(TROLLBCOMBINER100)
CHARGE 24-VOLT TROLLING BATTERIES FROM 12 VOLTS
SUMMARY
«;)
July 2010
The Trollbridge12X24® is a 12-volt Combiner100 and
Trollbridge24 all in one package, which allows you to charge
your 24-volt trolling motor battery from the 12-volt alternator
on your main engine, from your trailer hookup, or from any
single or multi-output 12-volt charger without risk of
running down your starting battery. It works automatically by
putting two 12-volt batteries in series when you need to run
the trolling motor, and putting them in parallel for charging.
It only charges the trolling batteries when the main engine
is on.
FEATURES
Fully automatic, no switches or connectors to change
Starting battery will never discharge into trolling motor
Both batteries operate in parallel when not trolling
Automatically switches in series for 24-volt output
Batteries are only charged when the engine is running

DANGER
:
During installation voltages may
be present on unattached cables. Make sure
these
do not short out to boat ground
,
battery positive
,
or
to each other.
15% of Trollbridges are DESTROYED due to
installation errors
.
WARNING
Fuses are not normally used on the trolling battery
positive cables however if you do BOTH must be
fused.
HOW IT WORKS
The Trollbridge12X24
®
connects two 12-volt batteries to
your starting battery to make 24 volts. The two
trolling batteries are in parallel at 12 volts when not trolling.
When the starting battery reaches 13 volts or more the
amber LED comes on and the trolling batteries receive
charge.
The first trolling battery can also be used as a house
battery for other 12-volt loads ..
The second "trolling" or "booster" battery is used only for
the trolling motor and
cannot
be connected to anything
else.
INSTALLATION
We recommend 6-gauge wire for the motor cables and for
extending the supplied cables. Tap cables to terminal before
connecting to check for sparks, which indicate a wiring error.
DO NOT
run multiple cables together in a plastic conduit,
they are rated for 60 amps in free air. In conduit they may
overheat and melt insulation.
OK to cut off terminals to extend cables.
1.
IMPORTANT
Remove any existing jumper from trolling
battery
1 positiveto
battery
2negative.
Sometimes this
jumper connection is inside the trolling motor plug.
2.
Any existing battery charger cables can be left as-is.
3.
Connect starting battery negative to the first trolling
battery negative with a black cable. 10-gauge is OK but
if the run is over 6 feet, use 8- or 6-gauge.
4.
Connect the
BLACK
Trollbridge12X24® ground wire to
the negative of the first trolling battery. Lengthen if
needed.
5.
The
RED
cable is connect to the positive terminal of the
first trolling battery which can also be used as a house
battery.
SHORTENING THIS CABLE WILL VOID THE
WARRANTY

.
Extending is OK
If you want a safety breaker in this circuit it should be
rated at 100 amps maximum. See
WARNING
- - if fused
the
PURPLE
cable must be fused also.
6.
Connect the
GREEN
cable to the second trolling battery
negative terminal.
No other connections should be
made to this negative battery terminal.
SHORTENING THIS CABLE WILL VOID THE
WARRANTY*
.
Extending with 8- or 6-gauge wire is OK.
7.
Connect the
PURPLE
(sometimes WHITE) cable to the
second trolling battery positive terminal. The trolling
motor does
NOT
connect to this terminal.
No other
connections should be made to this positive battery
terminal.
SHORTENING THIS CABLE WILL VOID THE
WARRANTY*
