Video Transcript for Review of Deka 3/8 Ring Terminal - DW05705-1

Michael: Hi there, I'm Michael with etrailer.com. Today, we're going to take a very quick look at this Deka ring terminal. This ring terminal is going to allow you to easily connect your wires to a stud, so like on a battery or something like that where you need a nice solid connection. This does allow you to crimp the vinyl installation down onto your exposed wire. This is going to have an internal diameter right about 3/8 of an inch. So it's going to be good for your 3/8 inch diameter studs, will fit right up in there.

This is going to work for your 12 and 10 gauge wires, will fit right in there, allow you to crimp down on them and give you that nice secure connection to attach to your stud. That's going to complete our look at the Deka ring terminal. Again, I'm Michael with etrailer.com, thanks for watching.

I have been dealing with etrailer for about five years and have never been disappointed. Products are as described and work well, the web-site is excellent and customer service is fantastic. One instantly gets to talk with efficient well-informed people without any of the usual run-around. The instructional videos, for example mounting of trailer hitches, are extremely good, and prices are competitive.



by:

I just purchased a Ranger Bass boat and the wiring is very old and the lights don't work. I found everything that I needed to completely replace and install new wiring and lights. This is a very good website to find and get exactly what I needed. I would highly recommend that people shop this site for all their trailer wiring needs.

  • Both Turn Signals Flash at The Same Time
    The cause of both turn signal lights flashing together would almost certainly be attributed to a poor ground. There are several grounds you will want to check which include one for each light, the trailer side trailer connector and the vehicle side trailer connector. One of these locations will more than likely contain the problem you are experiencing. It is important to make sure each ground is attached to a bare metal surface. It may be necessary to undo the ground wire and then use some...

  • Installing GCH Truck Bed Cargo Camera # 3460010 on 2018 GMC Sierra 3500
    The third cable you mentioned for the Truck Bed Cargo Camera # 3460010 will indeed plug in between the camera and module cables also included with the kit. The red and black leads are for the camera's power and ground. The module also includes extended leads for power and ground. I have labeled the picture you attached accordingly. The ground leads (black) from the module and camera need to be attached to a bare metal surface using ring terminals like # DW05705-1 and a screw. The...

  • How to Create an Electrical Grounding Plate on DIY Truckbed Camper for Running Lights
    The short answer to your question is, no. You're going to be best served by running your ground wires together and grounding them at a single point on the trailer using a ring terminal like the # DW05705-1 and a junction box like # 38656. Since aluminum not is a great conductor of electricity, that wouldn't be a good choice to create your grounding plate- if you can ground it to steel instead that would be optimal. If you need wiring to run all these grounds together you can use 16 gauge...

  • How To Wire Together Four 12 Volt Batteries To Output 24 Volts
    If your intent is to have 24 volts of output, you can wire 4-12 volt batteries together. In order to connect your 4-12 volt batteries to get 24 volts of output you need some wiring and ring terminals like parts # 10-1-1 and # DW05705-1. You're going to connect your power wire to the positive post on one battery and run a wire that connects that same post to the positive post on the second battery. Then connect the negative posts on both of those batteries to the positive posts on the...

  • Tips for Getting a Large Trailer Wire to Fit into a Small 7-Way
    If you are having a hard time getting the connector wires from your trailer into the replacement 7-way that you have there are a couple things you can try. The first thing I would try would be to twist the end of the exposed wire until it will not twist anymore. This will make the wire as skinny as possible and give it the best chance at fitting in the slots. Or you could use ring terminals like our part # DW05705-1 to attach to the wire, and then attach the ring terminal to the 7-way....

  • Grounding Trailer Lights That are Mounted to Wood Rather than Metal
    If the lights you are using have wires coming out of the back like the Optronics Camping Travel Trailer Stop, Turn, Tail and Back-Up Light, part # RVST56, then you can simply connect an extension wire like part # DW02359-1 from the ground wire on the light to the trailer frame and ground the white wire from your trailer connector to the trailer tongue. If the lights you are using ground through the mounting hardware, then you can simply run a jumper wire from the post on the light that...

  • Using Battery Charger Included With HM39530 Brake Buddy When Negative Battery Cable is Disconnected
    We've got a solution for you. You'll want to use a Deka Quick Disconnect Battery Terminal, part # DW05312. On the terminal end that remains on the battery once disconnected, you'll attach the ground wire for the charger using a # DW05705-1 ring terminal. This leaves the charger grounded once the negative battery terminal is disconnected. I've provided a photo showing where to place the ring terminal.

  • Power To Brake Controller and Trailer Connector on a 2006 Chevy Silverado 2500 Cut Out
    The power for the brake controller and trailer connector on your 2006 Chevrolet Silverado 2500HD is feed from two studs on the power distribution center (PDC) which is located under your hood, in the engine bay. The only thing that I can think of as to why both the power for the brake controller and trailer connector suddenly went out assuming there were no blown fuses is if the ring terminals on these studs somehow came loose. Therefore, you will want to check the flange nuts on both of...

  • Trailer Tail Lights Dim When Brake Pedal Is Depressed
    The most likely cause of the tail lights dimming when the brake pedal is depressed will be attributed to a poor ground. Therefore, in order to fix this issue you will need to either try and clean the ground point or run a separate ground wire from each tail light up to the trailer connector. This should then fix your issue but if it does not then please just let me know and I would be happy to further troubleshoot this issue for you. If you need extra wire to run the separate grounds and...

  • Recommended Trailer Winch Wiring Options for 1994 Ford F-250 XL
    To add a trailer winch to your 1994 Ford F-250 XL, the factory 12V power supply will not be substantial enough for the power draw of your winch. You will need to have a separate trailer battery for that function, but you can charge that trailer battery from your vehicle 7-way when you hardwire it. You will need # 10-1-1 wire along with circuit breaker # 9510 and ring terminal # DW05705-1. This will allow you to get the length of wire needed to connect directly to your vehicle battery,...

  • How To Keep Trailer Battery That Powers Winch Charged While Its Being Towed
    I would be happy to help! If the maintenance charge is enough for your battery, then running the # 10-1-1 from the 12v accessory circuit of your 7-way connector to the positive terminal of your trailer's battery using a ring terminal # DW05705-1. Keep in mind that this will not keep the battery from draining while using a winch or tongue jack, as this circuit does not offer much power. To keep the battery from going dead a better option would be running the Bulldog Winch Rear Wiring...

  • Connecting Electric Trailer Jack Directly to 12V Battery
    To hook up a trailer jack to a 12 volt battery you need to make the connection from the jack's power wire to the positve post on the battery using a ring terminal, like part # DW05705-1. If you don't already have a battery on the trailer you can add one. You'll need to power it by connecting it to the trailer connector's 12 volt power circuit. You can use part # HS381-9000 if you need to add a 7-way on the trailer. You'll also need a 7-way connector on the tow vehicle, which I can help...

    The Optronics 7-Way Connector, # A7WCB, can be used to replace your current connector which has 2-10 gauge wires. When connecting the 10 gauge wires, as well as the other wires, you can use a ring terminal like part # DW05705-1 if you prefer.

  • Connecting a Power Lead From an Electric A-Frame Jack to Trailer Accessory Battery
    If you are using an internally grounded electric jack like the Ultra-Fab Electric A-Frame Jack, part # UF38-944017, you simply run the power lead to the accessory battery on the trailer and connect it to the positive terminal using something like a ring terminal, like part # DW05705-1. You will also want to make sure the negative post of the battery is grounded to the trailer frame so the circuit is complete. This type of jack will only require the power lead wire to be connected as it...

  • Trailer Warning Lights Flash in Vehicles Message Center
    The trailer warning lights flashing in your message center sounds like either a ground issue on the trailer or a corrosion problem between the trailer connectors. I would first start off by disconnecting the trailer connectors and using a bit of electrical spray to clean the pins. Once done, I would also use a bit of dielectric grease like part # 11755 between the two connectors before mating them back together to prevent future problems. Before you move onto the trailer wiring, I also...

  • etrailer Electric Tongue Jack With Footplate Compatibility With a 2005 Artic Fox Travel Trailer
    The Electric Jack w/ Footplate # EJ-3520-WBX will work on your 2005 Artic Fox travel trailer as long as you have a 2-1/4" center hole in the A-frame jack mount location. It is important to check this as some older campers have a smaller diameter center hole. There is only one electrical wire for the jack that will need connected to the battery on your Artic Fox. The ground connection is achieved through the mounting hardware that is included. A 3/8" Ring Terminal # DW05705-1 will make...

  • Will My Camper Drain My Tow Vehicle Battery
    Over the course of a few hours this should not be a concern but beyond that definitely. One option is just unplugging the trailer from your tow vehicle. You can also install a battery isolation solenoid onto your tow vehicle like the Battery Isolation Solenoid Item # PK5231201. This switch installs inline with the 12 volt auxiliary circuit so it turns off when your truck is turned off. The 12V feed remains active when your vehicle is running only. This helps prevent your tow vehicle...

  • How To Run a 12 Volt Power Wire for the 7-Way on a 2008 Chevrolet Silverado
    The 12 volt power wire that goes from the power distribution center to your 7-way trailer connector should be a red/black wire but so long as you are splicing into the one that is ran to to the correct terminal (see photo) then color will not matter. Once you have this wire you will need to cut it in two, splice the end from the connector onto part # 10-1-1 (per foot) with part # 224775 and then run this wire up to the power distribution center stud with part # 185917 and part # DW05705-1.

    The Optronics LED RV Interior Double Dome Light with Switch - 815 Lumens - White Housing - Clear Lens # RVILL34 are designed to be wired into your RV or trailer's power distribution box. If you're using this to replace an existing light, you'll just connect the black wire to power and the white to ground since the connection to the power distribution box is already made. If you're installing this completely new without any existing wiring, that would need to be run to the power distribution...

  • Trailer Tail Lights Pulsate When Running Lights Are Activated
    The issue you are having with your lights pulsating is because of a bad ground. This usually happens when multiple signals are applied at the same time because the increased power draw then becomes too much for the ground to handle. In order to fix this issue I recommend using a junction box like part # 38656. Once you have this installed you can then run the grounds for all of your lights and the trailer connector to the ground terminal inside the junction box, then to a single point on...

Once you have this installed you can then run the grounds for all of your lights and the trailer connector to the ground terminal inside the junction box, then to a single point on the tongue with 10 gauge wire part # 10-1-1, a ring terminal part # DW05705-1, and a self-tapping screw part #...

  • Troubleshooting a Tekonska Sentinel Controller
    According to my information the Sentinel Brake Controller does have to be connected to a trailer to operate. There will be a green light that comes on when the controller identifies that the trailer is connected to the truck. After you have this then you will be able to set the gain. If you continue to have no power to your controller after you connect the two, then it sounds like you are missing the 12 volt power wire being routed from your brake controller to the battery used in combo...

  • Troubleshooting Ground Circuit on Trailer
    Good job in testing using a different trailer! You've effectively eliminated the tow vehicle as being the problem. You are absolutely on the right track in suspecting a ground problem to be the cause of the issues you're having. The fact that none of the lighting functions are working would tend to rule out a loose connection or broken wire. A trailer connector will typically ground to the trailer tongue. From the trailer connector, trace the white wire to where it attaches to the trailer...

  • How to Ground Optronics Trailer Light ST60RB When Mounting to Wooden Surface
    In order to make a good ground connection with the Optronics Jeep Style Universal Trailer Stop, Turn, and Tail Light # ST60RB you can install a ring terminal and separate ground wire on one of the mounting posts. You can use ring terminal # DW05705-1 and a length of wire like # 10-1-1 to connect to a metal portion of the trailer frame. Any of the three mounting studs can serve as your ground.
