More iffy triumph connections

Hi everyone.

A wiring issue, trace and fix that might help someone.

While cleaning and tinkering( I ride all year so lots of that needed) I noticed the clock lights weren't working. Mmmmm. Tried my default diagnostic technique- wiggling the wires No luck. Not surprising really !!. OK. check the fuse. AHA I thinks. New fuse fitted and we have lights, well, nearly. One is not working. So, a little while later after removing fly screen, headlight and clock cups I can get at the offending bulb. Its "blown". New bulb fitted and, oh, still not working. Now its time for the trusty Multi-Meter. I unplugged the connector in the head light bucket from the loom and checked for continuity on the wire. No luck. Broken wire or iffy connector I decide.
I start cutting carefully the loom, wiggle a few wires, and out comes this.

More cutting and the spaghetti nightmare appears.

I find the offending connection, cut the shrink wrap off and

There's the problem. Rather corroded and a bit green.
I stripped the wires, practiced soldering as I've not done it for awhile, happy with the results so away I go. Picture of the finished solder joint ? Not a chance !! LOL. It didn't go very well and I was a bit disappointed. Very lumpy, plastic a bit over heated, but ok. Just.

Everything re-wrapped and put back together and good to go.

Hope it helps.

Jon

Since you have that part of the loom open, I HIGHLY recommend you peel back a little further and solder the green/red wires. There are so many weak points in our loom, but to eliminate all of them, requires a complete tear out. If you ever wire in a RFID, you can tackle that at the time.
But for now, the green/red should be tackled.
