An electric tongue jack is an essential tool for RV enthusiasts. It makes it easy to hitch and unhitch your trailer without having to crank a manual jack. However, it can be challenging to install and wire the tongue jack correctly. In this article, we will provide you with a comprehensive electric tongue jack wiring diagram along with FAQ and tables to help you make the process smooth and hassle-free.
Overview of Electric Tongue Jack
An electric tongue jack is a device that is attached to the hitch of a trailer to lift the front end of the trailer. It is powered by a motor that runs on electricity from the battery. The jack makes it easy to maneuver the trailer in tight spots, level the trailer on uneven ground, and prevent back strain associated with manual cranking.
The electric tongue jack consists of several components such as the jack, motor, switch, battery, and wiring. The wiring is critical as it connects all the components and ensures that they function correctly.
Electric Tongue Jack Wiring Diagram
Before you start wiring the electric tongue jack, ensure that you have the necessary tools such as wire strippers, crimpers, connectors, and electrical tape. Here is a step-by-step wiring diagram that you can follow:
Step 1: Disconnect the Battery and Ground the Trailer
The first step is to disconnect the battery to avoid electrocution or damage to the electrical components. Next, you need to ground the trailer to prevent electrical shocks. You can do this by attaching a ground wire to the metal frame of the trailer.
Step 2: Identify the Wiring Components
Identify the wiring components such as the battery, motor, switch, and jack. The wiring colors may vary depending on the manufacturer, so be sure to check the manual for the correct color codes.
Step 3: Wire the Battery to the Switch
Connect the positive wire of the battery to the positive post of the switch. Next, connect the negative wire of the battery to the ground post of the switch.
Step 4: Wire the Switch to the Motor
Connect the positive wire of the switch to the positive post of the motor. Next, connect the negative wire of the switch to the negative post of the motor.
Step 5: Attach the Motor to the Jack
Attach the motor to the jack by aligning the mounting holes and securing it with bolts. Then, connect the wires from the motor to the jack using connectors.
Step 6: Test the Electric Tongue Jack
