I ran a line directly from a fully charged battery directly to the starter positive terminal and another one directly to the ground. Same result as when run the normal way. Starter engages, spins up but just can't seem to turn the flywheel. If I pull the manual starter cord to give it some help it will spin the engine rapidly for several revs, but eventually it will lose speed and stop again.
