INTRODUCTION
The Auto Charge 12VHO 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 12VHO 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 12VHO Automatic Battery Charger should be installed in an area with
adequate ventilation. A power cord is supplied for connection to A.C..
1. Mount the charger using the four holes provided for this.
2. Connect the wiring from the battery to the Output Terminal Strip. Strip the wire insulation
approximately 3/8".
3. Double check all wiring before proceeding.
5. Wire the A.C. power.
6. Pilot light will light to show that the charger has power.

IMPORTANT: Each lead wire shall not be
greater than 20 feet for the charger to
deliver the full 20 amp output. If wiring is
to be longer, consult the factory for additional information.
NOTE: The sense leads must be
connected to the battery system as shown
for the charger to operate. A simple
check can be made as follows see
example:
EXAMPLE: Assuming a 24 VDC battery
system, the positive sense lead must
read approximately +24 VDC with respect
to the negative sense lead at the charger.
The battery “+” terminal must read
approximately +24 VDC with respect to
the battery “-” terminal at the charger.
These measurements shall be made
before the AC power to the charger is
applied.
