Important Charger Operation Note:
Once your new ProSport is installed and properly connected to batteries you will be ready to plug it in.
Please note the ProSport has a built-in self test feature that will also analyze all battery connections
and batteries to determine your boats batteries are capable of being charged correctly. The
self test is automatic and will take place everytime the unit is plugged into a 120/230 VAC outlet.
The self test may take up to 2 minutes to complete.
During the self test the red charge mode indicator will be flashing. When completed if everything
is connected properly and the batteries are OK and above 2.0 volts DC then the charger will register
and illuminate the green system check OK indicator followed by a solid (non flashing) red charge
mode LED illuminating indicating all batteries are being charged.
If the charger does not go into the charge mode with a solid (non flashing) red charge mode
indicator and the system check OK indicator is not illuminated with a solid green LED then a
red battery bank fault LED will illuminate identifying the battery(s) that have either a wiring
fault present i.e. poor connection, a blown DC cable fuse, the DC cable is wired in reverse
polarity, battery cable is wired across two batteries in series with a high DC overvoltage of
24V or the battery itself may be under 2.0 volts DC. In any of these cases refer to the
troubleshooting section on page 25 of this manual.

5. Prepare each battery in advance by cleaning each terminal post with a wire brush until a shiny surface is
obtained.
6. Run cables free from sharp objects and hold each in place with cable ties. Coil excess cable, do not cut
or shorten the length of the cables, as in-line fuses are located 4 inches from the end of each positive (red)
cable. In addition, there are fuses in all but one of the negative (black) leads. These fuses protect the charger
and output cables in the event of a wiring short. We recommend the use of wire ties or cable clamps to
provide strain relief for the cables and to reduce the risk of damage to the cables or connections.
7. Connect the DC output cables as illustrated on pages 16-22. Make sure the (black) wires are connected as
illustrated to the negative side of the battery and the (red) wires are connected to the positive side of the battery.
Important Note: Your ProSport charger will not operate properly if it is not connected properly to each
battery. Reminder, The ProSport and each DC jacketed bank cable must be properly connected to
“individual 12V batteries”. Number of DC jacketed bank cables equals the number of batteries that must
be individually connected. Example: a 3 bank ProSport 20 Three Bank charger must be connected to 3
individual 12V batteries, as illustrated on pages 16-22. Simply choose the illustration that has the same
number of charger output bank cables as your ProSport Battery Charger in hand and wire exactly as
shown (choose the illustration that matches your application) for proper charger operation.
8. Make sure all DC connections are correct, tight, and free from corrosion.
9. Locate the AC power cord in an open-air area of your boat at least 21 inches from the charger, batteries,
and fuel fill lines.
10. Connect a heavy duty UL approved extension cord to the battery charger first. After connecting the
extension cord to the charger, proceed to plug the extension cord to a nearby 120/230 VAC
GFCI protected (Ground Fault Circuit Interrupt) outlet. Always remove the extension cord from the
120/230VAC outlet first when charging is completed, followed by unplugging the charger. You are now
connected and charging your batteries. View the LED indicators.
4 Steps to Wire your ProSport Charger Correctly
STEP 1: Simply choose the illustration that has the same number of charger output bank cables as your
ProSport Battery Charger in hand and wire exactly as shown (choose the illustration that matches your
application) for proper charger operation.
STEP 2: Do not remove your batteries series or parallel jumper cables that interconnect batteries to each
other. ProSport Chargers are designed with isolated outputs and series or parallel jumper cables do not have
to be removed.
STEP 3: Your ProSport charger will not operate properly if it is not connected properly to each battery.
Reminder, the ProSport and each DC jacketed bank cable must be properly connected to “individual 12V
batteries”. Number of DC jacketed bank cables equals the number of batteries that must be individually
connected. Example: a three bank ProSport 20 3 Bank must be connected to 3 individual 12V batteries. As
Illustrated on Pages 16-22. Select your battery / trolling motor configuration for the specific wiring illustration
needed for your charger.

STEP 4: Incorrect wiring will result in reverse polarity or high reverse voltage, in the event this happens, the
ProSport Charger has been designed to not fail as a result, however it will cause the charger to “internally
disconnect” and provide “no output” until the (reverse polarity caused by putting the “red” + lead on
a - negative battery terminal) and or the (high reverse DC voltage caused by taking one bank cable and
spreading it across two batteries) is corrected, using the wiring diagrams as shown on pages 16-22. In the
event of a reverse polarity connection or an improper battery connection or if an output is not connected
to a battery the appropriate red battery bank trouble LED will illuminate identifying the battery and wiring
connections where a fault is present. See page 25 for further details.
Installation
When connecting each jacketed battery charger cable, make sure it is connected
to only one 12 VDC battery and observe the polarity and color of all connections:
Red Wire = + (Positive) Battery connection
Black Wire = - (Negative) Battery connection
The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12VDC battery.
Each charger cable must
be connected to 1 battery,
just as shown. Observe
black to (-) and red to (+).
Do this for each battery. cable jacket
