https://www.kymcoforum.com/index.php?topic=33917.msg237955#msg237955My Super 8 150 has two issues that are probably unrelated, but I've failed to figure out how to fix either.
The first issue is my rear left blinker blinks hyper fast, while the front left blinker has stopped blinking. And sometimes, but not lately, a similar thing happens to the right side. This had been an issue for the last two weeks.
The second issue is that now it won't start. It cranks like a champ, fuel is flowing into the carb, but no visible spark from the spark plug. That said, if I hold the plastic connector with the spark plug in my left hand, and squeeze the metal breaks in my right hand while starting the engine, I'll receive a sudden electric shock to my left hand directly through the plastic. I was driving the bike fine the night before, and the next morning it refused to start again.
In my attempt to fix it, I've replaced the 12V regulator, replaced the light controller (assm?) box, replaced the CDI, replaced the spark plug, battery is good and fully charged, replaced fuel lines to transparent lines and can see fuel flowing, replaced vacuum fuel pump, and replaced the filter.
My theory now is maybe a blinker light has a short or the cable harness is bad, causing a grounding issue. But, haven't attempted to address this yet. Everything else electrical on the bike is working great.
Any ideas?
I'm no mechanic. My background is in designing circuit boards so that's gotten me about this far....
edit: Maybe not relevant, but the kill switch seems to have no effect. It cranks and everything electrical turns on regardless of the kill switch position.
