So I started hurry back home before the battery will be totally dead. Also engine check light came on. In 10 minutes the battery voltage slowly dropped to 11.5 volts, all this time I rode there was no any charging and no voltage response on RPM. But in 10 minutes the charging had come back and I had come home with no issues.
At home I turned engine off and turned it on again. Then I started to wiggle the wires and the fuse box under the sit, the charging was OK. I wiggled the wires and connector under the left side air scoop, there was no any affecting on the charging. Then I twisted the throttle and charging disappeared again and voltage gauge showed 11.6 volts with no response on throttle anymore! I again started to wiggle the wires under the sit with no luck to trigger charging back. Then I twisted the throttle again and charging went back. Then I played again with throttle and wires and was not able to disappear charging.
For me it looks like there is bad connection somewhere or damaged wire. How can I check what exactly happened? Is it possible that it is bad voltage regulator?
Also I noticed the fuse box was hot. Is it normal?
