Voltmeter

The voltmeter tells whether the battery
is charged or discharged. Check
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.

Tachometer

The tachometer indicates engine speed
it in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and over–revving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.
