Redwing. Do you mean "does the bike spin over then start when you release the starter button"? If so, then yes. It has always done that since I've had it.
You will see a difference when you put the new battery in. That battery is weak. Very, very common sign of battery or the way out. I suspect the battery went dead when you were checking the trailer connection originally and that set the whole thing in motion. Replace the battery and just do one more test. Connect the voltmeter to the new battery and read the voltage with the engine off. Now start the engine and run at a slightly higher idle by adding choke. Is the voltage higher than static voltage was? Is the voltage going up ever so slowly? If the answers are yes you are good to ride.
Worked on the "big rigs" for 45 years now just riding my Wing whenever I can. Gets cold in Wisconsin.
