I have an older Belarus tractor that has always been difficult to start on the electrical side of things. I have found loose wires here and there over the years, but a new problem is that when I turn the key I hear a click in the solenoid and the cable running to the starter gets hot, but it takes several attempts and me thumping on the starter with a 2x4 to get her to turn over slowly- she always starts if I can get her to turn over. I just replaced the batteries with new 2 months back and keep them charged up. Any suggestions are appreciated. Please dont tell me to get rid of the Belarus as it isnt an option at this point. Could it be the starter or the engine seizing up? Im not much of a mechanic.
