I'm trying to diagnose a problem I'm having with my 150cc GY6. When trying to crank the engine, it feels like the battery is dead. After spending the day on the charger, the battery still sounded weak. I tried a different battery that I know is good and it did the same thing. It's to the point where the engine won't even turn over. You just hear the brushes buzzing inside the starter.
What I'm wondering is, could this be a symptom of a failing starter? I removed the starter and jumpered power across the terminals and it did turn, but I couldn't gauge how much torque it had behind it. I checked the wiring in the scooter and everything was fine. Before removing the starter, I jumpered 12 V straight to the starter and had the same symptom of it sounding weak. The battery reads 12.8 V with no load and 12.0 V with the starter buzzing and not turning. Does this sound right? Can a failing starter have the same symptoms (weak cranking) as a dead battery?
