So Fix it

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.

Cars use many different systems to operate properly. They have a fuel system, an exhaust system, a computer system and an electrical system. Both the computer and electrical systems have wires that relay current and information to different parts of the vehicle. Recognizing the different wires not only aids in repair, but it can help a driver troubleshoot problems before they occur.

Battery Cables

Battery cables come in three main types: SGR, SGX and SGT. All three types have thick copper cores. The difference comes in the insulation type. SGR stands for Starter or Ground General Purpose Ground Rubber. This means the wire is strong enough to handle high voltage and is insulated with rubber. SGX wires copper stranded cables are insulated with cross linked polyethylene. This protects the wire at a higher temperature. SGT wire is insulated with thermoplastic. This is a material that protects the wires up to a temperature of 250 degrees Fahrenheit.

Silicone Rubber Motor Lead

Silicone Rubber Motor Lead, or SRML, is used in the hottest parts of the engine. This type of wire has a tin and copper core. It is insulated with a silicone and rubber layer and covered with braided fiberglass. This is the wire with highest temperature tolerance in a car. This wire is heat resistant to almost 400 degrees. It is used for everything from wiring lighting in high-temperature places to carrying electrical impulses to the motor.

Brake Wire

Brake wire is part of the electrical brake system. In an electrical brake system, brake fluid and mechanical junctions are replaced with an electrical signal that is sent from the brake pad to the brakes. This wire is made of copper and has polyvinyl insulation. It is heat resistant to more than 220 degrees.

Automotive Primary Wire

Automotive Primary Wire is the most common form of wire used in a car. This is the wire that carries voltage to lights, the dashboard, electrical windows and locks, GPS, stereo and other electrical devices in the car. These wires also carry information from the cars onboard computer to the engine, exhaust system and other areas that the computer monitors. This wire is made of copper and insulated with cross-linked polyethylene.

Speaker Wire

Speaker wire is used in cars just as it is used in the home. Since it carries a very low electrical charge and doesnt require protection from higher temperatures that a wire in the motor needs, it is insulated in polyvinyl chloride. There are two wires, each insulated separately, in a strand of speaker wire. One is tin and the other is copper. This wire is used to carry signals from the stereo system to the speakers.

A spark plug is an electrical device in the ignition of a vehicle that ignites gas by using an electric spark. Spark plugs are made up of an insulated wire and electrode, an ignition coil and a spark gap inside the interior. Spark plugs typically need to be changed every 30,000 to 45,000 miles to keep the ignition running smoothly. These tools will help you replace or repair your spark plug wire.

Lisle Wire Puller

The Lisle Wire Puller removes the spark plug using rubber cushioned jaws to grip and pull. They are adjustable to five positions so you are able to access the spark plug from different angles. The plastic handles help to prevent you from getting shocked by the spark plug.

Lisle Plug Remover

The Lisle Plug Remover removes broken spark plugs using a thread to pull the plug from its head. It comes with a porcelain pusher to press the porcelain in the tip of the plug, preventing the porcelain from breaking.

ACCEL Pliers

The ACCEL pliers make gaps in spark plugs. They are specially aligned to make the outer electrode perpendicular to the center electrode. They are made of a steel frame with a rubber, non-slip handle.

Pro Crimp Spark Plug Wire Tool

The Pro Crimp Spark Plug Wire Tool is a specialty tool made for crimping spark plug wires. It can cut, strip and crimp wire that is up to 8.5 mm in diameter. The frame is made of heavy-duty steel with a soft plastic, non-slip handle for comfort.

Weatherpack Weather Pack Crimper Tool

The Weatherpack Weather Pack Crimper Tool is made for heavy-duty crimping of wires ranging in sizes from 20 to 14 gauge. It has an orientation block, two double cavities and a ratchet mechanism for reliable crimping.

ACCEL Terminal Crimping Jaws

ACCEL Terminal Crimping Jaws are for crimping 7 mm to 8 mm spark plug wires. They are made of steel with a black oxide finish for high pull strength.
