Mine is not the starter switch primarily what the switch does is ground the relay. The relay is working fine the solenoid is receiving power but the voltage reaching it is to low to fully engage. The next step I will take this week is to test the voltage on the feed wire to the ignition switch. If it is fine then the switch is the next one under suspicion. I do feel that the fuse box on the Rocket is not the best. They use the mini type fuses. If you check the fuses it isn't unusual to fine one with signs of being overheated.Many rocket owners have noticed the main feed fuse to the fuse box overheats.Some time ago I replaced the main line with a much larger fuse type.Now I notice no overheating of the main fuse.One thing I plan on doing this week regardless is to replace the entire fuse cluster with one that uses the larger type blade fuses.The Rocket is a very good bike buts its electrics still leave a lot to be desired.I will keep you informed on what I fined out.
