How to Wire a Twist Lock Fuse Holder

How to Wire a Twist-Lock Fuse Holder

Twist-lock fuse holders protect the electrical system of your vehicle from spikes in voltage, amperage and equipment short circuits. The design of the fuse holder allows the fuse to sit in line with the electrical wiring it is protecting. This allows you to install a twist-lock fuse holder in tight places in the vehicles engine compartment, under the dash or in the trunk. Installing a fuse holder correctly requires the same tools and techniques as other types of electrical wire installation.

Instructions

    1

    Open the hood of your vehicle. Remove the ground cable from the vehicle battery by loosening the battery clamp bolt with an adjustable wrench and pulling the loosened cable from the battery post.

    2

    Cut the wire loop midway between the two connected halves of the twist-lock fuse holder with a pair of wire cutters. Remove 1/2 inch of insulation from both ends of the cut wire with a pair of wire stripper/crimpers.

    3

    Cut the "hot" wire that requires the fuse, using the wire cutters. Strip 1/2 inch of insulation from each end of the cut wire as earlier described.

    4

    Slide one stripped end of the hot wire in one end of a crimp-style connector and one stripped end of the fuse holder wire into the other end of the connector. Place the crimping section of the wire stripper/crimper over the center of the connector. Depress the crimper handles to add a center crimp to the connection. Place one additional crimp on either side of the center crimp to secure the wires.

    5

    Repeat the procedure to secure the second stripped end of the fuse holder wire with the second stripped end of the hot wire.

    6

    Reconnect the ground cable to the vehicle battery. Tighten the battery post clamp with the adjustable wrench.
