Riding along my 2002 Ultra would completely die, come back to life, and die again etc., and sometimes completely die, a complete failure of electrical system - no lights, no horn, no signals, no radio, no engine, and no instruments. Once I got to the side of the road, I turned off the ignition and turned it back on and everything came back on, the bike started, and I could continue the ride. Sometimes it would reoccur in a matter of minutes other times I have ridden for a great length of time over an hour before it would occur. The HD dealer has checked the charging system and all wiring and replaced the main circuit breaker but the problem continues. Help!
