How The Trollbridge 12x24 Charger/Combiner Works
The SmartShore Marine Trollbridge 12x24™ Charger/Combiner allows you to charge your 24-Volt trolling
motor batteries from the 12-Volt alternator on your outboard. It will do the same with any single output
12-Volt charger, or even your trailer hookup. It works automatically by switching the battery connections
from 12-Volts (parallel) to charge, to 24-Volts (series) when you need to run the trolling motor. It only
charges the trolling batteries when the main engine is running.

Operating Modes
TROLLING MODE
The Trollbridge 12x24 automatically switches from Charging to Trolling Mode when you
turn on the trolling motor. Trolling Mode activates quickly when the trolling motor is
detected, and the GREEN LED will turn on to indicate 24-Volts is going to the trolling
motor.
When the trolling motor is active the Trollbridge 12x24 powers off. While off, the
Trollbridge 12x24 draws no power, so it can always remain connected to the batteries.
CHARGE MODE
Charge Mode will activate when the trolling motor is off for about thirty (30) seconds.
If the main engine is running and the starting battery is over 13-Volts, the amber LED will
turn on and all batteries will receive a charge from the engine’s alternator.
The rst trolling battery can also be used as a house battery for other 12-Volt loads.
The second trolling battery is used only for the trolling motor and CANNOT be
connected to other electronic devices.
Running both motors (engine and trolling) at the same time does no harm although only
one (1) battery will get charged. Because the batteries are equalized every time the
trolling motor is off, unequal charging on the batteries is not an issue.
12/24-Volt motors will work with the Trollbridge 12x24 as well but do require
specic wiring instructions outlined at the end of the installation instructions (Step 18
on Page 12). These trolling motors will use both batteries in parallel for 12-Volts and in
series for 24-Volt operation.

Battery Chargers
Multi-Output Battery Charger (Shore Power Charger)
The Trollbridge 12x24 is compatible with multi-output chargers, but they are not
necessary. If you already have a multi-output charger you can congure it two (2) ways;
separate from, or through the Trollbridge 12x24. Your multi-output battery charger can
be left in place in the normal conguration with each charger bank connected to an
individual battery. Do NOT run your outboard engine and the external multi-output
battery charger at the same time. Damage could occur. An alternative method to use
your multi-output battery charger is to connect all positive and all negative charger
outputs to the battery with the YELLOW wire on it. This makes your multi-output charger
function like a single output charger and allows the Trollbridge 12x24 to equalize the
charge of all batteries which can extend their life.
Single Output Battery Charger (Shore Power Charger)
When a single output charger is connected to the starting battery, the Trollbridge 12x24
will function as normal and charge all batteries equally.

3 BATTERY SYSTEM
This conguration uses a large 12-Volt battery to start the engine and combine with a 12-Volt trolling
batteries to combine for 24-Volts. The starting battery typically has a much larger capacity than the trolling
battery so you can still start the engine when the trolling battery is low.
NOTE: For the 3-battery system, you will omit the starting battery and connect the main engine to
the battery with BLACK and RED cables. The YELLOW cable will go to the same terminal as RED
if using the starting battery for trolling.

4 BATTERY SYSTEM
This conguration uses the starting battery, house battery, and separate trolling batteries to make 24-Volts.
The trolling motor should be dedicated and NOTHING else should connect to it. For maximum life, the
batteries should be matched as closely as possible for age, capacity, and chemistry. The trolling motor will
never use power from the starting battery. The Starting battery and House battery will connect in series
together through the additional Combiner (sold separately), and the Trollbridge 12x24 will combine these
with the Trolling battery together to provide 24-Volts to the trolling motor when Trolling Mode is active.

Trollbridge 12x24 Installation
WARNING! Don’t Destroy Your Trollbridge 12x24
Our quality control requires that each Trollbridge 12x24 is thoroughly tested and passes various tests
multiple times prior to shipment. If you install it improperly you can destroy it. The cost for a replacement
after improper installation can be up to half the original purchase price plus shipping to replace. To avoid the
risk of melted cables or re you SHOULD install a circuit breaker, current rated for your trolling motor, on
the positive connection to the trolling motor (Blue wire). We also recommend the installation of a 100-Amp
in-line fuse on the Purple (or White) wire from the Trollbridge 12x24 unit to the positive post on each of the
trolling motor batteries (+12V). An additional circuit breaker, rated at 100-Amps maximum, installed on the
RED wire going to the Starting battery is recommended as well. These fuses and circuit breakers will help to
protect against wiring errors during the installation. The recommended fuse holders and replacement fuses
are available to purchase in the Accessories section of our website (SmartShoreMarine.com).
Fuses And Circuit Breakers
The positive feed to the trolling motor should always have a circuit breaker, 60-Amp rating is typical.
For ultimate protection and ABYC compliance, the yellow, red, and purple/white wires to the battery
positive terminals could be tted with disconnect switches and 100-Amp slow blow fuses but if the wiring
is well protected from accidental damage they are typically omitted.
Wiring
The following connections do not have to be made right on the battery terminals. Any wire or cable
extensions between the battery and the Trollbridge 12x24 must be heavy enough to carry the trolling
motor and charging currents. We recommend 6- to 10-gauge wires, or larger for longer distances.
DO NOT bundle cables in plastic conduit, their current rating is only for open air. In conduit they
may overheat.
DO NOT operate the Trollbridge 12x24 with damaged wires.
DO NOT operate the Trollbridge 12x24 if it has been dropped or otherwise damaged in any way.
NOTE: SHORTENING ANY Trollbridge 12x24 SUPPLIED CABLES WILL VOID THE WARRANTY.
The Trollbridge 12x24 connects the batteries together in parallel (12V) when in Charge Mode.
When multiple batteries are connected in parallel there can be a very high current owing from
the one at a higher voltage to the one at a lower state of charge. The length and size of the leads
supplied provide a resistance to high currents which protects the Trollbridge 12x24 from damage when
the batteries are charging. Extending the wires with 6- to 10-gauge wire is OK. Cutting off existing
terminals to make extensions is OK. Damage caused to the Trollbridge 12x24 by shortening the wires is
not covered under warranty.

Email: [e-mail]
3. REMOVE ALL EXISTING CABLES FROM THE BATTERIES
If you have jumpers in place on your batteries, you must remove these rst.
Leaving the serial + to - jumpers in place it will INSTANTLY destroy the
Trollbridge 12x24 and could injure you and cause a re.
4. LABEL YOUR BATTERIES
The Trollbridge 12x24 output wires are color coded and must be connected to
specic battery terminals in your system for the unit to function properly. Use the
supplied stickers to label the battery terminals BEFORE you start making connections.
Have someone (friend, wife, etc.) check them BEFORE proceeding.
BLACK – Starting Battery, Negative (-) YELLOW – Starting Battery, Positive (+)
BLACK – Trolling Battery 1, Negative (-) RED – Trolling Battery 1, Positive (+)
GREEN – Trolling Battery 2, Negative (-) BLUE – Trolling Motor, Positive (+)
PURPLE/WHITE – Trolling Battery 2, Positive (+)
CLEAN BATTERY TERMINALS BEFORE CHARGING BATTERIES
Lead Acid – After the battery has been charged, ll each battery to the appropriate
level with distilled water. Do not add water to a discharged battery or it may result in
acid leaking which could cause injury or damage to your boat.
Check the battery uid level and terminals for corrosion every thirty (30) days.
2. CONFIGURE FOR YOUR BATTERY CHEMISTRY
Before connecting your Trollbridge 12x24, verify that you have the correct
model for your battery chemistry. The standard Trollbridge 12x24 is made to work
on standard, Lead-Acid, AGM, or Wet-Cell batteries. For Lithium batteries you will
need the Trollbridge 12x24 for Lithium (12x24L), which is an alternate part number.

6. INSULATE YOUR TERMINALS
During installation, use the provided terminal booties to insulate the wire terminals crimped
to the end of each wire. Unconnected cables will have battery voltage coming from cables
that have already been connected. If these short out to anything or to each other,
you can melt wires, blow fuses, damage equipment, or cause a re.
7. VERIFY BEFORE COMPLETING THE INSTALLATION
Have the second person who is assisting with the installation verify the Trollbridge 12x24
wire color and the connection location before making the ring terminal to battery post and
completing the connection for each wire. Follow the suggestions under SAFEGUARDS
on Page 6 of this manual as they are there to protect you, your boat’s equipment,
and your new Trollbridge 12x24.
5. MOUNTING LOCATION
Mount the Trollbridge 12x24 such that you can see the green Charging LED. This will
need to be in an area that is away from a direct heat source, vibration, gas vapors, battery
gases, and above the boat waterline. The battery compartment will typically meet these
requirements. Use bolts/nuts/washers to securely mount the Trollbridge 12x24 in order to
withstand the pounding boats regularly endure on rough waters.
Important Information About The Wiring
See Fuses and Circuit Breakers section on pages 7 or 17. The following connections do not have
to be made right on the battery terminals but any wire or cable extensions between the battery and the
Trollbridge 12x24 must be heavy enough to carry the trolling motor and charging currents. The Trollbridge
12x24 terminals are designed to be permanently connected to the batteries.
NOTE: SHORTENING ANY Trollbridge 12x24 SUPPLIED CABLES WILL VOID THE WARRANTY.
Extending with 6- to 10-gauge wire is OK. Cutting off existing terminals to make extensions is OK.
DO NOT bundle cables in plastic conduit, their current rating is only for open air. In conduit they
may overheat.
To avoid the risk of melted cables or re you SHOULD install a circuit breaker, current rated for your
trolling motor, on the positive connection to the trolling motor (Blue wire). We also recommend the
installation of a 100 Amp in-line fuse on the Purple (or White) wire from the Trollbridge 12x24 unit to
the positive post on each of the trolling motor batteries (+12V). An additional circuit breaker, rated at
100-Amps maximum, installed on the RED wire going to the Starting battery is recommended as well.
These fuses and circuit breakers will help to protect against wiring errors during the installation. The
recommended fuse holders and replacement fuses are available to purchase in the Accessories section
of our website (SmartShoreMarine.com).

CHARGE MODE WON’T ACTIVATE
ARE THE CHARGING MODE CONDITIONS MET?
The Trollbridge 12x24 does not immediately switch from Trolling Mode into Charging Mode. There are
two (2) criteria that must be met to switch back to Charge Mode. When a charging source is detected,
the Starting battery must reach over 13-Volts for thirty (30) seconds. The total voltage of both (2) trolling
batteries must also measure at least 20-Volts. Once these conditions are met, Charging Mode will be
activated, and the green “CHARGING” LED will illuminate. These safety measures are in place to protect
your starting battery and alternator from any bad batteries or wiring shorts.
DO YOU HAVE A BAD BATTERY?
The amount of charging available is limited by the alternator output and how long it runs. Older outboard
alternators often have minimal output so running time for the trolling motor will be governed by the running
time of the main engine and the battery capacity.
MANUAL OVERRIDE SWITCH FOR CHARGING MODE
Many trolling motors draw current even when turned off, and this current draw can prevent the Trollbridge
12x24 from automatically switching to CHARGE Mode. A 60-Amp circuit breaker with an on/off switch is
recommended on the power supply line to the trolling motor. The breaker should be switched off or the
motor should be unplugged when not in use.

Troubleshooting (Cont’d)
TROLLING MODE (+24V) WON’T ACTIVATE
DOUBLE CHECK YOUR WIRING
If you hear a buzzing sound from the Trollbridge 12x24 when activating your trolling motor, this indicates
that one (1) of the batteries is not connected correctly.
IS YOUR TROLLING MOTOR ON?
The Trollbridge 12x24 automatically switches when it detects the load from the Trolling motor.
Double check that the Trolling motor is on and connected properly to the BLUE wire from the Trollbridge
12x24 and to the negative (-) terminal of the Starting battery.
MANUAL OVERRIDE SWITCH FOR TROLLING MODE
If all the wiring is correct and the Trollbridge 12x24 still fails to switch to Trolling Mode (24-Volts) when you
turn on your trolling motor this may indicate that the trolling motor electronics won’t operate while in the 12-Volt
mode. In this case, you will need to install a MANUAL CONTROL switch (not provided) that connects
the short, light gauge YELLOW wire to the 12-Volt battery terminal that has the RED Trollbridge 12x24
cable on it. When the switch is turned ON this will activate Trolling Mode, otherwise Charge Mode will be
active and only 12-Volts will be available to the Trolling motor. There will be a slight delay switching back
to Charge Mode after turning the switch OFF. Light gauge wire is OK for the switch.

WHAT IS THE NORMAL BATTERY VOLTAGE MEASURMENTS?
You can check your battery voltages with a volt meter.
In Trolling Mode, the GREEN LED is ON. Check the wiring by putting the negative (-) meter lead on the
BLACK cable connected to the Starting battery. You should measure +12-Volts on RED, +24-Volts on
PURPLE (or WHITE).
LEAD-ACID – AGM – WET CELL BATTERIES
Starting Battery: RED-to-Black: +12-Volts or higher
Trolling Motor Battery: PURPLE (OR WHITE)-to-Black: +24-Volts or higher
LITHIUM BATTERIES
Starting Battery: Use Lead-Acid, AGM, or Wet-Cell batteries instead
of Lithium batteries for the starting/cranking battery
Trolling Motor Battery: PURPLE (OR WHITE)-to-Black: +13.4-Volts or higher
In Charging Mode, the “CHARGING” LED is OFF. Check the wiring by putting the negative (-) meter lead
on the BLACK cable. All battery positive (+) terminals should read nearly the same voltage as the starting
battery (13.0 to 14.2 depending on state of charge.).
For Lead-Acid Batteries: +12.8-Volts or higher
For Lithium Batteries: +13.8-Volts or higher
