UTV500 no spark
« on: January 28, 2022, 01:02:07 PM »
Hey everyone maybe I’m just stuck on stupid but I’m troubleshooting a no spark on a UTV 500. I don’t know the year but I believe it’s a 2010. It’s been sitting about 10 years. I changed the ignition switch and starter solenoid which were both bad. Now when I crank it to start I get one spark then nothing. It seems to do this every time. Looking at the CDI box there are two plugs that go into it. I haven’t dealt with one that has two plugs so I’m unsure if I can unplug a kill switch wire from it. I have a portable CDI box I plugged in to the trigger coil and I get no spark at all. When testing the trigger coil I had a reading of 110 ohms and when cranking I had .2V AC. I haven’t done one of those tests in a long time but I’m pretty sure I got a correct. Anybody think the trigger coil is bad or is there something else I should be looking at? I’m unsure if theres actually a kill wire at the CDI on this machine. I also do not have a wiring diagram. That’s making this much more difficult

Any resolution on this ? I have the same single spark issue on a unit that has been sitting for over 3 years...
