Quoted from Bee-barf:Thanks HowardR, I got a stupid question: not sure what a thousands unit is, or a unit runout is. Is this in the armature, the score motor or score reel? Thanks.
The Thousands unit is the 1000 to 9000 point score reel and the schematic is referring to its solenoid. The 1000's Unit runout is one of (usually 3) switches on that score reel. You can identify which of the 3 by wire colors that are attached to it. Does that help?
