I have a 2001 Toro 268H that had a Kohler CV18S in it that threw a rod. I picked up a CV20S to replace it with. I'm used to my older 520 and 416 Onans, these Kohlers are foreign to me!  ;-)  I'm going to replace the starter as the donor uses an external solenoid, and the old one had it all on the starter, this way I can use the factory wiring with less issues. The bigger issue is that there is no external voltage regulator on this one, the 18 had one? There is a "cover" where the regulator would be and a two-wire black and yellow wire coming out the back of the motor, anyone have an idea what that is?

 

Not sure how to complete the charge system on this swap.

Don't see a regulator on the CV20

If the CV18 has a spec #61528

Hopefully you can swap the flywheel and stator.

 

Page 40 of this manual shows a 3amp charging system which is likely what the CV20 has. Yellow and black stator leads are identified.
