Hello Fan?, with my FXSTBII Night Train from 2009 I have a problem. This starts very badly. I had the battery last winter on the maintenance charger. In the spring almost nothing went, so I installed a new battery. With booster this jumped on, but it lighted from time to time to the yellow engine control light. Today I cleaned the candles. In the first attempt the moped jumped very well, in the second and third try then worse and now the new one seems Battery to be empty again, it also comes the red battery symbol. What can this be! Either a consumer constantly pulls the battery empty or this is not charged by the alternator anymore. What do you suspect and how do I get closer to the cause? Thomas
