SERVICE MANUAL NUMBER 24
INSTRUMENTATION
Description
Lighting Options
Some gauges may be wired so that the illumination lighting is provided from the ignition
switch or a separate instrumentation lighting switch. By removing contact strip “I” from be-
tween + terminal and the screw as shown following, and supplying a separate +12 V power
supply to the screw connection, illumination lights can be operated independent of ignition
switch.
Other gauges are equipped with optional illumination lighting. Light bulb socket can be re-
moved and contacts can be aligned to be used with ignition switch lighting circuit +12 V or
separate instrumentation lighting circuit LT.
IMPORTANT: Light socket must be removed from gauge and turned counterclock-
wise (facing back of gauge) when adjusting to desired setting. Turning socket while
still installed in gauge could result in damage to gauge or socket.
NOTE: For different lighting effects, colored sleeves are available through the Quicksilver
Accessories and can be assembled to the bulb.
