Wires in sleeve

[Phil C]

Each of my three alternator wires (1965 B40F) has a soldered joint about halfway between where they exit from the primary chaincase and where they disappear up through the valance near the battery (don't ask why!) Each of those soldered joints is covered with heat shrink. My plan has been to have the three wires covered in a single bit of sleeving, nice and tidy. The sleeving I have fits over the three wires okay, but, where the soldered joints are, the sleeving is snugly tight and the wires/joints are pressed together. That's because before soldering the ends of the wires were twisted round each other before solder was applied, so the joints are a bit nobbly.  The sleeving is bound to be tighter in the joint area. I'm wondering about where the nobbly bits are pressed together in the sleeving. Do you reckon a short could happen? Do I need to have them just loosely together? Do I need to use bigger diameter sleeving? All advice much appreciated as always.  Phil

I think you are right to be concerned about these joints being squeezed together and at some time shorting together. Larger diameter sleeving might well do the trick, or you could remake the soldered joints so that the joints don't line up with each other and are not so knobbly, then use the narrower sleeving. With the larger diameter sleeving, you might have enough room so that any particularly pointy soldered joint can get another layer of heat shrink.
