read the wrong mileage!)
Just for extra laughs, the MOT is due on Monday, although I don't need to ride the bike regularly at the moment and I store it off the road, so there's no massive rush to sort it...
