Hi Gerald, thanks for the reply. I have a quick question though. You mention something about field core saturation; would this show up as a field coil with a lot larger core for the 12V field coil than for the 6V?
Now, the field coils on the old 6V unit show 1.9 ohm resistance across both coils, the questionable unit has new field coils, I didn't want to start cutting covering but they test 6.9 ohms across both coils.
Now for the rotor. The 6V armature windings are about half the wire diameter of the questionable (12V?) unit's windings and not the other way around. (Number for the original 6V rotor is 853593- I cannot see a full number for the "12 V" unit). Are you sure that the rotor windings are supposed to be smaller diameter for the 12 V unit?
Actually the starter is in a pretty good way. Overhaul with bushings and brushes and a new contactor-bendix was excellent. I have good cables on the tractor, a special thick tractor "hot" cable from the battery to the starter contactor and a thick ground strap. All connections are filed and greased. Bypassing the tractor ground with jumper cables grounding directly to the starter makes no difference.
When that starter is hit with 12V it cranks the engine like a BMW. With 6V I can't get the engine to turn through a complete revolution. Fortunately this is enough if the engine is stone cold, it fires right off.
As for the battery size, this is an Allis B and it has a pretty small battery box mounted beneath the steering column (original box, too) and there is really just no way to mount a larger battery, anywhere.
Changing bulbs is minor, as I have a magneto system, I won't need to fool with a new coil.
