Hello I bought an old lawn tractor with which the ignition lock was broken. I bought a universal thing now but I don’t know how to clamp it now. I wanted to ask if someone has a schematic or can tell me what the numbers stand for at the terminals. So with the terminals are the numbers 30, 15, 50, 83 and 75. Furthermore I would like to install a contact control light where do I have to put the between? Thanks already before!! oh yes for This is a Wheel Horse C 101 with a K241 engine.
