Charging System Light

This light should come on

brieﬂy when you turn on

the ignition, before starting

the engine, as a check

to show you it is working.

After the engine starts, the light should go out. If it stays

on or comes on while you are driving, you may have

a problem with your charging system. It could indicate a

problem with the generator drive belt, or some other

charging system problem. Have it checked right away.

Driving while this light is on could drain your battery.

If you must drive a short distance with this light

on, it helps to turn off all your accessories, such as

the radio and air conditioner.

Voltmeter Gage

When your engine is not

running, but the ignition is

on (in the RUN position),

the gage shows your

battery’s state of charge

in DC volts.

When the engine is running, the gage shows the

condition of the charging system. Readings between

the low and high warning zones indicate the normal

operating range.

Readings in the low warning zone may occur when a

large number of electrical accessories are operating in

the vehicle and the engine is left at an idle for an

extended period. This condition is normal since the

charging system is not able to provide full power

at engine idle. As engine speeds are increased, this

condition should correct itself as higher engine speeds

allow the charging system to create maximum power.
