I'm trying to help a friend get his 2240 running. I found out the circuit breaker needs to be replaced but there is something else wrong in the starting circuit. The tractor will start if you jumper the starter solenoid. He told me the tractor would start fine in the morning but after he had been running it a while and shut it off and then tried to restart it shortly after, it wouldn't start unless he jumped the starter solenoid. While doing this on one occasion is when he blew out the circuit breaker because before that the gauges worked but now they don't and they are powered through the circuit breaker.
I don't know what year the tractor is but the attached schematic doesn't seem to agree with some of the wiring. Does someone have the next page to it that tells what the part numbering refers to? Coming off of the Start terminal on the key switch the wiring goes to #10 and then to a relay #14. Does anyone know where the #14 relay is located and what the #10 is? I'd really like to find out what all of the components are which is why I'm asking for the next sheet that would give their descriptions.
Before I got involved he took out what I think is the PTO sensor that is located right below the PTO engagement control lever. This sensor screws into the front of the transmission cover that the shift levers and PTO control come through. We can't get it to thread back into the hole since there is so little clearance to get you fingers into to turn it. There is a spring that fits over the end of it that gets screwed into the cover and only one electrical connection to it on the outside. This sensor appears to be a solid rod, threaded on the outside for the electrical connection, with a plastic outer case that screws into the cover. The coil spring slides over the piece of the rod that goes into the case. The spring is about twice the length of the part of the rod it slides over. If this sensor is supposed to provide a ground path for a signal when the PTO lever is in a certain position what keeps the spring from providing this path all of the time? Is this sensor supposed to be #9 in the schematic? #9 has two wiring connections but the sensor I'm dealing with only has one.
Last question is about the PTO lever. Before he removed the above sensor he could pull up on the PTO control knob and it would stay up but since he took the sensor out the lever won't stay in the up position and just drops down. The spring on the sensor doesn't seem to be strong enough to hold the PTO lever in the up position, if that is what it is supposed to do. Does it sound like we have to remove the transmission cover to find out why this happened. We may have to remove it to get the pita sensor back in! Any help would be greatly appreciated
