Below is how the PowerHouse Systems should be wired. Follow the diagrams and use proper wire and size to run the system. If you are extending the output leads of the run & guns you have to use 10awg. Input wires should never be extended but close to 12v cranking battery to provide good voltage to chargers. Failure to do as pictured can cause damage to the system and void all warranties. Damage that occurs, due to improper installation will not be the responsibility of PHL. Be sure to scroll down to see what system you need information on. We will show just the 36v Battery in trolling diagrams but if you use a 24v battery it will be the same procedure and wiring locations. Also cranking battery type does not affect wiring. Same wiring goes to 12v or 16v run and guns as pictured below. Just if you are running 12v or 16v units only you can only have a max of 20 amps charging the 12v starting battery.
Read First Very Important!!!
Models:
DC2DC12, DC2DC16,DC2DC24,DC2DC36 are programmed to be used on only lead acid, gel or agm cranking batteries only. Cannot be used with Lithium cranking batteries.
DC2DC12-L, DC2DC16-L, DC2DC24-L, DC2DC36-L are programmed for use with Lithium cranking batteries.
How to setup DC Chargers in your boat:
Warning: Wiring in reverse polarity will damage the unit and void the warranty so make sure to follow label instructions, and instructions below. Pull fuse out of white wire and open circuit breaker before installing.
-
Wire Red input wire to cranking battery positive (note: use circuit breaker between the run and gun charger and the battery, to be able to turn off the charger.)
-
Use 1 circuit breaker per run and gun charger
-
Wire Black input wire to negative post on cranking battery
-
Wire White output wire to the battery you want to charge on the positive post. Make sure you have removed the fuse before making connections.
-
Wire Black output wire to battery ground.
-
Slight ark is normal when hooking up wires or installing fuse.
Note if you are using a run and gun for a 24v or 36v series setup, hook positive and negative on the same post as your trolling motor is attached. (Ex: 3 12volt batteries)
How to setup your system so it works the best on and off the water:
Setting up 12v or 16v Run & Gun by itself: You need to have a minimum of 10 amps charging the cranking battery with no more than 20 amps to operate the run and gun charger properly.
Setting up 24v, 36v with or without a second run & gun system: Use extra leads from charger to hook to the cranking battery to provide 30 amps of charge current to your cranking battery.
Wiring on DC Charger can be shortened to improve efficiency, and a 20-amp fuse holder must be used on output (white) wire when installed.
Whatever charger your boat came with will be able to be used for running the dc chargers. When taking out 12v batteries and replacing them with 24v or 36v Lithium batteries, You will have extra charging leads that will no longer be needed to charge the trolling motor batteries. Use these leads to get the proper amount of amperage to the cranking battery to charge both the cranking and turn on the DC chargers to charge the batteries they are hooked to. Remember 24V & 36V require 30 amps of charge current at starting battery.
WE ALSO OFFER A 12V 35 AMP WATERPROOF CHARGER PROGRAMMED TO WORK WITH THE RUN AND GUN SYSTEM.
*Note: If you have to extend the wiring to get to both batteries, then you will have to do that from the white wire on the output side. Always try to make Red and Black input wires as short as possible so units run cooler, and more efficient.

Note: If you are charging with an additional 2-Bank or 3-Bank AC charger off the water to charge your lithium batteries directly, be aware that you must turn off the run & gun units before plugging in AC charger. Turn breakers back on when you are on the water only!
