Old wires !!!
matthewmosse:
I think its electolitic corrosion and fed by current flow or some kind of flux residue if it was soldered. Either way its almost always the re or white /red tracer wires that suffer. So much do that it's the first place I look on my 500/4s. Also had troubles on newer Hondas in the same areas. Ignition switch, red wire or the connections by the regulator rectifier. Only time it really provides a significant difficulty is the wires into the rectifier or reg rec on more modern bikes. I deem it sensible to carry a stock of spare electrical connectors in the workshops inventory, then its just a 10 minute job to fix, rather than wait for parts to arrive, or try soldering old wire to old reclaimed connectors. That and a supply of heat shrink tube. Very handy. Oh, and if I buy a bike, job 1, but out any of those blue or red pre insulated terminals bodgers love to use. They seem to attract corrosion.
mike the bike:
It's electrolytic corrosion, with the big red wire being made of different flavour copper than the others. As they're crimped, flux isn't to blame.

All connectors are not (edit!) the same. I have seen various quality red bullet crimp connectors, the ones I have used (not bodged, thankyou!) are better than some but I'm damned if I can remember where I got them. Perhaps RS? The ones you get in blister packs from Halfrauds are questionable, as the insulator seems to deform completely when you crimp and then not return to it's original shape.
Bryanj:
The ones i use look cheap and nast but the insulation is heat shrink to make a better seal.
If you get technical the corrosion depends on flow of current.
Nurse Julie:
Worry not, i will replace it with the same quality connectors we use on all our bikes. Never short of replacements or spares for anything here at the House of Honda 😀😀😀
I am going to replace the grey insulating tape that Honda put over the 'junctions' in the loom with heat shrink though, before fitting the new loom cover. May as well whilst I'm there., it was falling off anyway.
