Trey; The Rocket is hard to crank. Even a new battery fully charged might miss the energy to start. I had been tightening my battery poles with a Philips screw driver. Not good enough I discovered. A dirty surface might not make a solid connection. A new battery, that might start any other bike, will fail to start the Rocket. It will click but fail to start. Not all Rockets are like that. Some folks report having the same battery for years without a problem. I am not in that category. Mine, at the slightest weakness, clicks and will only start if I jump it with the charger on. Once it starts and runs for a few minutes I'll turn it off and it will restart no problem. I have a weakness in the circuit somewhere. Fix it and it comes back.
There are some electro-experts in the group that might be able to explain this better. My most recent solution was to install a battery monitor that records the resting voltage, charging voltage, response to the stress of the start and available cranking amps. My voltages are good but the cranking amps fall to borderline. Battery is a year old, always on a good cycling charger. Also purchased a lithium battery with very high cranking capacity. Expensive but, I hope it fixes my problem. This is a vice on this bike. Just like the idle and surging throttle issues and solenoid issues and several other issues. When the bike runs, I kiss her. I know she will have problems again but, I forgive her. The folks here help a lot. There is nothing like the Rocket. Only the Valkyrie approaches it. Good luck.
