AMMETER

11.4

The Ammeter indicates the amount of current measured in amperes that

is being drawn by the battery. For example, in the 40 amp charge rate a

typical discharged battery will initially draw approximately 40 amps. As

the battery continues to charge, current will taper to 15 to 20 amps at full

charge. The Start area of the meter indicates a high rate of current be-

ing drawn from the charger. When cranking an engine, the starter motor

draws upwards to 200-300 amps. The meter needle will be at the extreme

right side of the start area. Sometimes a battery for the first few minutes

of its charge will draw more than 70 amps, in this case the needle may

be within, but not all the way over, to the right side of the start area. The 4

amp charge rate may indicate some activity on the meter. The meter does

not have the resolution to display this low rate.
vOLTMETER

11.5

The Voltmeter indicates the voltage at the battery terminals. Use as fol-

lows:

The charger need not be plugged into an AC outlet. The timer should

be in the OFF position. Then connect the charger following instructions

in Sections 6 and 7.

Observe the meter indication. Keep in mind that this reading is only a

battery voltage reading, a false surface charge may mislead you. We

suggest that you turn on your headlights for a couple of minutes before

you read the meter. Read a couple of minutes after you have shut the

headlights off. If the reading is less than 10.5-volts, the battery may be

bad or the connections at the charger may be poor. If the reading is

10.5-volts to 12.8-volts the battery is low – recharge it. If the reading is

above 12.8-volts the battery is charged.

ENGINE START

12.

Set the charge rate switch and the timer to the OFF positions.

12.1

With the charger unplugged from the AC outlet, connect the charger to the

12.2

battery following instructions given in section 6.
Plug the charger AC power cord into the AC outlet, and then move the

12.3

timer from OFF to the HOLD position.
Set the amp rate selector switch to the engine start position and then

12.4

crank the engine until it starts or 5 seconds passes.
NOTE: During extremely cold weather, or if the battery is under 2 volts,

charge the battery for five minutes before cranking the engine.
If the engine fails to start, charge the battery for 5 more minutes before

12.5

attempting to crank the engine again.
After the engine starts, move the amp rate selector switch to OFF and

12.6

unplug the AC power cord from the outlet before disconnecting the battery

clamps.
