MOTORCYCLE ELECTRONIC SPEEDOMETER AND TACHOMETER LOST POWER (NEEDLES TO ZERO). FOUND THAT BRAKE LIGHTS, TURN SIGNALS, AND EMERGENCY FLASHER LIGHTS WERE ALSO A NONFUNCTIONAL, LEAVING ME UNABLE TO RENDER ANY OF THE STANDARD WARNINGS OF STOPS, TURNS OR TROUBLE.*AK HD MECHANICS BELIEVE THAT THE FAILURE WAS THE SPEEDOMETER AND SAY THAT THE FAILURE IMPACTS THE LIGHTS AS THE TURN SIGNALS' AUTO SHUTOFF IS INTEGRATED WITH THE SPEEDOMETER. I THINK THAT THIS DESIGN IS FAULTY DO TO THE LACK OF REDUNDENCY OR SEPARATENESS IN THE CIRCUIT WHICH ALLOWS A SINGLE FAILURE TO WIPE OUT ALL SAFETY AND LEGALLY REQUIRED LIGHTS HD IS REPLACING SPEEDOMETER IN HOPES OF REMEDIATING ELECTRICAL FAILURES.
2006 ULTRA CLASSIC HAS SMOKED SINCE DAY I BOUGHT IT! HAD ONLY 2 MILES ON IT WHEN I WAS GIVEN THE PDI BY SALESMAN. BIKE IS STILL SMOKING ON STARTUP WHEN COLD. SO FAR HARLEY'S ONLY ANSWER IS TO WRENCH MY ENGINE, WHICH IN ESSENCE MEANS I HAVE PURCHASED A USED BIKE FOR A NEW PRICE! *JB
