Well I just bought the 5105 and it worked great till this morning. The tractor will sporadically not want to start. Funny thing is if you keep the key switch over in the start position the tractor stays running but as soon as you let the key drop back to the run position the tractor dies.
It will do this a few times them start no problem at all. I traced the problem to the wire going to the injection pump. When the tractor starts and dies the voltage stops going to the injection pump. When the tractor starts and runs correctly it keeps 12 volts to the injection pump.
The problem is I can’t figure out what is causing the power to go in and out to the injection pump. I haven’t been able to locate a wiring diagram anywhere. I assume there is a some type of relay going in and out or the key switch is going bad.
