Thanks for the information, I checked the cables, it's all in good shape, the solenoid activates (clicks once) when the starter button is pressed and clicks off when button is released. The battery read 12.7 V, but I put a charger on and tried it, same high pitch whine from the starter. I think the sprag clutch might be shot as it sounds like the starter does spin. Waiting on the manual now, and will disassemble when it arrives.
