  • Solenoid Recommendation To Prevent Trailer 12 Volt Acc Circuit From Being Active When Key is Off
    We have just what you need. To prevent the vehicle battery from being inadvertently discharged, you can make sure the trailer is unplugged when the vehicle is turned off or you can install a battery isolating solenoid like part # PK5231201. The solenoid would be wired according to the photo I edited for you. When the center pin of the isolator is wired to an ignition powered power source (a circuit that only has power when the ignition switch is turned on), the power feed will only be...

  • How To Prevent Tow Vehicle Battery From Draining Trailer Battery
    As you mentioned, this is normally the accessory battery draining the starting battery (tow vehicle) and most of our products like the Battery Isolation Solenoid, Item # PK5231201, are focused on preventing this situation. It is possible to set this up in reverse but we do not have much experience with it or customer feedback about it. The best solution for preventing your tow vehicle from draining your trailer battery is to have the same type of batteries. In a multi-battery situation,...

  • Are Two Isolation Solenoids Needed for Vehicle with 2 Batteries
    If you are looking to use the isolation solenoid # PK5231201 to activate the 12 volt circuit of your 7-way you would only need one of these as there is only one wire that feeds that circuit on your truck.

  • Which Terminal On a Trailer Connector is Used to Maintain a Charge on the Trailer Battery
    If you have a 6-Way connector, the center pin is the 12 volt power and is usually the pin that would be used for charging a trailer battery. If you have a 7-Way connector, the #4 terminal at the 1 oclock position is the 12 volt power terminal that would be used for charging. I am including a link to a FAQ page on wiring that will show the connectors and the functions of each terminal. When your trailer battery is connected to either of these terminals it will allow you to maintain a charge...

  • Solution for LED Taillights that Stay Partially Illuminated When Circuit is Off
    LED lights can partially illuminate with even the tiniest amount of amperage. What you described isn't super common but we hear about it pretty frequently. What you can use though is the isolation solenoid part # PK5231201 which you'd wire in line with the circuit that stays active and then run the center pin to the same circuit on your Dodge. This allows the circuit to be totally dead when not in use.

  • Battery Isolation Solenoid Recommendation for 2014 Volvo XC90
    Sounds like you are looking for a way to prevent your trailer battery from draining your Volvo battery when the engine isn't running. For that we have the solenoid part # PK5231201. You'd need to install this inline with the 12 volt accessory circuit of your trailer wiring. The center pin gets wired to a circuit that only sees voltage when the vehicle is on and you'd be set. The circuit would prevent the battery from being able to drain the other.

    You can install a battery isolating solenoid like part # PK5231201. The solenoid would be wired according to the photo I edited for you. When the center pin of the isolator is wired to an ignition powered power source (a circuit that only has power when the ignition switch is turned on), the power feed will only be active when the ignition is turned on. If wired correctly, the solenoid will automatically power the circuit up when the ignition is switched on. This is not a vehicle specific...

  • Trailer Brakes Lock Up When Connected to Truck Draining Trucks Battery
    Leaving your trailer connected to your truck overnight will definitely drain the truck's battery. The way to prevent this is to install a battery isolation solenoid # PK5231201 on the truck. The volt circuit on your trailer is a constant circuit so it will always provide power through the 7-way. What do you mean you unhooked the trailer breakaway battery? Did you pull the pin? If you pulled the pin and provide power to the trailer the brakes will lock up. Normally it would charge...

  • Does Battery Isolation Solenoid Draw Amperage
    The Battery Isolation Solenoid Item # PK5231201 that you referenced does not actually draw any amperage worth noting when used. To activate it only take a few milliamps and it does not rob amperage that runs through it on the power pins so you'd be fine using it with a 20 amp circuit.

  • How to Get a Higher Rated Reverse Light Circuit on a Vehicle with LED Reverse Light
    I have a solution for you, but a reverse light circuit setup for an LED would most likely be too low rated amperage wise for what you are trying to do so that is why you are experiencing the problem you have. You are going to need to get an isolation solenoid like part # PK5231201. You would need to run the reverse light circuit of your vehicle to the center post of this and then run a wire from the vehicle battery to one side of the outside pins and then the other side will be a reverse...

  • Installing A Battery Isolator On The Trailer Side Of The Wiring Connection
    I'm happy to help with that isolator and wiring. I checked your invoice and see you went with the Battery Isolation Solenoid # PK5231201. This is a good choice and will need to be mounted to the frame because it uses the mounting holes for ground. Make sure you have a clean area with a metal to metal connection for that mount. From your 7-way, you will run the 12V power wire to the left terminal when facing the 3 pins, the 12V accesory terminal in the middle will go to your running...

  • How to Allow 12 Volt Accessory Circuit of 7-Way to Only Come On When Key is On
    Sounds like you are talking about the 12 volt accessory circuit of a 7-way trailer connector. For some vehicles with factory 7-ways the circuit is only active when the key is on. Most however are on all the time. If the 7-way was hardwired to the vehicle then it will be on all the time unless an isolation solenoid was installed like part # PK5231201. Basically this gets wired inline with the circuit and the center pin, when wired to a power source that is only active when the key is on,...

  • How To Charge Auxiliary Battery On Trailer Only When 2018 Audi Q7 Ignition Is On
    Based on your information, I believe your best option is to add a solenoid like the Battery Isolation Solenoid, Item # PK5231201. This solenoid will shut off the 12-volt feed from your vehicle battery to the 12-volt accessories/auxiliary battery on your trailer when the ignition is turned off. This auxiliary power wire will connect to the 12-volt power pin on a 7-Way connector (see attached picture). I am also attaching a help article and video for you to check out.

    Sounds like you are talking about the picture of the Battery Isolation Solenoid # PK5231201 which I attached. The blue side of the solenoid is to be ran to the 12 volt accessory circuit of your 7-way which is the 1:00 pin.

  • How Does Isolation Solenoid Wire to Activate 12 Volt Power Circuit Only When Key is On
    What you need is the isolation solenoid part # PK5231201. It is pretty easy to wire up too. Basically the outside posts get wired inline with your 12 volt power circuit feeding your 7-way and then the center post runs to a power source that only sees voltage when the key is on. Typical circuits are ignition or radio. I attached a picture that shows how it wires as well.

  • Is it Necessary To Ground a Trailer Mounted Auxiliary Battery To Trailer Frame
    The way you currently have the system set up will work just fine for you. However, if you want to use the 12-volt accessory feed from your 7-way to maintain (not charge) the trailer mounted winch battery, the battery would indeed need to be grounded to the trailer frame. This is a very commonly found set-up, you would not need to worry about any problems between the vehicle and trailer battery. If the accessory circuit is used to maintain the battery, I would recommend installing a battery...

  • Does Wiring Batteries in Series Double the Batteries Amp Hours?
    Wiring your pair of 6V batteries in series will create 12V for your tear trailer. What it will not do is double your amp hour rating to 600 however. For that you would need to wire the batteries in parallel, though you would not have a 12V system if you did that.

  • Pin Functions on the Battery Isolation Solenoid # PK5231201
    The 2 pins on the side of the Battery Isolation Solenoid # PK5231201 are the input/output of the 12V power (it doesn't matter which is which) while the center pin is supposed to be connected to your ignition switch. I have attached a photo to demonstrate. Another thing you will need to note is that your 12V power pin and trailer brakes/brake controller signal are on 2 different pins (see attached picture of typical 7-Way wiring) unless you are referring to your breakaway switch. If your...
