I acquired a 15hp Briggs & Stratton John Deere Sabre mower. The wiring harness was a mess. I can't find a wiring diagram that fits this model. I have it rewired cranking and running on its own. The only question I have is how to connect the alternator. While it is on high throttle its doing a little over 18 volts. Does that wire go straight to the battery or does it need to go thru something else before?
Briggs Alternator wiring?

Okay you have the dual stator. The one with the diode lump (probably the red wire) is the DC output and the other is AC output for the lights. The DC is an unregulated 3 amp output that connects direct to the battery via battery cable at the starter solenoid. On some equipment it is ran through the ignition switch but not always. Both of these wires reference frame ground. so don't connect together.
Does the red wire end in a bullet connector? If so it should have the diode. Maybe it has been cut off, you then need to add the diode which is available at an electronics supplier. The other option is replacing the alternator which gets expensive. Give us the engine numbers so we can see what you are looking at.
