Keep Your Dump Trailer Dumping- It Works, It’s Simple And It’s Cheap

Key function of this system:
To disconnect the truck charge wire from the battery when operating dump cycle. This safeguards the truck wiring from excessive amp draw (blowing your auxiliary fuse). If your trailer is equipped with a charging indicator and/or diode (prevents trailer back feed when truck is off) I would install this on the truck side of this jibberish. The test light is not necessary but nice to show your truck is putting out voltage and that the relay is operating properly.
The most cycles I’ve dumped my trailer in a days work is 15. No Problems. If your dumping more than this I would recommend a second battery and/or some heavy battery cable straight back from your vehicle’s batteries(y).

#1. Choose a Test Light of your liking. Incandescents are nice because they show a voltage curve by brightness. LEDs are pretty but they’ll be on or off

#2. Fuse holder and fuse, 3/4 amp for relay coil

#3. Example of a nice relay and harness on Amazon:

Full transcript:
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.


BOSS™ Dump Trailer Charging Testimonial – Purkeys

Purkeys’ BOSS™ Dump Trailer Charging System enables dump trailer batteries to remain at a high state of charge by using energy from the truck to charge batteries, while boosting voltage for fast, efficient charging. This ensures dump trailers are operational when drivers are ready to use them, eliminating the threat of downtime and road calls.
By maintaining a high state of charge in dump trailer batteries, even in cold weather, battery life and reliability is improved. While the BOSS system provides peace of mind in keeping dump trailer batteries charged, it is important to adhere to regular battery maintenance procedures to ensure that batteries are operating properly.

Upgrading the converter / battery charger in my RV to Progressive Dynamics PD4655

Steps I took to upgrade the stock WFCO 8955 converter / battery charger in my RV to a better one: the Progressive Dynamics 4655.

The WFCO is famous for almost never switching into bulk mode (fast charging mode) no matter how low of a charge the batteries have. Because of this limitation, it’s impractical to dry camp – unless one plans on having to run their generator all day and night.

I haven’t gotten the new PD4655 to output 55 amps to the batteries just yet, but it’s already preforming MUCH better than the WFCO. I’m certain that once I upgrade the battery cable gauge from AWG #6 to AWG #3, I’ll get an even faster battery charge – in a matter of a few hours instead of 12+ hours. Even without upgrading the wiring, the PD4655 is already charging the batteries much faster.

NOTE: Tech support gave me instructions for fixing the problem with the green status LED not working. It turns out that the conductors in the 4-pin connector were in connected (at the factory) in the wrong sequence. I’ve posted the simple fix here:
