Lately I put my wiring harness into my wash tub and cleaned it with water and some dish soap. After it dried I re-wrapped any areas that were marginal or torn. I did have some plugs that were sun scorched and cracked, so I replaced a few that looked like this:
I also noticed that my turn signals are not all the same. One is shorter than the others, so I assume it is from some other Yamaha of the same era:
In the end I will probably not end up using these and replace them with something with a lower profile. Finally, I set everything up on my bench and ran an integrated function test of most of the harness. I couldn't test the charging system, ignition or the starter motor, but at least I could wring everything else out without crawling around the bike:
I had a lot of corrosion in the connectors to chase and clean, and the horn and start button took extra effort to get them back into operation, but in the end everything works except for one burned out warning bulb. This also tested my new fuse box, headlight and keys. I tried the auto cancelling by spinning up the speedometer with my drill and that works as advertised. I don't think I will get to use that feature if I swap out the turn signals, but it was fun to see it work.
Next up will be moving the bike into my shed and get to engine removal, frame cleanup and suspension/wheels. That, however, will have to wait for two other big projects that are in the queue ahead of this one. So it will be on to parts procurement and little odds and ends if I can fit them in.
