Does anyone know if the 172M engine and fuel gauges are internally illuminated? The POH says that it is supposed to be, and that it’s controlled by a rheostat.
The maintenance manual however does not address it. The wiring schematic doesn’t show any wiring that connects these instruments to a rheostat, or any other source for lighting.
Looking at the back of the gauges I see absolutely nothing that indicates a way to power internal lighting, or that any internal lighting even exists.
If anyone has this same cluster (see pic) I’d like to know if yours has an internal lighting or not.
Thanks.
