Good point Dellbert, back at Purdue many moons ago we used the conventions of Conventional Current flowed from Pos to Neg (like outside the battery) while Electron Current (like inside the battery) flowed Neg to Pos. I tried to teach my kids when they studied science theres no such thing as voltage on a single point theres a voltage potential difference BETWEEN TWO POINTS and its between them current seeks a path to flow. The higher the voltage the worse the curent really wants to flow. I certainly agree the tractor DC starters turn the same direction regardless of polarity cuz youre not reversing the relative N/S polarities of the Field versus the Armature. However in those light cheap low torque permanent magnet motors (dont use a current induced electromagnetic Field) if polarity were reversed they indeded would run bass ackwards. I love this sparky chat John T
