Origin Kit D5 - old type

After struggling for months with my old Centurion gate not stopping and hitting the end points at full speed, I ordered the replacement sensor kit, which seems to fix the problem. Before ordering, please check the following first: * Battery not old or low: Dips in battery voltage under load can sometimes cause the sensors to not trigger. * The teeth on the rotation sensor gear is clean and free of mud / grease. This can cause the rotation sensor to slip and lose count, causing the gate to stop too late.
