The instrument panel holds various gauges at a

glareless, easy-to-read angle (Figure 3-1). The panel

contains:

The ammeter is connected into the main battery

circuit and indicates whether current is flowing

into or out of the battery. A needle deflection to

the CHARGE side indicates that the battery is

being charged by the alternator, and a deflection

to the DISCHARGE side indicates that the

battery is discharging, Normally, the rate will be

high for a short time after starting the engine,

then the indicator will return to a point slightly

above zero after a few minutes operation.

However, if battery is in a rundown condition,

charge rate may be high for some time. If

ammeter indicates DISCHARGE when engine is

operated above idle speed, alternator is not

producing current, or there may be a short in the

wiring system. Investigate and repair at once.
