THE ELECTRICAL SYSTEM HAD INTERMITTENT PROBLEMS SINCE THE BIKE WAS NEW. HEADLIGHT WOULD FLICKER ON & OFF, REAR TAIL LIGHTS FLASHED ON & OFF. NOTHING WAS FOUND WHEN BIKE WAS TAKEN TO LOCAL DEALER FOR ROUTINE MAINTENANCE. EHC MODULE COMPLETELY FAILED NOW AND BIKE WILL NOT RUN. TOLD THE REPLACEMENT PART IS NOT YET AVAILABLE AND WHEN IT IS, IT WILL COST WELL OVER $1000.00 TO REPAIR AND BIG DOG REFUSES TO COVER IT AND SAID "SORRY, BIKE IS OUT OF WARRANTY". I HAVE NEVER BEEN CONTACTED ABOUT A RECALL. *TR

RQ10002 · Motorcycle Stalling

Opened Jan 27, 2010 · Closed May 10, 2010

Status: closed (inferred from source dates) · Electrical System:wiring

This RQ was opened based on seemingly related owner complaints involving motorcycles outside the scope of 06V-301.During the course of subsequent discussions with the company, we learned that the earlier model year Big Dogs had a problem with the electronic harness control module connector that they'd previously addressed with a TSB.Since the TSB addressed a safety-related issue (stalling), Big Dog agreed to recall the motorcycles subject to the TSB (10V-180).With that decision, ODI agreed to waive requiring a response to its information request and is now closing this RQ.
