Old motor question

I have an old metalist. motor sets in line with the cart. Motor has 4 terminals in a row. They are A1A2F1F2. I took all wires off motor made a jumper from A2 to F1 applied 12 volts to A1 and F2 the motor run in reverse. I change pos. and Neg. and the motor still runs in reverse. What is wrong??
Sorry I've never had a motor do this before.
