The culprit for this is the protective integrated circuit with SMD mark UL46. It has the role of protecting the device from excessive voltage peaks. It's basically a Zener diode that gets damaged and creates a short or break. The easiest way to find the fault is to desolder the IC circuit one by one. And when it starts, the red LED only lights up. That integrated circuit is the problem. Only KESS can be removed, it will be functional but without protection. This is often the case when the device is used on cars that have a poor installation or is operated while the engine is running. |
