My M5-111 will start but for the most part it won’t start or do anything. When it does crank I can’t get it to crank again. It’s weird how it will start when it wants to. When it doesn’t start I don’t even hear the click of the fuel pump. It acts like it’s in gear or the PTO might still be on. Even though it’s not. I can only speculate that it’s a safety switch, the gear and clutch is out of sync or the ground wire could be corroded. Even though the ground wire looks fine. The battery is still good. So what are my best options to find out what the problem and fix is?
