Re: Starter won't crank

If it were my starter, rather than try on 12v I would take the 6v battery someplace and have it checked, add proper electrolyte if needed, have it charged with a decent charger then checked again with a carbon pile load test to verify the condition.

Starters can run on 12v briefly and many do but those starters are all mounted in the car with a load to turn. I would be very concerned that trying on the bench without a load to slow it would result in a possible over rev and damage to the armature. There are pictures of armatures that have flown apart on motors even with a load so if you try, do take care. 6v solenoids do not like 12v so suggest not having the solenoid in the circuit if you try.

You also need to make sure the motor is very well secured and clamped. If not, the torque could send it across the bench damaging something else or do damage to the motor if the wires attached to it were pulled and twisted violently.
