purchased a new kohler replacement mower and the electrical connections do not match.New motor is CH680-3107Old motor is CH22S-66542New motor has a 5 prong male connectorOld motor has a 4 prong male connector
Expert:  Curtis B. replied 8 months ago.

Service manual fr both models are in the same manual. starting with page 33. Did new engine come with any kind of wiring diagram? WHat is the source of the fifth wire, that is not on the old engine? Fuel solenoid, or maybe oil pressure switch?

Customer: replied 8 months ago.
No wiring diagram on new motor. Think the 5th may be fuel shut off at carb. Have been on Kohler site. Need to know how to direct wire
Expert:  Curtis B. replied 8 months ago.

Old engine did not have fuel solenoid? Fuel solenoid would wire to accessory post of the keyswitch, on with key on, off with key off.

Customer: replied 8 months ago.
I would need to confirm that. Unfortunately traveling for work and will not be back until tomorrow

By looking at wiring diagram on Kohler website can you tell me what new wires are. I can trace wires on mower
Expert:  Curtis B. replied 8 months ago.

What is model application? You want me to tell you where the wires on the new motor go to? 5 wires, where is voltage regulator? On new engine or on tractor? Two wires on engine are the stator wires for voltage regulator , one wire for afterfire solenoid on the carburetor, One wire for starter terminal, and one wire for power to the keyswitch through a fuse. Stator wires both will be same color, Afterfire solenod will have its own color, as well as the two wires coming from the starter solenoid. Go by wire color!

Can you call me or I call you
Expert:  Curtis B. replied 8 months ago.

white wire, from start terminal on the starter, has to go to start terminal on keyswitch.-------------------------red wire, is the fuel solenoid in the carburetor. --------------------------------------------------------------------Green wire, oil pressure switch. -------------------------------------------------------------------------------------Blue wire, shows to be same as the red wire.??-------------------------------------------------------

Purple wire , output from the voltage regulator , to the battery positive to charge the battery. This is using the fixed timing wiring diagram.

Expert:  Curtis B. replied 8 months ago.

Phone call is extra charge and I don't know what good it would. You have to determine what each wire does, and make the right connection.
