You might look at the wiring circuit diagram and see if the headlight power is run through the ignition barrel (like the early Rockets). The 55 watt pull managed to overheat the solder connections.
Calculus and schematics go together very well, I have found.wonder why I didn't learn how to read that instead of calculus in high school, heh.
Probably for the same reason most people don't learn what they believe they don't need to know. I had to learn both math and electric schematics for my job after college. If you want to know about a circuit on a scheme (or diagram) just ask. Motorcycles are not nearly as complex as the Engineered Safeguards Actuation Systems of a nuclear power plant.I think electrical issues are the quickest to try my patience, as I simply lack the knowledge. I look at that schematic above and wonder why I didn't learn how to read that instead of calculus in high school, heh.
