In the manufacturing industry, one thing that’s tremendously important is using quality parts when building equipment. If this doesn’t happen, there’s going to be issues with the end product. At Gas Trailer, we go out of our way to ensure that our portable gas trailer models are built with long-lasting, superior parts and materials.
One of those key parts is the battery charging wiring harnesses that we install on our aluminum trailers that have an electrical fuel pump, which we’re going to go in detail about now.
What Is A Battery Charging Wiring Harness
As the name implies, a battery charging wiring harness is the harness made up of the electrical wiring for charging the on-board electric model batteries. The harness features 12V wiring along with a round, 7-pin RV style connector that match the standard configurations you would find on most modern cars, trucks, and other vehicles. We break our harnesses down so that the trailer receives the tow vehicle’s running lights (pin 3), turn signals and break lights (pins 5 and 6), ground (pin 1), and 12V positive power (pin 4).
How The Harness Works
The 12V Battery Power (4) connection is how the battery can be auto-charged. All electric pump model trailers are pre-built with an accessory wire that goes to the battery box compartment. If this accessory wire is connected to the positive terminal on the battery and the towing vehicle provides 12V of power through the same (4) connection pin, then the vehicle’s alternator will auto-charge the battery on the gas trailer while the vehicle is running. The vehicle’s alternator is used as the power source to keep the voltage in your battery full, thereby allowing you to run your 12V electric pump.
*Please note, if the tow vehicle is not equipped to provide 12V power through its #4 pin of the trailer connector, the auto-charging function will not work and a separate battery charger will be needed.
The harnesses used on our aluminum model fuel trailers are extremely well built. Not only do they feature thicker, well-insulated wire, but they’re loomed and wrapped with heat shrink connectors for extra durability.
