INTRODUCTION
The Auto Charge 12HO is Battery Charger is a compact completely automatic charger
designed for installation on vehicles with a single battery system. Remote sensing permits
long lines between the charger and the batteries by compensating for the voltage drop in
the charging wires. An ammeter provides continuous indication of the charger output.
Construction of the Auto Charge 12HO 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 12HO Automatic Battery Charger should be installed in an area with
adequate ventilation. A power cord is supplied for connection to 115 volts 60 Hz.
1. Mount the charger using the four holes provided for this.
2. Connect the wiring from the battery to the Output Terminal Strip. Spade lugs that
have been securely crimped, or soldered, should be used.
3. Double check all wiring before proceeding.
5. Wire the A.C. power line cord to 115 volts.
6. Pilot light will light to show that the charger has power.
