Errors in fuse box repair
Many motorists underestimate the importance of regularly inspecting fuses to ensure they are working properly. Homemade fuses are often used. Of course, there are situations when you urgently need to replace a burnt out element. Then there is a temptation to use a homemade or Chinese fuse. This is strongly not recommended as it may damage the original electrical system of the vehicle.
Advice! Often, jumpers or commonplace paper clips are used as a protective element. To avoid short circuits or costly damage inside your vehicle, we recommend avoiding this practice.
It is important to understand that during repairs you need to pay attention to the fuse rating. Let us explain with an example: if a burnt-out PCB responsible for a car charger or cigarette lighter had a rating of 2A, then the replacement should be made with a part with the same resistance value. Ignoring compliance with ratings can lead to more serious and systematic breakdowns.
Replacing the fuse
To change you need to perform a number of steps.
- De-energize the on-board circuit.
- Open the protective panel of the mounting block.
- Remove the module from the slot.
- Here you should find the fuse link number F61.
- Next, using a special tool, remove the fuse from the socket and install a known good one in its place.
You can watch the video to see how to replace the part.
What is he responsible for?
The fusible element has two purposes. In the first modification and the version that underwent restyling in 2012, the essence does not change. The element is directly responsible for the cigarette lighter and the rear socket.
To relieve the load, some drivers install a “smoker” directly from the battery. This makes it possible to connect more powerful equipment to the outlet without the risk of damaging the system.
Fuse diagram
The standard fuse is located in the cabin module and is connected to the on-board circuit at the point where the wiring is broken in front of the consumers and the switch. The entire circuit is protected and there is no chance of damage.
Location
On the third generation Focus, the fuse is located under the glove compartment. The part stays in one place, no matter what modification of the body. It doesn't matter whether it's a station wagon, hatchback or sedan.
To gain access to the module, release the latches of the protective cover and remove it from its seat.
Here the insert is painted yellow and installed in the first left row vertically, fourth slot from the bottom.

Why does the fuse blow on Focus 3
In the event of a permanent failure, the line is checked in a certain sequence.
- Place the machine on a level surface and securely fix it.
- Disconnect power from the battery.
- Remove the cigarette lighter from the socket and check its integrity.
- If the element is intact, the wiring of the device itself and the rear socket is diagnosed. There may be damage to the wire in the circuit or the braiding of the line may be frayed.
- If the problem is not found, the mounting block is checked.
Which fuses to choose?
Ford Focus 3 is the first car in this series that is produced equally in all countries of the world. For Russia it is produced in Vsevolozhsk. The engineers' idea was fully realized, and original spare parts for the car can be found in any city in every country. The same applies to fuses that are manufactured in Russia.
Advice! Russian PPs are no worse than imported or European ones, but they cost an order of magnitude cheaper. We recommend paying attention to the domestic manufacturer.
