I'm rebuilding a '72 K5 CB450. After putting everything back together all of the electric worked fine and bike started, then, suddenly...bike died and starter button did nothing. The horn also was totally dead. Headlight, turn signals, brake lights, etc. all work fine. Blinking indicator light and backlight for the speedo/tach also work fine, but the neutral light does not.
Came back to the bike the next day and, magically, everything worked fine. Bike started and ran. Skip to last night and same thing happened, bike started then, magically, died and horn/starter switch/neutral light all gone, everything else works fine.
Some research shows these are all on the same circuit and if something goes out it would kill all of them...but where do I start in diagnosing and solving this? I have no electrical knowledge so, while I have a feeling it's either the ground or a bad neutral switch...I don't really know how to prove that or what to do about it. I have the schematic and traced most of the connections and, visually, they all look fine.
I'm 99.9% done with a year long build, and this is the final piece (hopefully), so any help would be SO appreciated.
