Hi  Guys, looking to purchase an '84 K100 this week. However, I'm a tad concerned about the permanent neutral light on display. I am assured the bike runs A1 through all gears. The gear select indicator works ok. The owner suggests the gear sensor/indicator switch may need replacing. Would a broken gear sensor be consistent with this problem? I'm thinking a broken neutral wire on loom or faulty instrument panel.
Any help much appreciated.

If you see the gears in the indicator, the sensor is good.
It's somewhere in the instrument cluster where the defect finds place.

Ahh, thanks for that. I did think it strange. This should not inhibit my plans as I intend changing the clocks. Much appreciated.

The bugger seems to be 1 of these 3, or all....

Arlina from what you say am i right to think that if the gear indicator and neutral light stop working intermittently its most likely the gear indicator switch at fault.  Not the panel.

Ady mentioned the indicator works....


If the indicator and light don't work, or not normal, it could be the gearselector, but better start cleaning the connector on the right side.
