I'm an Ag. teacher in Tennessee, and my students recently finished a Super M restoration--they did 98% of the work, and did a great job. In redoing the wiring harness, we followed a plan from this site that referenced a SM 12-volt conversion. After doing everything (or so I think)by the schematic and directions, the tractor does start and run, but won't shut off. The only difference between this tractor and the schematic is the use of a three position switch instead of the "push-pull" switch to shut it off. The tractor will not start with the switch in the off position, but it will continue to run once started with the switch off. Where the switch is marked "coil" the coil wires are attached, and where the switch is marked "AMM" the wire coming off the ammeter is attached. The third position marked "AC" is empty. I ran a continuity test on the switch, it check outs as being open in the off position, and showing a closed circuit in the on position (.2 ohm is what the multimeter read as I remember) Any ideas? Thanks in advance for your time and help, my kids and I appreciate it.
