w: The 'Premium Unleaded Fuel Only' caution is added to the Federal Market vehicles, also 'PARK BRAKE and
'BRAKE' replace international symbols used in all other markets.
m: Six cylinder vehicle version shown; the tachometer red-line on 12 cylinder vehicles starts at 6000 RPM.
The front of the
PECUSprogrammable instrument panel features 6 analog gauges, 22 warning lamps /tell tales and
a Liquid Crystal Display (LCD), the rear of the panel accommodates two PCB mounted connectors, one 24-way
connector, one 48-way connector, one instrument panel identification label and 14 light bulbs arranged in groups of
seven on either side. Three power inputs and two ground inputs are provided for 'POWER UP' and 'POWER DOWN'
sequence, the three power inputs comprising battery, ignition and auxiliary. The instruments are protected by a
housing
/ lens assembly.
15.2.7 Gauges
The two major gauges are tachometer and speedometer, and the four minor gauges indicate battery condition, fuel
level, oil pressure and coolant temperature.
Each gauge is contained
in a sealed non-serviceable can and must be renewed as a complete unit in case of any
damage.
CAUTION: Extreme care should be exercised when renewing instrument pand components to avoid damago to the delicate indicator needles.
