cb450- 42 years old in June

A chilly morning and cool day. I had a fire this evening again. I tinkered with the cb450 today- organizing and figuring out the wiring in more detail. The bike has a grounding harness, separate from the main wiring harness, that seems to have been added after it left the factory- I'm going to use it. I'm now clear where the ground connections are/go and all electrical devices are accounted for.
