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!
