So purchased an IH 574 a couple of years ago. Upon purchase the key switch was non functional, as well as all the lights, and gauges except tach. Makes sense, given it is mechanical drive. Previous owner had installed a push button start. u106k serial range.
Starts and runs well, but has basically been sitting while I did some routine maintenance and gotten around to fixing the wiring.
It has wiring for the 3 wire alternator, but only 1 wire is hooked up. Guessing previous owner installed a 1 wire alternator.
Got a key switch on the way to replace the current one, and I also noted back inside the instrument cluster area a broken junction block, so that will be replaced.
Question is, is it possible the 1 wire alternator, key switch being non op, and this junction block causing my issue? My thought from reading the wiring diagram, is that light and gauge power comes from the keyswitch, so if it is "off" as far as the tractor is concerned no power will flow.
Thanks,
