So I recently picked up a 2012 mahindra 3016 hst, whoever owned it previously seemed to have had an issue with one of the starting interlocks, because they just installed a push button to the starter solenoid that's hot all the time to start the tractor. The power to ignition circuit still works correctly through the key switch, just not sure what interlocks I should be looking for to ohm out to locate the problem and put it back to factory. If anyone has a wiring diagram of the starting circuit that would be a huge help. Thanks in advance.
