Lisle Parasitic Drain Tester

The Lisle Parasitic Drain Tester is a specialized tool designed to facilitate the diagnosis of hidden battery drain in vehicle electrical systems.

1. Functionality: The tester provides a straightforward method to connect a multimeter to the vehicle's electrical system, enabling precise diagnosis of parasitic battery drain. - It allows automotive technicians to identify and measure current draw that could potentially drain the vehicle's battery when it's not in use.

2. Protection Features: Replaceable in-line fuses are integrated into the tester to protect both the multimeter and the tester itself in case of a high current source being left on in the vehicle. - A switch bypasses the multimeter during connection to prevent damage from power surges, ensuring the safety of both the testing equipment and the vehicle's electronics.

3. Extended Testing Capability: The tester is designed to remain connected to the multimeter until other vehicle computer systems shut down, allowing technicians to isolate and measure the parasitic drain accurately. - Stacking banana connectors on the tester provide convenience, allowing voltage measurements to be taken at various points on the vehicle using standard test leads.

4. Application: Essential for automotive technicians and mechanics performing diagnostics on vehicles experiencing battery drain issues. - Facilitates efficient troubleshooting and identification of electrical faults that could affect vehicle performance and battery life.

Overall, the Lisle Parasitic Drain Tester is a reliable tool that enhances the efficiency and accuracy of diagnosing hidden battery drain in automotive electrical systems, ensuring optimal vehicle operation and maintenance.
