Here’s a new one. We see a lot of ATVs, UTVs, and motorcycles that won’t start, but what happens when your ATV won’t turn off? We’ve already done a deep dive into the starting system on our Yamaha YFM700 Grizzly, and during our work we realized that the unit would not shut down completely and the battery kept getting drained.
John will show you how to inspect the ECU for water intrusion and look around on the wiring harnesses for another possibly culprit: exposed wires that close a new circuit. On our unit, that was the case and we’ll show you how to replace the ignition switch on your Yamaha Grizzly.
