Electric trailer jacks are convenient for RV users as they are easy to operate and reduce physical strain. However, they are susceptible to electrical failures and malfunctions. When diagnosing an electric trailer jack, it is important to first determine whether the issue lies with the power source or the jack itself. This can be done by checking the battery and verifying if other 12-volt components are functioning. If the problem persists, there could be an issue with the motor, ground connection, or inline fuse, which may require professional assistance. In some cases, manual cranking can be a temporary solution, but if the jack is unable to raise the trailer, it may indicate a faulty motor or a bad ground. Troubleshooting guides and service manuals can also provide valuable information for diagnosing and resolving specific issues with electric trailer jacks.

What You'll Learn
Check the battery
If your electric trailer jack is not working, there are a few things you can check to diagnose the issue. Firstly, check if the jack is getting any power. This can be done by testing other 12-volt components such as interior lights or a power awning. If these components are working, then the issue may lie elsewhere. However, if they are not working, then you may have a dead battery.
To further diagnose a battery issue, check the battery's voltage. A weak battery, even slightly below 12-13V output, can cause the jack to malfunction. If the battery is weak, you may need to replace it. Additionally, ensure that the battery is fully charged. A dead or weak battery can cause the electric trailer jack to become inoperable.
It is also important to inspect the battery for any signs of corrosion or debris. Corrosion or debris on the battery terminals can hinder the flow of electricity and cause the jack to malfunction. Clean the battery terminals if necessary and ensure all connections are secure.
In some cases, the battery may be functioning properly, but the issue lies with the ground connection. Check that the ground wire is securely attached to the battery and jack, and verify that the jacks are securely grounded to clean, bare metal surfaces. A faulty ground connection can disrupt the power supply to the jack, leading to its malfunction.
Finally, if your electric trailer jack worked with shore power but now only works with a battery, it could be an indication of a battery issue. As batteries age, they may lose their ability to sustain high amps, leading to insufficient power for the jack. In such cases, a converter can help transform shore power into the required voltage for the jack, but it may not always be sufficient.

Check the power supply
If your electric trailer jack is not working, there are a few things you can check to diagnose the issue. Firstly, ensure that the battery is in good condition and fully charged. A weak battery, even slightly below 12-13V output, can cause the jack to malfunction. Check that the battery is securely connected and free from corrosion or debris.
Next, verify that power is reaching the motor by using a circuit tester or meter. Test the power wire before and after the switch, and then at the motor. This will help determine if the issue is with the power supply or if there is a problem with the motor itself.
If the motor is receiving power but still not functioning, there could be a problem with the ground connection. Ensure that the jacks are securely grounded to clean, bare metal surfaces. Check for any signs of corrosion or damage on the ground wire, as this can interfere with the connection.
Additionally, check for blown fuses, as they are a common culprit when it comes to power-related issues. Refer to your service manual to locate the fuses and replace any that have blown.
If your jack is still not working, try plugging your trailer's 7-pin connector into your tow vehicle and starting the engine. This will help determine if the issue is specific to the jack or related to a broader power distribution problem.

Check the motor
If your electric trailer jack is acting up, there are a few things you can do to check the motor. Firstly, ensure that your battery is in good condition and fully charged. A weak battery, even slightly below 12-13V output, can cause issues with the motor.
Next, you should check the ground connection. Make sure the ground wire is securely attached and free from corrosion or debris. You can also check for a bad ground by using a circuit tester, like the #PTW2993, to test the power wire before and after your switch, and then at the motor. If there is power before the switch but not after, the switch is likely bad. You can also use a jump wire from the negative terminal of the battery to the negative side of the motor and hit the switch to see if the motor works.
If the motor is not working, it may be waterlogged. Water intrusion can cause the fuse or circuit breaker to constantly reset, indicating a short in the system. You can try using a manual crank to see if the jack works, but if not, you may need to replace the motor or the entire jack. You can attempt to disassemble, clean, and lubricate the motor, but if that doesn't work, you may need to contact a technician or replace the motor or jack.

Check the ground connection
If your electric trailer jack is not working, there are only three possible explanations: either power is not getting to the motor, the motor is bad, or the ground connection isn't working properly. To diagnose the issue, you should check the ground connection.
First, check that the ground wire is securely attached and that there is no corrosion or debris getting in the way of a solid connection. If your trailer lights are working, then the ground connection is likely working properly. However, if the lights work for a bit after hitting a bump, this could indicate an issue with the ground connection.
If your trailer has LED lights, they will need a good ground to illuminate. The metal part of the frame may serve as the ground, but a better way is to run a separate ground wire to each fixture on the trailer. If the bolts that connect the trailer frame and bed become worn, the two halves of the trailer will not have consistent metal-to-metal contact, resulting in an insufficient ground connection. This can be fixed by connecting the two portions of the trailer with a jumper wire.
If your trailer is equipped with electric brakes, you will need to jack up one wheel at a time. Connect the alligator clip to the "Electric Brakes" pin. If the "Ground" pin on the trailer is not working, none of the functions will work. You can also use a circuit tester to check the ground connection.

Check the fuses
If your electric trailer jack is malfunctioning, one of the first things you should do is check the fuses. Blown fuses are a common issue with electric trailer jacks, and they can be caused by a variety of factors.
To start, locate the fuse box. In some electric trailer jacks, there is only one fuse, which is located on the black wire where it enters the housing. In other models, there may be multiple fuses controlling the power supply, so be sure to consult your owner's manual for specific information on your jack's fuse box.
Once you have located the fuse box, inspect the fuses for any signs of damage or corrosion. If a fuse has blown, it will need to be replaced. You can typically find replacement fuses at your local home improvement store or through the jack's manufacturer. Be sure to purchase the correct type and amperage of fuse for your particular jack.
In addition to checking the fuses themselves, it is important to inspect the trailer jack wiring for any loose connections, frayed wires, or other damage that could be causing a short circuit and leading to blown fuses. Ensure that all connections are secure and that there is no corrosion or debris interfering with the connections.
If you replace a blown fuse and it continues to blow, there may be another issue with your electric trailer jack. This could include issues with the ground connection, the battery, or the motor. However, starting by checking and replacing any blown fuses is often the simplest solution and can save you from more costly repairs.
