CIRCUIT INSPECTION
Entire combination meter does not operate
CIRCUIT DESCRIPTION
This is the power source circuit of the combination meter.
The combination meter uses BEAN to determine that the ignition switch is in the ACC position or not.
The ST terminal (C5–3) is used as an auxiliary power source to prevent voltage drop when the ignition switch
is ON. When the ST terminal circuit is open or shorted, the combination meter illumination may flicker when
cranking the engine.
