That must be a realllllllllllllly 'special' battery & starter that cranks 'just fine' with 10 volts......

New aftermarket starter. That says it all. Get the starter rebuilt by a knowledgeable, reputable rebuilder.

Most, if not all "mini or compact" new starters use rare earth permanent magnets in lieu of wound field coils, to reduce physical size and therefore deliver more amps to the armature for greater starting torque. ......just thought you might like to know the reason....
