A Short Circuit Problem with the Fuse Panel on the Ford F350 Super Duty

Model: Ford F-350 Phn131 - Years 1999-2007
Part: Fuse box

In this video, we see what could be causing a short circuit on a Ford F350 Super Duty: the battery drains overnight, the headlights turn off, indicating a short circuit issue. The problem might be that water has entered the fuse panel and corroded all the electrical contacts. Fortunately, this model has a backup braking system that takes control of the brake booster; otherwise, it could have led to a serious problem. Inside the box, the electrical contacts are made up of six layers, and all were wet. Our YouTuber removed them and sprayed them with WD-40, but could not remove them all without breaking them, so he had to buy a new box. These boxes are very expensive: you can find them on AliExpress with the code 1005002545221933 for $203.83 plus $39.62 for shipping.

How to Bleed the Clutch on a Renault Clio?

To bleed the clutch on a Renault Clio, open the bonnet to access the components located in the engine bay: here, you will need to undo the screws that secure the battery in its housing, the intake manifold, and the coolant reservoir. This will allow you to locate the pipe through which the brake fluid flows: by inserting the other end of the pipe into a container, you can press the clutch pedal to expel all the fluid until it fills the container.
