INTRODUCTION
The Auto Charge 11HO Battery Charger is a compact completely automatic charger
designed for installation on vehicles with two batteries. Two separate charging circuits
monitor the charge requirements of each battery and charge each battery individually. A
current limiter protects the charger when charging deeply discharged batteries by limiting
the total charger output current. An ammeter provides continuous indication of the charger
output.
Construction of the Auto Charge 11HO is extremely rugged to withstand the shock and
vibration normally encountered by vehicle mounted equipment. The unit operates comÂpletely 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 11HO 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. Double check all wiring before proceeding.
4. Wire the A.C. power to the A.C. Input Terminal Strip.
5. Pilot light will light to show that the charger has power.
