Hi. I have a 2014 750 King with Power steering. Just bought it June 2022 with 1200 miles. Yes 1200 miles and 110 hours. Goes dead for no reason. As suggested I unplugged the black wire coming out starter relay. Problem goes away.
Checked the wiring diagram. The W/D shows the wire goes from the starter motor side of the starter relay. The other end goes to terminal 12 on the ECU. So ECU pin 12 has 12.6 volts on it when the starter relay is energized. Why does the ECU need to know when the starter motor is energized? AND what does it have to do with the stalling problem? Maybe something to do with when the starter relay is deenergize terminal 12 on the ECU is effect grounded through the starter coil stator winding. I wonder what would happen put a diode to allow the ECU to see the 12.6 VDC when the starter is energized and blocks pin 12 from seeing ground . If the diode works, there is a programing problem in the ECU. Your thought are appreciated.
Thanks MKibbe! Would love to know what led you to unplug the wire. BTW if it is something overlooked in the programing, Don't expect Suzuki to fess up. David .
