I've been sifting through the accumulated details that are cited in these posts in order to try to understand the arcane circulatory system (if in fact a 'system'? Maybe 'battle' is a better descriptor.) that sparks and rumbles in the wires of these bikes. Akin to certain subjects in school where I was terrified of being called on to mainline my thorough ignorance into the ears of my classmates. Never mind the teacher. I do know that electricity hurts when your cross two poles. I learned that at age seven when I joined the two sides of an outlet in our ancient house. I'll bet the scorch mark is still there. Beyond that, I give my deficiencies a wide berth as I'm sure no good will come from it.
But I've gleaned a lot from the anecdotes everyone here has shared about their experiences with similar problems and I'm grateful for the time devoted; advice offered. I have a couple of patient, electrically inclined friends who've offered to be chaperones in order to ward off the mushroom cloud I know I can generate in the dark recesses of a Moto Guzzi's electrical labyrinth. And I think I can rectify, or a least examine, a lot of the innate problems that have been described in bits and pieces with all your help.
And after all this fatuous hubris-building, I think I should get me a Tesla, a few tweaks and I know it will be a screaming fast monster. What is the secret code? Plus and minus are cantankerous bedfellows.
Off I go.
Thanks again, all,
Marcus
