Introduction
The ProXtra is a revolutionary product specifically designed to enhance trolling
battery performance and extend the amount of battery power available to the
user between charge cycles accomplished with a conventional battery charger.
This system utilizes boat engine charging current to charge your trolling motor
batteries while the engine is running. Solid state electronics ensure that the main
starting battery is adequately charged before allowing current to flow to the
trolling motor batteries. The ProXtra is fully protected against short circuits and
reverse polarity and is not directly connected to the ignition system or engine.

IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS. This manual contains important safety and
operating instructions for the ProXtra 1, ProXtra 2, and ProXtra 3.
Use of attachments not recommended or sold by PCS may result in a risk of fire,
electrical shock, or personal injury.
Do not operate unit if it has received a sharp blow, been dropped, or been
otherwise damaged in any way; contact technical support at PCS (800.742.2740).
Do not disassemble unit; contact technical support when service or repair is
required (800.742.2740). Incorrect assembly may result in risk of electrical shock
or fire.
WARNING: RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS.
Batteries generate explosive gases during normal battery operation. For this
reason, it is of utmost importance that prior to each use of the ProXtra unit you
read this manual and follow the instructions exactly.
To reduce risk of battery explosion, follow these instructions, those published by
the battery manufacturer, and those published by the manufacturer of any
equipment you intend to use in the vicinity of the battery. Review all cautionary
markings on these products and on the engine.
PERSONAL PRECAUTIONS
The ProXtra is designed to be permanently installed in the boat specifically for
the purpose of supplying charging current to the trolling motor batteries while
operating the main boat engine. Other types and uses, including unauthorized
attachments, should be avoided due to possible damage and/or personal injury.
Do not attempt to operate the ProXtra in a battery configuration that utilizes
a series connection between the engine starting battery and the trolling
motor battery or batteries. Severe sparking and/or damage to the ProXtra
may occur and the warranty will be voided. Please contact technical
support for further information (800.742.2740).

Someone should be within range of your voice or close enough to come to your
aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, eyes, or other surfaces.
Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
If battery acid contacts skin or clothing, wash immediately with soap and water.
If acid enters eye, immediately flood eye with running cold water for at least 10
minutes and seek medical attention promptly.
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto the battery, which
might cause a spark or short-circuit the battery or another electrical part, possibly
resulting in an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with a lead-acid battery. A lead-acid battery can produce a short-
circuit current high enough to weld a ring or the like to metal, causing a severe
burn.
Use the ProXtra for charging a LEAD-ACID (lead acid, sealed lead acid, gel cell,
and AGM) battery only. Do not use this system for charging dry-cell batteries
that are commonly used with home appliances. These batteries may burst,
causing personal injury and damage to property.
NEVER charge a frozen battery.
PRODUCT SUMMARY
General Operation
Use the following guidelines in this manual to install your PCS ProXtra system.
Assure that the area around your batteries is properly ventilated.
During normal operation the ProXtra system monitors the starting battery voltage
and will activate once the starting battery voltage rises above a predetermined
voltage. Once this point is reached, charging current from the boat motor
charging system will continue to flow to the additional batteries attached to the
ProXtra system. When the starting battery voltage drops below a predetermined
voltage, the ProXtra system is deactivated and returns to a standby state. Light
Emitting Diodes (LEDs) on the ProXtra case indicate the status of the unit.

INSTALLATION INSTRUCTIONS
Do not make any electrical connections to the main engine battery or additional
batteries until the installation process has been completed.
The ProXtra may be mounted at any angle. For best results, place the ProXtra at
the desired location and mark the screw locations, using the mounting bracket as
a template.
Check for fit and appropriate thickness of the mounting area before drilling starter
holes. Use the four screws that have been provided to install the unit on a flat
surface as high above the water level as possible.
Locate the cable labeled starting battery and securely connect the ring terminal
of the black cable to the negative post of the starting battery. Locate the cabled
labeled trolling motor battery and securely connect them to the trolling motor
battery or batteries as shown. (Red wire to + terminal/Black wire to – terminal.)
Locate the purple wire at the end of the starting battery cable assembly. Using
the supplied quick connector, attach the purple wire to any 12 volt source on the
boat that is disabled when the boat is not in use. The purpose for this connection
is to disable the ProXtra circuitry during times that the battery may be charged by
other means (i.e., AC powered battery charger).

POST-INSTALLATION TESTING
After completing the total installation process for the ProXtra, it is possible to test
the unit for proper operation without having to operate the main engine.
1. Attach a battery charger designed for a 12 volt system to the starting
battery.
2. Turn on the boat electrical system (key switch on).
3. Turn the battery charger on and observe the indicator lights on the ProXtra.
When the voltage of the starting battery reaches a predetermined level,
both indicator lights on the unit should illuminate.
4. Turn the battery charger off and observe the indicator lights on the ProXtra.
As the battery voltage drops to a predetermined level, both indicator lights
should extinguish.
5. If you are unable to accomplish the previous steps for any reason, please
call PCS technical support (800.742.2740) and we will gladly assist you.
CAUTION! Do not attempt to operate the ProXtra in a battery configuration that
utilizes a series connection between the engine starting battery and the trolling
motor battery or batteries. Severe sparking and/or damage to the ProXtra may
occur and the warranty will be voided. Please contact technical support for
further information (800.742.2740).

TROUBLESHOOTING
PROBLEM: No indicator lights are illuminated on the ProXtra during engine
operation.
SOLUTION SEQUENCE:
•Check battery connections for tightness and proper polarity.
•Check in line fuses on Red and Black wires on starting battery cable.
•Call PCS technical support at 800.742.2740.
PROBLEM: Charging Trolling Batteries indicator does not illuminate during
engine operation.
SOLUTION SEQUENCE:
(Note: In order for the ProXtra circuitry to operate, the starting battery voltage
must exceed 13.8 volts. On some small outboard motors, the starting battery
voltage may not reach this point.)
•Check purple wire from starting battery cable assembly. This wire must
be attached to a 12 volt source.
•Check battery connections on all batteries for tightness and proper polarity.
•Call PCS technical support at 800.742.2740.
