Mobile Electrical Parasitic Current Drain Tracing & Diagnosis

If your car battery keeps dying repeatedly after sitting parked overnight—even after you have recently installed a brand-new battery—your vehicle is likely suffering from a parasitic electrical drain. In modern feature-rich automobiles, dozens of electronic modules are designed to enter a low-power 'sleep mode' several minutes after the ignition is turned off and the doors are locked. However, a malfunctioning door lock microswitch, a sticking relay, a faulty glovebox light, an improperly wired aftermarket dashcam, an active GPS tracking unit, or a shorted control module can prevent the CAN-bus network from sleeping, continuously pulling current from the battery.

Our mobile parasitic drain diagnostic service uses specialized electrical testing equipment to isolate the exact circuit responsible for draining your battery. Our technicians set up inline digital multimeters and non-intrusive DC milliamp clamp meters to measure the exact resting current draw. By systematically monitoring micro-voltage drops across all interior and engine-bay fuse boxes without waking up the vehicle's computer networks, we pinpoint the exact faulty module, aftermarket accessory, or shorted wire causing the issue.
