INTRODUCTION
The Auto Charge 20/20 is a compact 20 ampere completely automatic battery charger
combined with a 20 ampere Battery Saver 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. The Battery Saver provides 20
amperes of current to power 12 volt accessories whenever the vehicle is connected to A.C.
power. Ammeters are provided to indicate charger and Battery Saver output currents.
Construction of the Auto Charge 20/20 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. Parasitic loads from the
vehicle should be connected to the Battery Saver. These loads will be connected to the battery
when the vehicle is in use but are removed automatically when shore power is supplied and are
then powered by the Battery Saver power supply.
INSTALLATION
The Auto Charge 20/20 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.
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.
