I just purchased a Leyland 154 (SN: 54D/301750/z 8727). I have several questions. The ignition switch is seized and key broken off. Does anyone have a good source for a replacement switch and/or good wiring diagram for the same?
I heard older ones can be positive ground; does the serial number date my tractor and if yes, can someone tell me if it is likely a negative or positive ground system? Thank you for the time.
