Meter Illumination is Always Dark: Description

The combination meter sub-assembly receives signals from this circuit to adjust the illumination of the meter. The combination meter sub-assembly sets the illumination level based on the user operation of the light control rheostat.

HINT: 

• The meter illumination level can be adjusted by operating the light control rheostat.
• The meter illumination dims when the light control switch is turned to the tail, head, or AUTO position at night.
• Setting the meter illumination to maximum brightness cancels the above dimming of the meter illumination.
