Today on this enclosed trailer were going to install part number 20011 from Hopkins. This is their trailer breakaway kit battery charger. Right now, looking at our trailer the way its hooked up is that it does not have a battery charger. It has a 12 volt power lead coming off the towing vehicle going straight to the battery that will charge the battery, but over time that could overcharge the battery, especially on a long trip. Were going to install our battery charger. The first step is we will go ahead and locate the wiring that comes off the battery charge from the towing vehicle and we will hook that up to the black wire.
Next we will go ahead and take the red wire and we will hook that up to the battery on the trailer, that way the battery will be getting a charge. Now the blue wire coming off the charger will go out to our breakaway switch. You can use a variety of different connections. In this case we will be using wire nuts. Once our connections are made we can take our charger and tuck it in next to the battery.
With that, that will finish it for our install of part number 20011 from Hopkins on this enclosed trailer.
