Blue-Point Parasitic Draw Monitor

Engineered for professional automotive workshops that need to diagnose excessive battery drain on modern vehicles with complex sleep-mode electrical systems, the Blue-Point Parasitic Draw Monitor provides a safe, reliable method of measuring parasitic current draw with the vehicle fully closed and undisturbed — eliminating the false readings caused by door-open wake events that defeat conventional ammeter-based parasitic drain testing.

Key Features:

• Parasitic draw monitoring with door closed allows the vehicle's electrical system to enter full sleep mode before current measurement begins, ensuring the reading accurately reflects the true resting current draw rather than an active or transitional state triggered by an open door.
• Prevents false wake events during testing by eliminating the need to keep the vehicle door open or disturb the body control module, CAN bus, or other sleep-sensitive systems while monitoring current — a critical requirement on modern European and Asian vehicles with complex body electronics.
• Identifies parasitic drain faults accurately by capturing the current draw after all vehicle systems have fully powered down, enabling the technician to pinpoint the circuit or module responsible for excessive battery drain with confidence.
• Suitable for all modern vehicle types including those with advanced sleep-mode management, keyless entry, telematics modules, and multiple CAN bus networks that are easily disturbed by conventional parasitic drain test methods.
• Blue-Point professional quality delivers the durability and reliability expected from the Blue-Point brand — a Snap-on company — ensuring accurate, repeatable results in daily workshop use.
• Compact and easy to use design allows the monitor to be set up quickly between the battery and the vehicle's electrical system, minimising preparation time and getting the parasitic drain test underway without delay.
