Do you just enjoy talking down to people? It seems you tend to do it often.
I'd like to hear your conversation with a two year old about the intricacies of the human Psyche, nuclear physics, or electrical RF theory, in a sincere attempt to have the 2 year old understand and absorb the information in a useful way.
You can catch more flies with honey than you can vinegar.
I don't want to catch flies, I want to train and educate them to do the right thing. But, like with many in this forum, there is a huge language barrier, which may or may not be related to basic intelligence, or ignorance. The former can't be trained, the later can, provided a will to do so.
My 76F is still using the original wiring harness. And it operates the same way as Smooth's. Tail and headlight burn.But the signals,brakes,starter button and ignition are disabled
Then your bikes are broken. Why haven't you fixed them? The wiring diagram shows a battery connection to only the brown wire circuit in the II position, and the brown wire only routes to the tail lamp. Why or how, does your headlight get power when the switch is in the park position?
Back to topic:
I can tell you that the CB550 battery will NOT power the tail light for 9 hrs while at work. AND, if the battery is more than 2 years old, the bike is unlikely to kick start, either. Jump starting and keeping the revs above 2k with the headlight off will get you home (recommend idle knob tweak). Been there, done that. With the shutdown routine modified to check the tail light before walking away, being stranded only happened just that one time.
