Here's the '47 Delco Remy ignition switch(FRONT & BACK). It's a two-postion switch: OFF and ON. There are three terminals on the back: presumably a battery terminal, ignition terminal and an accessory terminal. Does anyone know what terminal is the battery terminal? The IGN and ACC terminals are supposed to be 'hot' in the run (ON) position. I've done some testing with my ohm meter and get the same functionality regardless of which terminal I use as the BATT. Maybe it doesn't matter, but it would be nice to know it is correct...........
