• Will Flat Towed Vehicle Charge Line Kit Prevent Back-Feed and Overcharging?
  The Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 has a circuit breaker to help isolate that circuit from issues, but it will not prevent back-feeding. If you want to prevent back-feeding which isn't typically an issue, you can use the Roadmaster Single Park Light Diode # RM-690. Because you are sharing power between two batteries at a low amperage there is very little risk of a surge issue. Another option is to use the Battery Isolation Solenoid # PK5231201 which...

• Does Dexter Axle Brake Actuator Draw Tow Vehicle Battery Power While Parked?
  The Dexter DX Series Electric Over Hydraulic Brake Actuator for Drum Brakes - 1,000 psi # K71-650 should have a draw on the truck battery. The draw is dependent on the truck itself as many vehicles will allow the draw for a limited time before shutting down. There shouldn't be an output from the brake actuator, so you shouldn't have an issue with long term parking. If you are concerned about losing your battery power in the vehicle, then you can unplug the trailer or if you want to...

• How Does Battery Isolation Solenoid Wire Up to Prevent Vehicle Battery Drain
  The Battery Isolation Solenoid # PK5231201 is exactly what you need to deactivate your trailer wiring 12 volt circuit when your 2017 Ram 2500 is turned off. So what you need to do is cut the wire that leads to the pin in the 1:00 position of your 7-way while leaving enough room to reconnect it and then run both sides of that wire to the larger outside posts of the solenoid. Then you need to run a circuit that only sees power when the key is on to the center post of the solenoid. This is...

• Battery Isolation Solenoid # PK5231201 Not Switching Off 12V Supply on 2004 Toyota Tundra
  The Battery Isolation Solenoid you referenced, part # PK5231201, installs as you described: the 12V battery feed enters at the left-hand terminal; the center terminal connects with a fuse tap to one of the ignition-controlled circuits in the vehicle (such as the radio or powered antenna); the right-hand terminal is the 12V output to your camper battery. I have attached a photo showing these connection points, just for reference. I also pulled two samples from our stock and tested them both...

• Is a Battery Isolator Needed when Adding a Battery to a Trailer
  First, the 12 volt circuit from a trailer connector, and most factory alternators on vehicles, are not able to charge up a trailer mounted battery. What they will do is provide a maintenance charge and keep the trailer battery at its current charge level. A battery isolator will only send power back when the vehicle is running. This will help to keep from draining the vehicle battery. Or you could just disconnect the trailer from the tow vehicle when you stop for long periods of time....

• How to Make 12 Volt Accessory Circuit of 2015 Silverado 3500 High Country Only Active With Key On
  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, will activate the circuit so that the 12 volt accessory circuit would only get activated when...

• Wiring In-Bed Trailer Wiring 12 Volt Power to a Switched Ignition Source on a 2004 Chevy Silverado
  The AUX can be a power source if connected to the battery. Normally on a 7-Way, the center pole is either AUX or reverse lights. I recommend using the center pole for the reverse lamps since you can wire the 12 volt hot lead to be on a switched ignition source if you wanted. Basically what you would do is find a 12 volt power wire that is only hot when the truck is on. That way it will turn off when you shut off the key. One way to do this would be to use a battery isolator, # PK5231201....

• Adding Interior Lights to Trailer and Keep Battery Charged
  The best way to get interior lights in your trailer is to have a dedicated 12 volt battery, and battery box like # 329-HM318BKS mounted to the trailer. This gives you the power needed while you're not hooked to your truck. For lights I recommend LEDs because they require much less power, and last longer than incandescent bulbs. Which lights I recommend depends on how many you want to add and the way you want to mount them. You'll need wire # 12-1-1 and ring terminals # 44-5310A for each...

• Battery Isolation Solenoid to Protect Vehicle Battery from Discharge from Trailer
  You can easily run a 12V charge line to the battery that will power the winch on your trailer. Your existing 7-way setup includes a 12V circuit that also charges your breakaway battery. Inside the junction box you will make an additional 10-gauge wire connection at the post for the 12V auxiliary circuit and run this to the positive post of the winch battery. You can use bulk wire # 10-1-1 and ring terminals # 44-5310A. Your 12V feed should already have a fuse/breaker on it. To protect...

• How to Wire a Battery Isolation Solenoid to Maintain a Charge on a Trailer Mounted Winch Battery
  The Battery Isolation Solenoid # PK5231201 is one part that I would recommend using to cut-off power to the winch battery when you are not in tow with your trailer. You can wire the 12-volt accessory power wire on your trailer connector through the 7-way connector to get the maintaining charge from your vehicle to your winch battery. I also recommend wiring in a 40 amp circuit breaker like # PK54540, if you do not already have one, in-line on the power wire running to your winch/trailer...

• Can 16 Gauge Wire be Used for Battery Isolator Solenoid
  Yeah you definitely need to be running at least 10 Gauge Wire # 10-1-1 for the Battery Isolation Solenoid # PK5231201. The 16 gauge wire size is typically used for vehicle and trailer lights which don't draw nearly as much power, but for the 12V power that's charging your trailer battery you really need larger wire. As long as you're using the larger wire and you have the isolator solenoid installed with a good ground any heat you see it build up isn't something to worry about. It'll probably...

• When Using a Battery Isolator Prevent the Trailer Battery from Draining the Vehicle Battery
  The isolator # PK5231201 will only send power back on the output wire when the ignition source is energized (vehicle is running). This will prevent the trailer from drawing power from the vehicle battery or back feeding to the vehicle battery and will also maintain the charge level of the battery (when the vehicle is running). However, you will not be able to charge up the trailer mounted battery. For that you are going to want to use a battery charger like # CTEK56353. If you are just...

• Fuse Tap for Installation of Battery Isolation Solenoid PK5231201
  Yes, you need to use a different circuit to trigger your battery isolation solenoid. Typically one of the circuits controlled by the ignition key is used - often the circuit for a power antenna is a good choice. You would use a fuse tap like # F2526 to access the ignition-key-controlled signal and route this to the center post on isolation solenoid # PK5231201.

• What Ignition Power Source Can I Use on a 2013 Toyota Highlander With Part # PK5231201
  The ignition source is a signal used to tell the Battery Isolation Solenoid part # PK5231201 to turn off/on. You can use any power source on the vehicle that only receives power when the vehicle is on such as the radio. The radio fuse is located in the engine compartment fuse box. It is a 20 amp fuse in the number 26 position. I have attached a photo of this location for you.

• Isolator Recommendation to Prevent a Trailer Battery from Draining a Vehicle Battery
  If you have a 7-way installed on your vehicle and trailer and the 12-volt power circuit goes to a battery installed on the trailer it will lightly charge the battery when the connectors are connected. You should note that it will not charge a dead battery back to life, but it will more or less maintain a good charge on a battery if it is in good shape already. If you are worried about your trailer draining your vehicle battery if the connectors are left together you have two options. First,...

• How to Prevent a 12 Volt Power Circuit on a 7-Way from Being Active All the Time
  What most people use to allow the 12 volt charge wire from being hot all the time and only when the key or the vehicle is on is an isolation solenoid part # PK5231201 on the charge wire. You basically run the center pin to a keyed power source and then run one side of the solenoid to the 7-way and the other to the wiring of the truck. If you were wanting to install it on a 4-pole connector that was used strictly for that circuit that is possible too. This wouldn't work through a 7-way...

• Tapping into a 12 Volt Source on a 2001 Chevy Silverado
  What you may need to do is splice into one of the wires going into the radio that is only hot when the car is on rather than use a fuse tap. Or any accessory that only receives power when the ignition is on such as a radio, antenna, windshield wipers to name a few. If you are looking at the 12v sticker on the solenoid # PK5231201, right above it will be the auxiliary center post which is usually attached to an ignition switch wire.

• Battery Isolation Solenoid Not Working Properly on 2001 Chevrolet Silverado
  First I would look at what you have mounted the isolation solenoid # PK5231201 to. You will need to mount the isolation solenoid to a metal surface. The unit grounds through the mounting location. It will not function if it is attached to plastic so you will need to locate sufficient metal space so it will function correctly. I can't tell from your photos if you are mounting the isolation solenoid to a plastic or metal surface. The ground you have made to one of the screws holding the unit...

• 12 Volt Pin on Aftermarket 7-Way on a 2000 Toyota Tacoma is Hot All the Time
  On some vehicles, the 12 volt circuit is hot all the time. Since you hardwired in the # ETBC7, it is directly connected to the battery via a 40 amp circuit breaker so it should be hot all the time. This is nothing to be concerned about unless something is plugged in and drawing power. Just remember that if you will be parked for a long time, disconnect the trailer! If there is nothing on the trailer that uses the 12 volt pin then you will not have to disconnect the trailer. Even though...

• LED Indicator Light on Curt Trailer Wiring Harness Is On All the Time On 2013 Dodge Grand Caravan
  The Curt trailer wiring harness for the 2013 Dodge Grand Caravan is # C56331. I could not find information on a 56187. The correct harness does not have an LED indicator light on it anywhere. There are some adapters, like # C57674, that have LED indicators to tell you a circuit is working on or not. In this situation the 12 volt indicator light will always be on because the 12 volt circuit is hardwired directly to the battery. In order to not have it come on it would have to be wired to...

• Where to Get 12 Volt Ignition Source Power for a battery Isolator on a 2003 Toyota Tacoma
  There are various circuits that are only hot when the vehicle is turned on. The radio is one. You could find the fuse that powers the radio and then use a fuse tap to tape into it and wire it to the center post on the isolation solenoid # PK5231201. Use the vehicle owners manual and/or legend on the power distribution box lid to locate a relevant fuse. Fuse taps are available at auto parts stores.

• How to Install 12V Battery Isolator to Prevent Vehicle Battery Drainage by Trailer Battery
  If the vehicle 7-way's 12V power circuit remains active when the ignition is off, you will want to install an isolation solenoid # PK5231201 to prevent the trailer battery from depleting the vehicle battery. You can test the vehicle 7-way pin at the 1-o-clock position (please see the linked photo) with a tester like # PTW2993 to determine if this 12V circuit is ignition-controlled or always active. If it stays active all the time, then the isolation solenoid will prevent the trailer battery...

• Can 7-Way Junction Box 277-000141 Be Used to Charge Trailer Battery
  If there happened to be a 12 volt keyed power source in the circuits of the # 277-000141 you could use it for the isolation solenoid # PK5231201. Essentially you would need to have the 12 volt circuit of the vehicle already be only active when the key is on. Which if that were the case you wouldn't need the solenoid realistically. If the 12 volt circuit of your truck's 7-way is active all the time you would need to install the solenoid on that circuit and that would get the circuit active...
