Hello JDH, if you have followed the steps I mentioned, can you please let me know what transformer you’re using? I use a vintage Lionel 275W ZW. The problem you mentioning can be caused by a lack of voltage. The pendulum units work best at higher than usual voltage. If your transformer has a dedicated direction switch set your throttle at around 10V or above and just use your direction switch to cycle the reverse unit. That may solve your issue. Lubrication shouldn’t be needed unless the switch didn’t cycle smoothly when manually tested with a screwdriver pressing on the actuator arm.
