How do you tell if your starter is converted to 12 V

[alexa]

I have a starter from an automatic and decided to use the casing to build one for my straight stick. I took apart an old starter I had to convert it. The casing in the old starter had the same two coils as in the 12 volt version! I measured resistance etc and all was the same. Does this mean I already had a converted starter and did not know it? One other starter I have has 4 coils inside the casing.....

Alex, The 2-coil is for the Std-Trans and the 4-coil is for the Auto. Trans.
(i think) It takes more H.P.to turn the engine due to the Heavy-Converter.
The wire used in the 12-volt starter is smaller gauge that the 6-volt starter even if it is a 2-coil. (look at the windings,the wire should be thiner in the 12-volt)
Before converting to 12-volts we did an OLD-TRICK that we used in the old CAT-Tractors. We removed the coils from the case,thenwe removed a complete turn of the wire from each coil being carful not to brake the Paper-S eperator that is between each winding . (insulating tape)
This will spin the 6-volt starter as if you had an 8-9 volt Batt connected to it.
Less wire in the coils means faster speeds and just as much power.
It workes. Hope this Helps. Rudy
