Inability of starter motor to turn over the engine
I have a brand-new 6 volt battery. I have a recently reconditioned starter
motor. The vehicle is a 1928 Model A roadster. When I engage the starter
motor, it will turn the engine one revolution and then stop. If I re-engage the
starter motor again, it does the same thing--one revolution and stops. With
the plugs out, the starter turns the motor easily. There are no stuck valves.
Why won't the starter motor turn the engine over long enough to start?
Is the battery connected as Positive ground?
