2013 KRF750S Teryx will not run.

marineengineer56 · July 8, 2019

Have a 2013 KRF750S Teryx that starts and runs 10-12 seconds and then shuts down. Also , notice the Multifunction Meter panel acts like it looses power. Turn the key off then back on, the Multifunction Meter panel starts up, then immediately shuts down. The machine needs to set for at least an hour before trying to start then shuts down again. [i.e. the symptoms repeat] I believe the ECU is failing but don't want to make a $500.00 mistake The service manual only addresses failing sensors, not the ECU. Any ideas on how to test if the ECU is failing? If it was a car/truck, my computer scanner will tell me.

It would lead me to believe a faulty Ignition Coil, but when you mention the Multifunction panel, sure sounds like the ECU to me. I don't how to test them, i would contact your local Kawasaki dealer or Kawasaki directly to see if there is a procedure for testing one.

Awaiting for new ECU to show up Tuesday the 16th. Contacted the local dealer, they said sure bring us the bike, pay $100.00 to Troubleshoot. if it's the ECU. pay $550.00 for a new part plus 1.5 Labor hours @ $95.00/hour. Said, nope, I will just replace it myself.

Yes, it was a combination of a bad ECU and Fuse Box Corrosion. Once the owner gets it started, runs fine. Now the issue is the battery is not charging. Replace the Rectifier, got 14 vdc on the battery. Now am only seeing 13 vdc. When I have time , gonna have to verify the alternator output. Then I am gonna have to make a new fuse box, can't buy one as you have to buy a complete wiring harness which is like $400.00 which the owner doesn't have.
