How The Trollbridge 24 Charger/Combiner Works
The SmartShore Marine Trollbridge 24™ 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.
Features
• Fully automatic changeover from running to charging
• Simple ve (5) wire installation with included cables
• You can run BOTH motors at the same time
• Manual 12/24-Volt switching available
• Uses the starting battery for a two (2) battery setup
• Built in Combiner isolates starting battery from discharge
• Rated for 12-Volt charging sources up to 150-Amps
• Compatible with most 24-Volt trolling motors (up to 85-Amps)
• Batteries are charged in parallel to equalize their charge for longer life
• Green LED on the Trollbridge 24 shows when 24-Volt output is active
• Compatible with, but eliminates the need for multiple output chargers
• Draws no current when off
• No modication to alternator or 12-Volt wiring required
• Compact, waterproof design and included cables make installation easy
• Efcient electronics design requires no heat sink or cooling fan
• Withstands ambient temperature to over 175° F (80° C)

Operating Modes
TROLLING MODE
The Trollbridge 24 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 24 powers off. While off, the Trollbridge
24 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 twenty (20) seconds.
If the main engine is running, both batteries will receive a charge and both batteries are
available for starting or house loads.
Running both motors (engine and trolling) at the same time does no harm. Because
the batteries are equalized every time the trolling motor is off, unequal charging on the
batteries is not an issue.

Battery Chargers
Multi-Output Battery Charger (Shore Power Charger)
The Trollbridge 24 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 24. 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 both/all positive and both/all negative charger outputs to the start-
ing/cranking battery. This makes your multi-output charger function like a single output
charger and allows the Trollbridge 24 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 24 will
function as normal and charge all batteries equally.

2 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.

3 BATTERY SYSTEM
This conguration uses the starting battery, house battery, and separate trolling battery 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 100 for a lead-acid or AGM type house battery, or a
Combiner 100L for a Lithium type House battery (Combiners sold separately), and the Trollbridge 24 will
combine these with the Trolling battery together to provide 24-Volts to the trolling motor when Trolling
Mode is active.

Trollbridge 24 Installation
WARNING! Don’t Destroy Your Trollbridge 24
Our quality control requires that each Trollbridge 24 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 rated for your motor (typically
60-Amps or less) on the positive (+) connection to the trolling motor. We also recommend the installation
of a 100-Amp in-line fuse on the red wire from the Trollbridge 24 unit to the positive post on the starting
motor battery (+12V) and a 100-Amp in-line fuse on the purple (or white) wire from the Trollbridge 24
unit to the positive post of the trolling motor battery (+24V). 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 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 24 must be heavy enough to carry the trolling motor
and charging currents. We recommend 6- to 10-gauge size wires for this. Longer distances need heavier
wire sizes.
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 24 with damaged wires.
DO NOT operate the Trollbridge 24 if it has been dropped or otherwise damaged in any way.
NOTE: SHORTENING ANY Trollbridge 24 SUPPLIED CABLES WILL VOID THE WARRANTY.
The Trollbridge 24 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 24 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 24 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 24 and could injure you and cause a re.
4. LABEL YOUR BATTERIES
The Trollbridge 24 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 (-) RED – Starting Battery, Positive (+)
GREEN – Trolling Battery, Negative (-) PURPLE / WHITE – Trolling Battery
Positive (+) BLUE – Trolling Motor, Positive (+)
2. CONFIGURE FOR YOUR BATTERY CHEMISTRY
Before connecting your Trollbridge 24, verify that you have the correct
model for your battery chemistry. The Trollbridge 24 is made to work on standard
Lead-Acid, AGM, LIthium, or Wet-Cell batteries.
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.

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 24 wire
color and the connection location (such as red wire terminal to positive post of starting/
cranking battery or green wire terminal to the negative (-) post of the trolling motor battery)
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 24.
5. MOUNTING LOCATION
Mount the Trollbridge 24 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 24 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 15. 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 24 must be heavy enough to carry the trolling motor and charging currents. The Trollbridge 24
terminals are designed to be permanently connected to the batteries.
NOTE: SHORTENING ANY Trollbridge 24 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 rated for your motor
(typically 60-Amps or less) on the positive connection to the trolling motor. We also recommend the
installation of a 100-Amp in-line fuse on the red wire from the Trollbridge 24 unit to the positive post on the
starting motor battery (+12V) and a 100-Amp in-line fuse on the purple (or white) wire from the Trollbridge
24 unit to the positive post of the trolling motor battery (+24V). 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).

Troubleshooting
CHARGE MODE WON’T ACTIVATE
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.
TROLLING MODE (+24V) WON’T ACTIVATE
DOUBLE CHECK YOUR WIRING
If you hear a buzzing sound from the Trollbridge 24 when activating your trolling motor, this indicates that
one (1) of the batteries is not connected.
IS YOUR TROLLING MOTOR ON?
The Trollbridge 24 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 24 and to the
negative (-) terminal of the Starting battery.
MANUAL OVERRIDE SWITCH
If all the wiring is correct and the Trollbridge 24 still fails to switch to Troll 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. To implement manual control, you will need to install an on/off toggle or push button switch
(not provided) rated for 12VDC or higher applications and connect it using smaller gauge wire such as 24
or 22 AWG between the 4-40 threaded post on the Trollbridge 24 and the positive terminal of the starting
cranking battery that has the RED Trollbridge 24 wire on it. When this control switch is turned off, the
Trollbridge 24 will switch back to charging mode (batteries in parallel) after a short delay. When the control
switch is turned on, the Trollbridge 24 will switch to trolling motor mode (batteries in series) to provide 24V
to the trolling motor.

Troubleshooting (Cont’d)
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: +26-Volts or higher
In Charging Mode, the “CHARGING” LED is ON. 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
