Ford D9ZZ-14526-H Circuit Breaker Assembly

The Fuse Panel is located inside the passenger compartment, under the drivers-side of the instrument panel. To replace a fuse, first turn the ignition switch OFF. Grasp the push-in type fuse with the provided tool, or a pair of needle-nose pliers. Look through the side of the fuse body to determine if the fuse element is blown. Check the amperage rating of the fuse which was removed and obtain a new fuse of the same rating. Align the fuse with its mounting position and push it into place until fully seated in the panel. Turn the ignition switch on and operate the accessory that was protected by that fuse. The Power Distribution Box is located under the hood, in the engine compartment. It houses the fuses and relays for most of the under hood components which are not controlled by a dash mounted switch such as the alternator, fuel pump, ECM, etc. The fuses and relays are replaced in the same manner as the fuse panel inside the vehicle. The power distribution box cover is hinged on one end and utilizes a retaining latch on the other. Simply release the latch and lift the cover up to gain access to the fuses and relays.

The electrical circuits of the vehicle are protected by a combination of fuses, circuit breakers and fusible links. The fuse block is located below the left side of the dash. Later models have two fuse blocks, one for standard fuses located under the instrument panel on the left side of the dashboard and one for high current fuses in the engine compartment, adjacent to the battery. Disconnect the cable to the negative battery terminal before replacing high current fuses. On earlier models the fuses are tubular glass body types while on later models miniaturized fuses are employed. These compact fuses, with blade terminal design, allow fingertip removal and replacement. If an electrical component fails, always check the fuse first. The best way to check a fuse is with a test light. Check for power at the exposed terminal tips of each fuse. If power is present on one side of the fuse but not the other, the fuse is blown. A blown fuse can also be confirmed by visually inspecting it. Be sure to replace blown fuses with the correct type. Fuses of different ratings are physically interchangeable, but only fuses of the proper rating should be used. Replacing a fuse with one of a higher or lower value than specified is not recommended. Each electrical circuit needs a specific amount of protection. The amperage value of each fuse is molded into the fuse body. If the replacement fuse immediately fails, don't replace it again until the cause of the problem is isolated and corrected. In most cases, the cause will be a short circuit In the wiring caused by a broken or deteriorated wire.

The electrical circuits are protected by fuses, fusible links and circuit breakers and the fuse panel is situated at the left end of the dashboard below the cover. The miniaturization of the fuses and the shape of the fuse block also make it possible to simply use fingertips to remove and install the fuses owing to the miniaturization of the elements and a blade-type terminal. Each of the fuses safeguards one or several circuits-names of which are inscribed on the surface of fuse's control box above the particular circuit; a fuse list is available, however, the most comprehensive data can be found in an owner's manual. If an electrical component stops working, the fuse must be checked; the new style fuses have a clear plastic body and if the appropriate fuse is removed and the clear plastic body is coloured, it means the fuse has blown. Before checking it should be turned to On position and each terminal at the top of the fuse should be tested by the toad of test light connected to the good ground. If the fuse is working properly the Lorestanis at both terminals will be charged, while if the fuse was blown the Lorestanis one side only is charged. Mortise is also advised to be checked visually for damage while the element of the lock is fixed which it sometimes is. Fuses should not be twisted when removed and inserted as it may cause damage to the terminal ends. Carbon fuses cannot be inserted with any type or amperage of fuse that will enable it to protect a circuit because the circuit's protection will be compromised if a bad fuse is used. The amperage value is usually engraved on the body of the fuses; and various colours signify various types of amperages. Before replacing a fuse, make sure all the electrical features and ignition are off and never replace a fuse with metal or foil, it is dangerous. In case the fuse has a tendency of blowing out as soon as it is replaced, the cause, which more often than not could be a short circuit as a result of damaged wires should be fixed before the fuse is put back.

The amperage value of each fuse is molded into the fuse body.

Do not replace it again until the cause of the problem is isolated and corrected. In most cases, this will be a short circuit in the wiring caused by a broken or deteriorated wire.

A blown fuse can be identified by inspecting the broken metal element inside the glass tube.

Fuse links can be identified by their green or black color and molded color identification tag.

The cover of the footwell fuse panel contains spare fuses.

A blown fuse can be confirmed visually by inspecting it.

The best way to check a fuse is with a test light. Check for power at the exposed terminal tips of each fuse.
