Lvk47, I thought I had posted this, but I guess not.
Take a D cell battery and connect the bottom to one of the leads to the drivers. Then just touch the top + of the battery to the other lead. If the driver moves forward that is the red or hot end. If it move backward, the lead to the + is actually the neutral.
Herman, what you say is contrary to my experience.
