Hey guys, I have a 1984 KZ550Ltd that I just put back together. It starts and runs now, first time in 25 years. There are two wires that come out of the harness on the left side of the bike by the fuse box.. They are both yellow with a black stripe. I have no idea where these are connected. If anyone has a wiring diagram it would be much appreciated. Working on this bike has been a study in archaeology.

If your bike has an accessory fuse box, at least one of the black/yellow wires is probably an accessory ground wire.

Here's a page with wiring diagrams, but there isn't one for the 84 KZ550.

Unfortunately, my factory manuals don't cover the shaft drive models, but the third party manual in my sig does. There should be a diagram in there. You may have to use the diagram labeled 82-83 F1. You should try to get a factory manual if you don't already.

Yes, I know. Because the bike hadn't been started in so long I wasn't in the mood to invest heavily in it until I was reasonably sure it would run. Finding an F2 genuine service manual is my next priority now that the bike is running.
