Porsche 968 - Oil Pressure, Voltmeter, and Alternator Warnings; Oil Pressure Gauge and Warning; Voltmeter for Charging System; Alternator Warning Light

~ Oil Pressure Gauge
Oil pressure should be approx. 4 bar at 5000
rpm, with the engine at normal operating tem-
perature. A drop in oil pressure at high tempera-
tures is normal. •
However , if oil pressure drops suddenly while
you are driving, or if the red warning light
comes on, stop the engine immediately.
If the oil level is normal , contact the nearest Offi-
cial Porsche Centre in order to have the fault
rectified.

Warning Light
The oil pressure warning light comes on when
the ignition is turned on, and goes out when the
engine is running and the correct oil pressure
has been reached. If the light comes on while
driving, this is a sign that oil pressure is incor -
rect.
If this happens, stop the vehicle immediately.
If the oil level is correct you should consult the
nearest Official Porsche Centre in order to deter-
mine and rectify the fault. An occasional , brief
flickering of the warning light when the engine is
hot , at idle speed, is normal and no cause for
concern.
t:3 Voltmeter
The voltmeter shows the overall condition of the
charging system. The needle should normally
stay in the range of 12 to 14 volts when the
engine is running . A temporary drop under 12
volts when the engine is started is normal.
Alternator Warning Light
The alternator warning light monitors the alterna-
tor and its drive belt. It comes on when the igni-
tion is turned on, and goes out when the engine
is running . If the warning light suddenly flickers
or burns steadily while driving, the drive belt
may be loose or broken, and must be retight-
ened or replaced. Alternatively, the problem may
involve the voltage regulator or the alternator it-
self; in such cases it is possible to keep driving,
but preferably only as far as the next Official
Porsche Centre. Switch off all electrical equip-
ment that is not absolutely essential!
