We purchased this UTV less than 60 days ago and now I am having issues with drained battery. Used UTV for about an hour then stopped and when I went to start back up my battery was to low to start it. Jumped it and it started right up and ran fine back home. Tested charging and it’s not charging while running. Can it be anything other than the stater??? Can I look for something that I can fix Quik or does it have to go to the authorized service center to stay under warranty? It will take some time to get it in and out of service
My 2018 Massimo MSU 500 was operating just fine. I parked it for 2 weeks in my shop now the unit starts and runs great but at 18 MPH it cuts out. It's not the seatbelt safety switch that engages at 10 MPH if it is unbuckled. I purchased a new ECU but that did not resolve the problem. No error code is presented. I reset the ECU replaced the fuel injector, coil, sparkplug and spark plug wire. Same response. I don't mind replacing faulty components but don't want to chase parts and hope for the best. Any ideas??
I parked my 2018 Massimo MSU500 in a clean shop for two weeks. When I brought it out for routine ranch work it started cutting out at 18MPH. It's not the seatbelt safety switch, if the belt is not buckled that engages at 10 MPH. I replaced the ECU, fuel injector, coil, plug wire and spark plug. No error code is presented. I put the original ECU back in and reset it then adjusted the idle to 1800 rpm. I don't mind replacing faulty components but don't want to blindly parts chase hoping for the best. Does anyone have experience with a similar situation??
I have a fuel injected UT400 that will start and idle, but surges and sputters at higher speed. It has been sitting for 2-3 months and was fine when parked in garage. I assumed it was a fuel/air problem and pulled the throttle body and cleaned it up. I've ended up replacing the injector, IAC valve, MAF Temp Pressure Sensor, and fuel filter. I've also checked the spark plug, Still surging. I reset the ECU after every component swap.
I plan to pull the throttle body again and look evrything over for any visible leaks, etc.
Any suggestions would be appreciated on next steps. The problem developing after sitting makes me think it should be something simple, but I'm stumped. BTW the fuel was fresh and treated with Stabil.
