GMJGES
With the ignition switch in the ON or START posi­
tion, voltage is supplied to all gauges through the in­
strument cluster printed circuit. With the ignition
switch in the OFF position, voltage is not supplied to
the gauges. A gauge pointer may remain within the
gauge scale after the ignition switch is OFF. How-
' ever, the gauges do not accurately indicate any vehi­
cle condition unless the ignition switch is ON.
All gauges except the odometer are air core mag­
netic units. Two fixed electromagnetic coils are lo­
cated within the gauge. These coils are wrapped at
right angles to each other around a movable perma­
nent magnet. The movable magnet is suspended
within the coils on one end of a shaft. The gauge nee­
dle is attached to the other end of the shaft.
