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.

SEE WARNING.
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 BLACK
BLACK Trollbridge36® ground wire to
the Negative terminal of battery 11. This terminal also
connects to the negative of the starting battery and the
negative side of the trolling motor.
4. The RED

cable is connected to the positive terminal
of battery 11. On 3 battery systems this is also the starter

cable is the incoming charging line and
will be connected to the positive of the starting battery.
When extending use no heavier than 10 gauge up to 10
feet, 8 gauge over 10 feet. On a 3 battery system connect

9. Connect the BLUE

cable to the trolling battery 3 pos-
itive terminal. This is the +36 volt supply to the trolling
motor
The Trollbridge36® draws no power when not charging
left connected to the batteries at all times. When “off’
there will be 36-volts available to the trolling motor.
OPERATING INSTRUCTIONS:
TROUBLESHOOTING:
Trolling motor must be off to permit charging.
A volt meter can help diagnose problems. First check the
voltage across each pair of battery terminals.
Measure the output voltage (BLACK
BLACK wire to BLUE
BLUE
). 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 NOT
NOT enter charging
mode.
When charging, measure the voltage on the starting
battery, the Trollbridge36® green “CHARGING” LED
green “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 BLUE
BLUE
wire.
Check the wiring by putting the negative meter lead on
the BLACK
BLACK cable. When the LEDs are off you should

If the green LED
green 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.).
The 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.
The negative side of the trolling motor connects to the
negative terminal of battery 1 as stated above. 6-gauge
wire is recommended

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 first
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 LED
GREEN 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 off 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 LED
LED
goes off
and 36-volts is available for trolling. Press the REMOTE
button if you need 36-volts immediately. This will disable
charging until the charging source (YELLOW

) rests
below 13-volts.
