INTRODUCTION
The Auto Charge 12HO Battery Charger is a compact completely automatic charger designed
for installation on vehicles with a single battery system. The patented "sample & hold" circuit
is utilized to detect the battery voltage via the charging cables . 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 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 12HO Automatic Battery Charger should be installed in an area with
adequate ventilation. A power terminal is supplied for connection to AC.
1. Mount the charger using the four holes located in the front and rear of the charger.
2. Connect the wiring from the battery 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.Check the position of the Voltage Selector Switch and wire the VAC input power line to the
power source.
6. Pilot light will light to show that the charger has power.
