Kawasaki Mule

Hi all, I run an independent service shop. I'm curious to know what y'all use for diagnostic tools. I'd like to find an 'agnostic' tool - something not tied to any one manufacturer and that I can use for any UTV/ATV/bike & snowmobile. I'm willing to pay a little more if it's a good one - something with automatic updates to stay current. Bonus if it comes with training on how to use it. Any ideas you can offer are appreciated. Thanks!

500s SxS won't start. Battery is good. The relays are clicking but will not turn over. It is cold here -10° Fahrenheit.  Looking for help to figure out what's going on. Thanks,

Can you fill us in from the start so we can help you properly? So I'm assuming (correct me if i'm wrong) you had a no start and decided to change that stuff? What exactly was it doing? It cranks over properly when you turn the key? What is the battery voltage before you try to start it?

I just ordered number 3. $120 with shipping, what a joke. Once it get it I will let everyone know if it works and is the updated shifter
