Setup and Installation

This section outlines the steps for installing the JQ-3500B electric tongue jack onto your A-frame trailer. Ensure the trailer is securely chocked and supported before beginning installation.

Removing the Existing Jack

1. Park the trailer on a level surface and chock the wheels to prevent movement.
2. Support the trailer tongue using jack stands or a suitable alternative to relieve pressure from the existing jack.
3. Disconnect the power to the existing jack, if applicable.
4. Unbolt the existing jack from the trailer A-frame. Typically, there are three bolts.
5. Carefully remove the old jack.

Installing the JQ-3500B Electric Tongue Jack

1. Insert the new JQ-3500B electric tongue jack into the mounting hole on the trailer A-frame.
2. Align the mounting holes on the jack with the holes on the trailer A-frame.
3. Place the provided star washers between the jack's mounting plate and the trailer frame to ensure a good metal-to-metal contact for proper grounding.
4. Secure the jack using the supplied Grade 5 hardware (bolts and nuts). If your coupler does not have tapped holes, use the supplied nuts to secure the jack. Tighten the fastening hardware to 15 foot-pounds using a torque wrench.
5. Attach the drop leg to the bottom of the jack using the linchpin. Adjust the drop leg to the desired height before lowering the jack.

Electrical Connection

1. Ensure the trailer battery is disconnected before making electrical connections.
2. The jack comes with a black wire lead. Install a ring terminal to this black wire lead.
3. Route the black wire lead safely along the trailer frame to the positive terminal of the 12V deep cycle marine-grade battery. Secure the wire to the frame using cable ties.
4. Connect the ring terminal of the black wire to the positive (+) terminal of the battery.
5. Reconnect the negative (-) terminal of the battery.
6. Note: The jack cannot be powered through the 7-way connector. An additional inline fuse is not necessary as this jack is equipped with a built-in circuit breaker that automatically trips and resets.
