The Kohler SV720 engine that was original to the tractor died with the previous owner. The owner then received, not sure if warranty or bought, a new replacement engine, not rebuilt.
The engine is the same as the original. The spec# XXXXX XXXXX and the serial # XXXXX XXXXX /p>
So to answer your question, this is a new motor. Mater of fact...I had to tap all hole on block for screws and bolt to complete assembly.
The tractor did not come with an oil pressure guage, but the owner did install a mechanical gauge that uses no power whatsoever. Which makes me wonder why the gree pressure switch wire was included in the wiring harness in the first place.
I used the service manual for the SV720 you sent me the link to to help me identify the wiring. According to the manual, the Electronic Ignition System comes in three flavors...(CD), (DSAI) or (DSAM). Judging by the diagrams in the service manual, and my wire harness, I think mine is the CD one...as the ignition modules have one single tab on one side and 2 tabs on the opposite side. The single tab will accept a connection whereas the side with two tabs will not as the tabs are welded/connected to the module with very little hanging over the edge to connect anything to.
I ask if the violet wire is the B+ wire that gets connected to the Rectifier Regulator because ALL EIS system diagrams show the violet charging wire being connected in the center position of the Rectifier Regulator.
I currently have the white wires connected to the ignition modules per the diagram, but am unsure how and or where to connect the violet and green wires.
