Let us know what happens with this...my experience with motorcycle batteries is that once there is an issue with them, they never fully recover like a car battery can...

 

Hello you know when you hit the starter you put a big load on the battery and if you have a weak battery it will fall on it;s face soon as the starter is used" the ECU or I should say the computer in the Dyna has to have a full 12 volts at all times to work right, try this with your bike running check the batter and see how much voltage is being pumped into the battery it should be near 14 volts or a little more then shut the Bike off now check the voltage again it should be 12.69 or a tad less if it's way less then your battery is **** up Now hit the starter and see if it starts? ok shut the engine down and check the voltage again if it's 12 volts or less you need a new battery, I just went through this my self"
