Troubleshooting tip: The primary and secondary windings on this coil are connected in series, while most other flipper coils are wired in parallel.
If your flippers are weak, ensure that your end-of-stroke switches are of the tungsten high-current type and set so that they are normally open when the coil is at rest. These coils are designed to add the holding coil to the circuit, increasing resistance and reducing current at the end of the flipper stroke.
