I am in the process of changing the standard bulbs in my gauges to LED bulbs. On the 914-6, the far left gauge has the generator bulb that must stay as a filament bulb to keep the charging system working properly. I want to confirm that only the bulb behind the “G”, on the far right of the gauge, is the only bulb that must stay a standard bulb for the charging system to function properly. Can someone confirm for me.

I am also not sure what the indicator light to the left of the “G” indicates. Please chime in if you know.

The "G" light is the correct one for the charging system warning light.

The white circle inboard of that is a blank. In most 914s, it did nothing. In a few (approximately 25) 914-6es, it was a Sportomatic warning light of some kind. Possibly over-temperature?

On my 76 with presumably stock gauge, that white (actually kinda yellow) socket gets used for gauge illumination function.
Somewhere in a place i can no longer find is a list with images of all years combo gauges which was very helpful.

It used to be at http://p914.com/p914_gauges.htm but that site seems to be dead.

Web Archive is not happy today, either.
