I replaced the starter in the M1008 as I thought the 24V one went out on me. It was spinning and sounding like it was grinding, but not turn the motor but just a little bit. Inspected the fly wheel and it looks good, turn the motor by the harmonic balancer with a wrench. Today rewired for 12V, hooked up new starter, exact same problem. The bracket in the front that holds it to the bolck is fastened and the gears are meshing with the fly wheel, but it looks like the starter just doesn't have enough power to turn it. The Battery has 13.8 Volts!!! WTF is going on?
