Not saying this is the same as your problem, but it could be.
A few years ago I had a problem with the stater on my Harley Ultra limited. This bike requires a pretty hefty battery for good cranking speed. At first I thought it was just a worn down battery. I tried using my jump pack and it didn’t have enough power. So then I used my 45 year old jumper cables and a known good car battery, still not enough torque to turn the engine over with the plugs installed. I just about figured I had a bad stater when I felt a very hot spot on one of the jumper cable alligator clips. Corrosion on the clamp was keeping it from providing enough current. So the original problem was a bad battery. My Jump start battery pack didn’t enough current and my jumpers cables couldn’t carry enough current, all leading me into misdiagnose the real problem.
