Where are the common areas prone to electrical leakage in Ford Focus?

Usually, the navigation system is prone to electrical leakage, especially when an aftermarket navigation system is added to the Ford Focus. Related information: 1. Introduction: The Ford Focus, with 'Focus' meaning the center of attention, is one of the flagship models of Ford Europe. One year after the launch of the sedan version, Changan Ford introduced three hatchback versions of the Focus, corresponding to the 1.8L manual Classic, 1.8L automatic Fashion, and 2.0L manual Sport and 2.0L automatic Sport versions of the sedan. 2. Design: The entry-level engine displacement of the Focus was reduced from the previous 1.8L to 1.6L. However, due to the adoption of more advanced technologies, the maximum power only decreased by 1kW to 91kW/6500rpm, while the maximum torque even increased by 2N•m to 159Nm/4000rpm. Therefore, the power of the entry-level models remains largely comparable to the previous versions. Additionally, the use of a 6-speed dual-clutch automatic transmission has further reduced fuel consumption.
I've been driving a Ford Focus for many years and have encountered battery drain issues several times. To summarize, there are several common areas to pay attention to. First, let's talk about aftermarket installations, such as adding audio systems or navigation. If not installed properly, the wiring can easily short-circuit, especially near the trunk or the junction box by the driver's seat. Then there are the factory modules, like the BCM (Body Control Module). Older models of the Focus might malfunction due to dust or moisture, causing the battery to drain completely. Wiring aging is also a big issue, particularly with the wiring harness under the chassis or near the door locks—over time, wear and tear can lead to leakage. Additionally, door lock sensors, if not properly closed, can prevent the system from entering sleep mode after locking, leading to slow current drain. The alternator or the battery itself might also be faulty, but don’t rush—start by checking simpler things first, like using a multimeter to measure the current. If the resting current exceeds 50mA, you’ll need to investigate carefully. Regular cleaning and inspection of the wiring harness can prevent these issues, saving you from being stranded on the road.
