Kubota L4310 HST
Good Evening....new member here, thought I may find some help. My Kubota L4310 was running fine, when I came in to refuel and tried to restart I got nothing. The glow plugs and lights all work but it won't turn over. I just hear one audible click when turning the ignition to start. The battery tested good (it's fairly new), starter/selonoid and ignition all test good with my multimeter. So now I'm thinking it may be a starter relay. I also haven't checked the safety switches, I'm not really sure where to find them. Any help would be appreciated!

Remove, inspect, and clean all high current cables. That includes the ground strap to the frame, starter connections, and battery terminals. If that doesn't get you going, load test the battery regardless of its age.
You can also test the voltage getting to the starter solenoid upon activating the key. Low voltage may indicate resistance through the various safety switches or the key switch itself.

I’d first check to see if you bumped the PTO on by mistake, or some other control that prevents starting.
