Hello everyone, I have a 2240 and the tachometer doesn't work exactly. The rest of the dash works, fuel,temp, hour meter, lights. The only problem is that the tach says I am pulling 2000 rpm even when I'm idling, its got power but it goes to 2000 rpm and doesn't move off unless I really get on it and then it moves up 100-200 rpm. I bought the tractor like this assuming since it had power it would be something simple but after looking at it I found out the system is a more complicated that I thought. I didn't want to drive an hour to the nearest dealer so I was hoping someone on here had a schematic or some help as to what the problem might be and how to fix it. Thanks in advance.
