• Part Needed to Protect Tow Vehicle Battery From Draining Overnight With Trailer Connected
  You can use a solenoid like the Battery Isolation Solenoid # PK5231201 which will keep your trailer from draining your vehicle battery while connected. This will isolate your trailer battery from the tow vehicle battery so power only flows from the tow vehicle battery when you are using the vehicle. This is a great option to make sure you aren't stranded with a dead vehicle battery.

• Recommended Brake Controller for 2017 Ford F-150
  Yes. All proportional brake controllers, like the Prodigy P3 # 90195 you asked from, have an accelerometer integrated that help it determine the braking pressure needed to proportionately apply the trailer brakes based on movement of the tow vehicle as well as the brake light signal. You can use a solenoid like # PK5231201 to cut the power to the brake controller if you desire, but I don't recommend it. The power draw on a brake controller when your vehicle isn't running is so minimal...

• How To Maintain Trailer-Mounted Winch Battery Using 7-Way 12-Volt Accessory Pin
  I do not recommend using the accessory circuit if it is attached to the reverse lights as it will only provide power when the vehicle is in reverse. But you can connect the 12 volt accessory pin to the vehicle battery using the following method. First, on the towing vehicle, you will need to install a battery isolator, # PK5231201. The flow of current will go from the vehicle battery to the isolator. From the isolator it will go along a length of 12 gauge wire, # 12-1-1, to the vehicle...

• Providing a Maintenance Charge on a 12 Volt Battery for Truck Bed Mounted Sprayer Using an Isolator
  The wiring on the 7-Way will not be sufficient to charge the break away battery and another battery on your sprayer. Instead, you will need to make a separate connection from the vehicle battery to the sprayer battery. You will need to use a battery isolator # PK5231201. Mounting it to the metal in the engine bay will ground it. Run a length of wire, # 10-1-1, from the positive battery terminal to one of the side posts on the isolator. Connect the center post (labeled 12V in the picture)...

• Options for Powering Stromberg Carlson Electric Trailer Jack
  Adding a battery to power an electric jack is without a doubt the preferred method. The jack will operate more quickly, reliably and efficiently. It is possible to connect the power lead of the jack to the 7-way accessory power feed from the 7-way, but the jack will operate very slowly. If the weight capacity of the jack is exceeded, the wire feeding the 12-volt power to the 7-way could possibly overheat. To install the battery on the trailer, use the 12-volt feed from the 7-way to maintain...

• Can 12 Volt Accessory Circuit of 2019 Ford F-350 Charge Trailer Battery
  Running a 10 gauge wire like part # 10-1-1 directly to the battery you have on your trailer would be a great solution to what you are wanting to do. The amperage would be low enough that you'd not need to worry about overcharging or hurting the battery at all. It basically would just keep the battery topped off at all times. Since the circuit on your truck is only active under the circumstances you listed too you wouldn't need to worry about it draining the vehicle battery either. You'd...

• Recommended Switch and Isolation of Two 12V Batteries
  We don't have anything to be a power selector quite like what you are describing. We have the isolation solenoid # PK5231201 that will only allow power to flow in one direction so the second battery cannot drain the first which a simple switch can be added to. The other option is to have two batteries run completely separate and use the Epicord Battery Disconnect Switch with Key - 50 Amp # 277-000096 on each one. This will isolate the on/off power of each battery, but what is connected...

• Can Trailers Batter be Charged by 7-Way Trailer Connector
  The 12-volt accessory feed from the 7-way CAN be used to maintain your trailer-mounted battery during travel, but it will NOT recharge a battery from a depleted state. This is the pin in the 1:00 position of your 7-way which has 12 volts on it at all times. To charge a depleted battery, a charger like the NOCO Genius Battery Charger and Maintainer # 329-GENIUS5 can be used. The 10 or 12 gauge wire used in the accessory circuit will prevent enough current from going through to worry about...

• Charging a Trailer Battery from the Tow Vehicle Battery
  There is no need for a charger or controller to give a maintenance charge to your trailer battery while towing it. You simply need to use 10 gauge wire # 10-1-1 along with a 40 amp circuit breaker # 9510 in-line. So you will run a short wire from the vehicle battery to the circuit breaker and then a long wire from the circuit breaker to the 12V power at your vehicle side 7-way. Your trailer side plug will then have a wire that will run to the positive terminal of the trailer battery...

• Battery Isolator for 1991 Jamee Motorhome to Prevent Battery Drain
  In motorhomes with multiple batteries there should be an isolator already in place that prevents the main battery (that starts the engine) from being depleted by the auxiliary battery that powers the interior lights. An example of such an item is the part # PK5231201 which acts like a switch that opens and closes. This is rated for 100-amps. We also offer other isolators # DW08770 (95-amps) and # DW08771 (120-amps). Battery power will pass between the left and right terminals only when...

• Battery Solenoid Recommendation for a Trailer Battery Charge Wire to Prevent Battery Drainage
  We have a solenoid that will do exactly what you are trying to do. You would want a Battery Isolation Solenoid # PK5231201. You would run the keyed power source to the middle terminal and then splice the other terminals inline with your 12 volt power charge circuit. In order to find a good circuit to use I would recommend you find an accessory that only gets activated when the key is on and then tap into the power side of that circuit. On my car I used the power antenna wire and the traction...

• Can Push to Test Breakaway Charging Light be Turned Off When Trailer is Connected to Tow Vehicle
  As long as the trailer is connected to the tow vehicle and the battery isn't fully charged the single yellow LED charging light will be on. This is because the 12 volt circuit is always active in the vehicle side trailer connector. The single LED light draws such little power that it would likely take weeks if not longer of it just sitting with that light on to drain the battery. Bit there is a way that you can remove power from the 12 volt circuit when the truck is turned off. You could...

• Wiring In-Bed Truck Camper Running Lights and 12 Volt Circuit to 2012 Toyota Tacoma
  Tapping into the vehicle's 4-Way trailer connector for running lights will work great. It is the pin next to the ground pin, usually a brown wire. The aftermarket 4-Ways for the 2012 Toyota Tacoma are all going to be circuit protected so you would not have to worry about that circuit causing any trouble with the vehicle wiring. You would not have to use diodes for the 12 volt circuit. What I recommend is 10 gauge wire, # 10-1-1 sold by the foot, and a circuit breaker such as # PK54520...

• Do Circuit Breakers Provided with ETBC7 Have Diodes to Prevent Car Battery Discharge
  The breakers included with the # ETBC7 Brake Controller Installation Kit don't have diodes. If you're worried about unintentional power draw on that 12V trailer accessory feed discharging the vehicle battery, you can install an isolator solenoid like # PK5231201 which will shut down that feed when the vehicle ignition is turned off. The solenoid would install inline on the 12V circuit from the battery, with the center terminal ran to a ignition switched circuit.

• How to Wire Two Batteries In Parallel on an RV Trailer
  When connecting two batteries together on an RV trailer you usually connect the batteries in parallel to draw 12 volts from both of the batteries. We have a photo, see photo at right, that shows how to wire the batteries in parallel. Once you have the batteries wired properly in parallel you will need to connect the 12 volt power wire from the trailer 7-Way connector to the positive wire on the first battery. This connection will help maintain the batteries when the vehicle is running,...

• How To Maintain Trailer-Mounted Winch Battery Using 12-Volt Accessory Feed
  First, on the towing vehicle, you will need to install a battery isolator, # PK5231201. The flow of current will go from the vehicle battery to the isolator. From the isolator it will go along a length of 12 gauge wire, # 12-1-1, to the vehicle side trailer connector via a 30 amp circuit breaker. Next, 12 gauge wire will need to run from the trailer side 7-Way to the positive Trailer battery terminal. If the winch came with a circuit breaker it will need to go between the winch and positive...

• Is a Battery Isolator Needed for 7-Way Wiring on 2001 Ford F250
  The 12-volt power source at the 7-way connector is typically protected by a 40 amp fuse or breaker. This circuit is usually tied directly to the battery, with the fuse or breaker installed inline. This circuit is not isolated. Because this circuit can remain live even when the ignition is switched off (depending on the vehicle), we recommend unplugging the trailer when the vehicle is not running to avoid the battery from being discharged. If you wish to avoid this problem altogether, using...

• How Does The Battery Isolation Solenoid Work?
  The Battery Isolation Solenoid, # PK5231201, is not the same thing as a starter solenoid or the Ford solenoid but could be used in a similar way. This solenoid is intended to isolate the power to the trailer so it doesn't drain the battery of your towing vehicle when the ignition is switched off. It is rated for 100 amps. This protects your trailer from draining your vehicle battery while still connected and leaving you needing a jump start or forgetting to plug in your trailer back...

• Setting Up Australian-Market 2010 Hyundai Santa Fe to Tow Trailer With Electric Brakes
  In the US market, Hyundai does not pre-wire the Santa Fe for electric trailer brakes. From my research online, I found that an Australian 7-way flat trailer connector does use the blue wire in the # 5 position to carry trailer brake output voltage. To actuate your brakes, you would need to install a brake controller. Your vehicle might be pre-wired, you would need to check with a local Hyundai dealer about that, there might be an adapter harness available that would make installation...

• Ways to Wire Multiple 12V Batteries
  Multiple batteries can be wired either in parallel or series configurations to deliver either increased amp-hours or increased voltage. Eight 12V batteries wired in parallel will deliver the same 12V output but with a longer amp-hour capacity. Eight 12V batteries wired in series will deliver more voltage (8 x 12 = 96 volts) with about the same amp-hour capacity. If your solenoids are burning out in your application you will want to use a higher-rated unit.
