Teds new project a CB500 K1 mostly version 0.5 circa 1972.
McCabe-Thiele (Ted):
My cylinder head is having a very light skim to remove a couple of marks that I was not happy with as they were where the four circular metal seals on the head gasket fit around the cylinder bore. Can't collect it from the Engineers until I test negative for Covid (hopefully Friday).
In the meantime as I am feeling a lot brighter I've started to sort out various electrical connections as it is a bit of a mess in several places with the ravages of age making many of the PVC type sleeves hard plus a bit of a mix of connectors from previous work. You can see why I was thinking of replacing the loom but for now making do with some new connector blocks & some tape work fitting new connections where needed.

Not 100% sure but I know the 550 loom routing is different than that Ted. It goes under the lower yoke and is held by a clamp which bolts onto the yoke. Whilst there is no 500 routing diagram to my knowledge I think the 550 routes better. There is also another loom hanger which goes behind the tank mount rubber.

I have a spare loom guide for a 400 that fits behind the left front tank rubber so plan to use that if it helps, as regards the route at the front column area I have atm routed mine like this photo below I think its Julie's 500. No wires connected up as yet as I'm taking my time to get the various wires in the Headlamp bowl in the best position.
My cunning plan (if it even works) is to work with the battery earth connected normally, the starter motor cable disconnected for now. I plan to use an inline lamp between the positive battery post and the live end of loom as a sort of safety fuse (suitably insulated joint).
The lamp I use is an old lamp unit that used to be part of an old car tool kit from the 1950's that you clipped to the battery before the days of illuminated engine bays. I can put a variety of bulbs in the lamp fitting, atm I have a 12 V 5W bulb in the lamp. As I connect various wires if I happen to accidentally contact a live wire to earth then it will illuminate the bulb/or blow it instead of overheating the main wiring loom. I will use my AVO meter & additional Hella test lamp where connections are uncertain.
If its anything like my 400 was most wires are a straight forward colour match so the more that are plugged in the loom the fewer unknown wires that remain. Some colours such as light blue/light grey/ light green are not easy to decide what they are. I'm not colour blind as such but faded colours can be tricky to identify as your eye sight ages.
