Greetings, everyone!

Today, we are excited to share that we have successfully repaired a broken Fakra cable end, a commonly used component in vehicle stereo and video connections. Instead of opting for expensive solutions such as replacing the entire engine bay harness or adding a new cable alongside the damaged one, we took matters into our own hands and skillfully soldered on a new Fakra connector. Incredibly, our repair work may even surpass the quality of the original connection.

What truly sets Grease Monkey apart, especially in the Saint Louis area, is our exceptional ability to tackle a diverse range of challenges that others may find daunting or simply shy away from. We hold ourselves to the highest standards and strive for perfection in every task we undertake, fully aware that absolute perfection is an unattainable goal. However, our unwavering dedication to pursuing perfection enables us to consistently deliver outstanding results.

We are proud to serve our community with our expertise and commitment to excellence. Thank you for your continued support and trust in our services.

Hello everyone

This is a set of components for a 2006 Ford F250 Super Duty 6.0, including the FICM (Fuel Injection Control Module), ECM (Engine Control Module), and the power supply inside the FICM. In the last picture, you can see the data showing the readings from a scan tool, indicating the voltage of the new power supply.

We obtained these components from a shop for testing because they were unable to communicate or interact with them. While we were there, we decided to test the common failure point of these components, which is the power supply. It is Inside the FICM. The power supply tested bad at 12 volts, which should ideally be a steady 48 volts. We replaced the power supply, and the new one tested good with a steady 49 volts (as shown in the picture).

We are uncertain if the power supply alone was the issue or if there are other factors involved. We expect to have more information very soon. We are dropping these back off this Wednesday.

Just a few things we love doing. ❤️
