I have an Lt2000-50 Dixie Chopper mower. It had a CV20S-65594 kohler engine. It burned up in a fuel fire. The intended replacement for that engine is CV640-3039. I didn't buy that. I found a Cv730-3111 kohler designed for a dixie chopper also. I figured it was a power upgrade, and a little cheaper. It fits in perfectly but it has a slightly different wiring harnesses. I think also some wires burned off the old engine completely so I am trying to figure out what the lay out was for the cv20s-65549. I have looked at the diagrams from kohler and I think I know what is going on but I would love to see a few pics from an actual motor of the wires and where they go since I only have the end of the wires that go into the plug to connect to the mower wiring harness. Any help sorting this out would be highly appreciated.
Maybe this will help? On the ENGINE side of the main electrical connector Kohler used to use these wire colors as standard, Maybe your engine does too? But yours may be different but each function will be close to the same no matter what color the wires are. You need a volt ohm meter or at the minimum a 12V test light to do this correctly.
Red - 12V Power input from switch to threaded post on starter. Usually with an inline 30 amp fuse. 12V. continuity with ign. switch in Run and Start position.
Goes to "B" terminal on Ign. Switch
Purple - B+ from center terminal of regulator/rectifier. Goes to Positive terminal of Battery. this is the battery charging lead from Reg./Rec.
Goes to "R" Terminal on Ign. Switch. Will have 12V Continuity in Run and maybe in Start position on Ign. Switch
Blue - Starter trip wire to tab terminal on starter solenoid Goes to "S" terminal on Ign. Switch. 12V continuity in Start position only on Ign. Switch. This circuit could also go through a safety interlock switch arrangement?
White - Kill lead for Ign. Module goes to "M" terminal. Continuity to Ground with switch in Off position. This circuit could go through a safety interlock switch arrangement also?
Yellow - (If Equipped) Switched 12V Accessory. Goes to "A" terminal on Ign. Switch This is not a mandatory circuit but may be used for lights or Safety circuit etc. on mower?
