2004. The 2004 model is experiencing the same malfunction that the 2005 and 2006 models are experiencing. I researched further and found numerous complaints on the internet of owners with the 2004 model experiencing the same exact problem.

2004 Big dog motorcycle. Motorcycle keeps losing all electrical power when riding on the interstate due to an inherently defective electronic harness controller. This same ehc had been recalled in 2005 and 2006 for the same problem. There was no crash but I hit construction cones and almost crashed trying to get off the highway and out of the way of traffic. *Jb
Dt*: the contact stated the motorcycle seems as if it attempted to start itself after the motorcycle became wet. The vehicle was taken to the dealer who changed the gaskets and greased the connections to stop the water from shorting out the electrical system. The manufacturer has been alerted.
Electrical wiring malfunctioned. As a result, the brake light and turns signals failed. Dealer has kept the motorcycle for six weeks attempting to repair the problem. *Ak
