i bought a headlight designed for these motors from boygofast on ebay
i had a blond moment and decided to see how well it worked, and hooked it up to a battery charger set on 2 amps
from my diagnosis, the little black cylinder, a resistor i believe, is burnt out.
its connected from the circuit board by a wire and back to the circuit board
could i by pass the resistor by going right around it with another wire
