Have an 02 fatboy fuel injected battery went dead last year and wouldn't crank once charged took it to HD dealer alls it was was the start relay Monday it cranked over battery was low charged it then nothing so I replaced the start relay again and nothing everything comes on just won't crank any suggestions??

 

Try another battery out of a friends bike, also make sure all connections are tight at Both ends

 

Check the voltage on the battery. Check to ensure battery cables are tight. Take it from there. Use a battery tender.

 

Well I took the top off of the old start relay and pushed it in the bike will start runs for about 3 seconds and shuts off

 

Try cleaning the connectors for the relay. It sounds like it might be corroded.

 

Many times in here it ends up being the KILL switch is Off..

sounds to easy but many have done it.
