The gear position switch is a simple rotary switch with 6 contacts inside. It is mechanically rotated by the gear shift drum. If it displays the same gear position (4) as you shift normally, the switch is simply not turning. It is not a wiring problem or a short or open.
It relies on a little roll pin pressed perpendicularly into the rotating shaft of the switch, which aligns with a slot in the end of the shift shaft. When the switch is installed at the factory, it must be aligned by eye before bolting it in place. It is easy to get it miss-aligned, which could bend or break the roll pin.
The switch is underneath the sprocket cover.
