So all is Zen now with this bikes electrics. I guess what I learned is that is no matter how long your in the moped game, if you get too comfortable, you can fall for the same old gremlins.
Seems like every time I repair annoying electric issues that voice comes booming back in my head, "IT'S THE GROUND, IT'S THE GROUND"
So now I am thinking, with the shaky ground at the tailight, when I cut the clean ground by squeezing the brake levers the ignition coil in search of another path to ground only finds a weak dirty path so all the energy from the coil going to the spark plug gets backed up in the brake light bulbs filament causing it to pulsate and burn twice as bright at the same time killing the spark at the plug?
If wish someone could put this into better words to relay what I am thinking
