i have a 2005 fatboy with the 95cu.in. motor. sometimes when i press the start button it just clicks like its trying to engage starter but the battery is dead. but the battery is fully charged and if i keep pressing the start button eventually it will roll it over and start. it happens when bike is cold and when its warm. therev is no pattern to it. i have heard maybe the battery isnt big enough or have enough cold cranking amps but i dont know if thats it. any other ideas would be helpful. thanks

 

check your cables
check your ground cable on the frame

 

light click = starter relay
heavy click = starter solenoid.
replace the relay..if light clck'
clean the contacts in the solenoid including plunger ring if heavy click....

 

At times when I go to start the bike I get a whine then starter engages. Starter going or something else?
