2023 HARLEY-DAVIDSON RA1250S

While traveling at highway speeds in heavy traffic, the motorcycle suffered a sudden and catastrophic electrical failure. Without any advance warning, the TFT dashboard display went completely blank, the engine immediately lost all power, and the motorcycle quit running while in the middle of a busy highway.Because the engine stalled abruptly, I experienced a dangerous loss of forward momentum in active traffic lanes. The complete loss of electrical power simultaneously disabled vital safety systems, including the headlamp, taillamp, brake lights, hazard lights, and anti-lock braking system (ABS). This left me riding a dark, dead motorcycle with no way to signal my emergency to surrounding drivers. I was forced to coast across multiple lanes of high-speed traffic without brake lights to reach the shoulder, narrowly avoiding a rear-end collision. A diagnostic inspection later confirmed that the failure was caused by a burned-out alternator stator, which failed to charge the battery and starved the motorcycle's engine control unit (ECU) of power until the bike shut down entirely.
