Voltage regulator for 12v S/G

Recommended Posts


In the past there were discussions about what regulator will work with the S/G, but was not able to find anything.   After extensive testing I believe my voltage regulator is bad.   What regulators will work with the Starter Generator?

Mine currently has 3 posts (Arm, Field, Bat).

When I ground the Field I do get a quick flash of 20amps for just a second or two.   I checked another tractor that I know charges and I get the same thing (just a flash when I ground out the "F" terminal).  But following the book I do not get any amperage.

One of the Simplicity delco numbers was 1119310E.  

I believe Cub Cadet voltage regulators would also work since the S/G is the same.

See this recent post for some other suggestions:


Another post referenced the Delco 1118988 regulator.
