The ignition switch has a jumper across the contacts where the old heating coil indicator used to connect to and supplies 12V to the glow plugs. This comes as a good reminder for me to finish up the 1772 schematic I've got partially done that includes the timer and light bulb circuitry that Cub Cadet left off. I only have 1 or 2 more connections to trace off of the ignition switch.

Thanks for correcting me. I was not aware the 1772 had a different glow plug schematic.
