/ Kohler to Briggs wiring issue #1

I've swapped a Briggs into my Cub Cadet XT1 which had blown the original Kohler Courage 18hp engine. The Briggs is out of a Craftsman riding mower, it's a 15.5HP Turbo Cool model 28U707. It starts and runs but the fuse at the + battery post is blowing, so will not start again untill the fuse is replaced. So apparently I've got something wrong. The original wiring on the Kohler had the violet wire running to a "rectifier-regulator" which then had the two wires from the stator connected to it. The only other wires on the engine side that were connected were the fuel solonoid on the carb and the ignition module. The Craftsman with the Briggs had 4 wires on the engine side, the same fuel and ignition connections, but the wires from the stator went back into the harness back to the ignition switch. This is where I believe my error is. According to the Briggs schematic, there is an orange and red wire coming from the "alternator/stator", the red with a diode inline that reads charging system output 3 amp DC. Supposedly an orange wire that is labeled, " lighting system output 5 amp AC @ 3600 rpm/ 14 volts AC min @ 3600 rpm (lights off), but I have a red and BLACK wire coming from the stator. When the Briggs is plugged into the Craftsman harness the red wire from the stator is connected to an orange wire going back to the ignition. So my "guess" was to connect my violet wire to the red wire with the diode inline. I'm now assuming that was wrong. I did not visually verify if there was a diode and which wire it was on, only went by schematic. Tried to remove flywheel but wasn't having any luck. Tried to attach the schematics, but couldn't figure out how, kept getting a "file too large" message. I can't seem to be able to find any "Help" section on this forum.
