YANDINA TROLLBRIDGE36 Combiner Charge 36V Trolling Batteries from 12V Installation Guide

The 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.

WARNING
IF TYPICAL EXISTING BATTERY JUMPERS ARE NOT DISCARDED THE TROLLBRIDGE36® WILL SELF DESTRUCT AND VOID THE WARRANTY. Internal automatic switches in the Trollbridge36® will take the place of these jumpers as it switches between series and parallel.

DANGER: During installation voltages may be present on unattached cables. Use supplied terminal covers to protect from sparks

15% of installations are destroyed by connection errors.
Replacements are $75 if installed wrong.

Four Battery System:

Uses the starting battery and three trolling batteries to make 36 volts. The 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. The trolling motor will never use power from the starting battery.

Three Battery System:

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 BLACK and RED cables. The YELLOW cable will go to the same terminal as RED if using the starting battery for trolling.

INSTALLATION

See the appendix for use of circuit breakers and fuses.
The 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 currents.

SHORTENING ANY Trollbridge36® SUPPLIED CABLES WILL VOID THE WARRANTY. Extending with 6 to 10 gauge wire is OK. Cutting off 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 current rating is only for open air In conduit they may overheat.

1. Remove ALL existing battery cables, SEE WARNING.

2. On a 4 battery system with isolatead starting battery, connect the negative of the starting battery to the negative of battery 1.

3. Connect the BLACK Trollbridge36® ground wire to the Negative terminal of battery 1. 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 1. On 3 battery systems this is also the starter motor positive connection.

5. The YELLOW 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 YELLOW cable to the RED terminal.

6. Connect the PURPLE to battery 2 negative.

7. Connect the WHITE cable to battery 2 positive.

8. The GREEN cable goes to battery 3 negative.
   NO OTHER WIRES CONNECT TO THESE TERMINALS

9. Connect the BLUE cable to the trolling battery 3 positive terminal. This is the +36 volt supply to the trolling motor.

TROLLING MOTOR CONNECTION:

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

OPERATING INSTRUCTIONS

DEEP DISCHARGE IS THE BIGGEST BATTERY KILLER. Avoid running below 37-volts as much as possible.

Off

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.

Charging

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 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 Trollbridge36® may cycle on and off to prevent overloading the alternator and preserve the starting battery charge.

Trolling

When charging stops there will be a delay until the battery voltages drop below 13. Before the 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.

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 wire to 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 enter charging mode.
When charging, measure the voltage on the starting battery, the Trollbridge36® 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 wire.
Check the wiring by putting the negative meter lead on the BLACK cable. When the LEDs are off you should measure +12-volts on RED and PURPLE, +24-volts on WHITE and GREEN and +36-volts on BLUE.
If the green LED is on all battery positive terminals should read nearly the same voltage as the starting battery (13.0 to 14.2 depending on state of charge.).

If one of the batteries has failed or the trolling motor is running, the Trollbridge36® will not switch to parallel mode for charging. When charging is terminated the green LED will go off and the output reverts to 36-volts. This happens when the batteries get down below 13-volts. There is a time delay which can be canceled by operating the REMOTE button.

APPENDEX

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 line can be connected to the starting battery to charge all batteries.

Radio Remote Button: If you need to run both motors at the same time or 36-volts is not available soon enough after charging has stopped, momentarily press the remote control button. This will set it in the 36-volt mode. To release 36-volt mode and resume charging, hold the remote button for 10 seconds. Charging will only resume when all parameters are met and the trolling motor is not running.

Circuit breakers and fuses: The 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 terminals could be fitted with disconnect switches and 100-amp slow blow fuses but if the wiring is well protected from accidental damage they are typically omitted.

WARRANTY VOID IF SUPPLIED CABLES ARE MADE SHORTER but OK to cut off and replace terminals.
