INTRODUCTION
The Auto Charge 20 Battery Charger is a compact completely automatic charger designed
for installation on vehicles with three batteries. Three individual chargers are provided to
charge the three batteries. Voltage is sensed separately for each battery so that each battery
is charged according to its requirements. The total output to the three batteries is 20
amperes. An ammeter provides continuous indication of the charger output.
Construction of the Auto Charge 20 is extremely rugged to withstand the shock and vibration
normally encountered by vehicle mounted equipment. The unit operates completely
automatically and stops charging the batteries when they are fully charged. There is no
trickle charge and therefore no danger of overcharging and water boil-off. Any parasitic
loads on the battery such as radio, lights, etc., are automatically supplied with current by
the charger.
INSTALLATION
The Auto Charge 20 Automatic Battery Charger should be installed in an area with adequate
ventilation.
1. Mount the charger using the four holes provided for this.
2. Connect the wiring from the batteries to the Output Terminal Strip.
3. Connect the wiring to the batteries. Ring lugs that have been securely crimped, or
soldered, should be used.
4. Double check all wiring before proceeding.
5. Wire the A.C. power to power input terminal strip.
6. Pilot light will light to show that the charger has power.
