The Electric Motion PDT Heartbeat 1001 parasitic drain tester is an automotive diagnostic tool for 12V battery systems commonly used on cars and trucks to give a conclusive pass/fail result. It features special software and a battery interface designed to allow to test 100 percent of the vehicle by never breaking contact with the current so testing goes uninterrupted. The tool also features audible alerts that will assist the technician in diagnosing and repair. With minimal technical ability needed, the tool can save time and money by taking the guesswork out of parasitic drains, the company says.
