YANDINA Trollbridge36 User manual

e Trollbridge36® Combiner allows you to charge
your 36 volt trolling motor battery from the 12-volt
alternator on your main engine, from your trailer
hookup or from any single output 12-volt charger. It
works automatically by switching the 12 volt batteries
in series when you need to run the trolling motor and
in parallel for charging.

Uses the starting battery and three trolling batteries to
make 36 volts. e three batteries should be dedicated to
the 36 volt motor and NOTHING else should connect
to them. For maximum life, trolling batteries should be
matched as close as possible for chemistry, capacity and
age. e trolling motor will never use power from the
starting battery.
With three batteries, trolling battery #1 is used as a
starting battery and 12-volt instruments, etc. It should
be made much larger than the other two so you can still
start the engine when batteries 2 & 3 are low. Batteries
2 and 3 should be matched for chemistry, capacity and
age for maximum life. You will omit the starting battery
and connect the main engine to the battery with BLACKBLACK
and REDRED cables. e YELLOWYELLOW cable will go to the same
terminal as REDRED if using the starting battery for trolling.

INSTALLATION:
See the appendix for use of circuit breakers and fuses.
e following connections do not have to be made right
on the battery terminals but any wire or cable extensions
between the battery and theTrollbridge36® must be heavy
enough to carry the trolling motor and charging cur-
rents.

to 10 gauge wire is OK. Cutting o existing terminals to
make extensions is OK.

Stick the supplied color coded stickers to the batteries
beside terminals. Wire color should match sticker.
DO NOT bundle cables in plastic conduit, their cur-
rent rating is only for open air In conduit they may
overheat.

2. On a 4 battery system with isolatead starting battery,
connect the negative of the starting battery to the nega-
tive of battery 11.
3. Connect the BLACKBLACK Trollbridge36® ground wire to
the Negative terminal of battery 11. is terminal also
connects to the negative of the starting battery and the
negative side of the trolling motor.

When extending use no heavier than 10 gauge up to 10
feet, 8 gauge over 10 feet. On a 3 battery system connect
YELLOWYELLOW cable to the REDRED terminal.
6. Connect the PURPLEPURPLE to battery 2 negative.
7. Connect the WHITEWHITE cable to battery 2 positive.

there will be 36-volts available to the trolling motor.
OPERATING INSTRUCTIONS:
TROUBLESHOOTING:
Trolling motor must be o to permit charging.
A volt meter can help diagnose problems. First check the
voltage across each pair of battery terminals.
Measure the output voltage (BLACKBLACK wire to BLUEBLUE). If
it is less than about 30-volts you have a bad battery or a
wiring problem and to protect the starting battery and
alternator the Trollbridge36® will NOTNOT enter charging
mode.
When charging, measure the voltage on the starting
battery, the Trollbridge36® green “CHARGING” LEDgreen “CHARGING” LED will
not come on until the battery gets over 13-volts for 30
seconds and there is at least 30-volts on the BLUEBLUE wire.
Check the wiring by putting the negative meter lead on
the BLACKBLACK cable. When the LEDs are o you should
measure +12-volts on REDRED and PURPLEPURPLE, +24-volts on
WHITEWHITE and GREENGREEN and +36-volts on BLUEBLUE.
If the green LEDgreen LED is on all battery positive terminals
should read nearly the same voltage as the starting bat-
tery (13.0 to 14.2 depending on state of charge.).
e positive terminal of battery 3 will connect to the
trolling motor positive supply. 6-gauge wire is normal.
A 50-amp circuit breaker is recommended in this motor
connection for protection against shorts, motor failure
and as a safety disconnect.
e negative side of the trolling motor connects to the
negative terminal of battery 1 as stated above. 6-gauge
wire is recommended
DEEP DISCHARGE IS THE BIGGEST BATTERYDEEP DISCHARGE IS THE BIGGEST BATTERY
KILLER.KILLER. Avoid running below 37-volts as much as
possible.
1. Off
When you start the main engine, or apply any charging
source to the starting battery, the Trollbridge36® will rst
wait for the starting battery to get some charge (13-volts)
then automatically put the trolling batteries in parallel
and deliver charge unless the trolling motor is running
While charging the GREEN CHARGING LEDGREEN CHARGING LED is on and
only 12-volts will be available to the trolling motor so
it will not run. If the trolling batteries are low the Troll-
bridge36® may cycle on and o to prevent overloading
the alternator and preserve the starting battery charge.
2. Charging
When charging stops there will be a delay until the
battery voltages drop below 13. Before the LEDLED goes o
and 36-volts is available for trolling. Press the REMOTE
button if you need 36-volts immediately. is will disable
charging until the charging source (YELLOWYELLOW) rests
below 13-volts.
3. Trolling

If one of the batteries has failed or the trolling motor
is running, the Trollbridge36® will not switch to par-
allel mode for charging.
When charging is terminated the green LEDgreen LED will go
o and the output reverts to 36-volts. is happens
when the batteries get down below 13-volts. ere is
a time delay which can be canceled by operating the
REMOTE button.
§ APPENDEX:
Shore power charger:Shore power charger: If your boat already has a multi output
shore power charger it is compatible with the Trollbridge36
however it does not make use of the equalizing feature of
charging in parallel, which extends battery life. Preferably, all 3
positive and all 3 negative charger outputs should be connected
to the battery that has the yellow wire on it, making it into a
single output charger ..
A truck charging lineA truck charging line can be connected to the starting battery
to charge all batteries.
Radio Remote Button:Radio Remote Button: If you need to run both motors at
the same time or 36-volts is not available soon enough aer
charging has stopped, momentarily press the remote control
button. is will setset it in the 36-volt mode. To releaserelease 36-volt
mode and resume charging, hold the remote button for 10 sec-
onds. Charging will only resume when all parameters are met
and the trolling motor is not running.
Circuit breakers and fuses:Circuit breakers and fuses: e positive feed to the trolling
motor should always have a circuit breaker, 50-amp rating is
typical. For ultimate protection and ABYC compliance, the
Red, White, Blue and yellow wires to the battery positive termi-
nals 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.
