    While trying to find out why my back brake light isnít working I lifted the tank to check the wiring.

    Someone has taken off an alarm and joined the wires back up by twisting them together and wrapping them in insulating tape.

    Obviously this isnít ideal so whatís the best method to join them bearing in mind thereís not a lot of wriggle room in the loom? I canít use anything too bulky as a lot of the wires are joined at the same spot.

    The best way would be to solder and shrink wrap them.

    Has anyone yet created heatshrink that can be installed after the soldering process?? (for those somewhat forgetful people amongst the population).

    Your "mate" could use self amalgamating tape instead of heat shrink

    Ha.
    No, I had this issue last month where the heat-shrink was a tad shorter than I wanted.

    Bodge way of doing it, and the only way I could find, was to split the heat-shrink length ways with a nice neat straight cut, then overlap the join once over the wires and superglue them together along the whole length, then apply heat as normal.

    You can get crimp connectors with integrated heat shrink from RS components, this would give you the extra couple of cm you're after : https://uk.rs-online.com/web/p/produ...B&gclsrc=aw.ds

    As always, using good quality ratchet crimpers is recommended for strong joint

    <edit> I've got a load at home- PM me your address and I'll send you a couple if you like

    As done by the Japanese factories IME: Twist the wires together and use a suitable diameter of heatshrink to keep them in place. No soldering needed, also it's easy to add a length of wire.

    It can be done reliably, used by BT on old paper insulated copper cables, BUT it is very dependant on technique. Twist needs to be long enough, tight enough, and cut off in a very particular manner to cold weld the ends. Needs enough slack to do, and I really wouldn't recommend it as a reliable method on a motorcycle.

    I rarely use anything other than these on connections that aren't permanent.

    My personal choice is to solder, heat shrink then tape a small length of tie wrap just past the each side of the joint to give it reinforcement as solder joints are brittle.

    I've never found properly soldered joints to be brittle. In my experience, when they fail it's because people haven't ensured the wire is hot enough to melt the solder so the joint is just "stuck".

    Sorry what I mean is they can affected by vibration and fail. Not so much is in a bundle of other wires but if a single, but as said this is just my personal preference
