Primary winding (power) ~4 ohms (no diode)
Secondary winding (hold) ~132 ohms (no diode)
Williams / Bally pinball machines flippers are designed for a balance of power based on the layout of a given game. Always use the specified coil number for your machine. Always install a flipper rebuild kit before changing coils (see related items below). The factory recommends a complete flipper rebuild every 500,000 cycles or flips. But, if you must adjust flipper strength, here is a list of coil numbers and their relative strength going from weakest to strongest:
FL-11753 Yellow - Used with short flippers and close shots
FL-11722 Green - Used for close shots near drop targets
FL-11630 Red - The standard, most commonly used coil
FL-15411 Orange - Used for long playfield shots
FL-11629 Blue - Used for long shots and high ramps
