Starter Buddy for 12/24V Systems Starter Buddy tests the health of the vehicle’s electrical starting/cranking circuit. Slow cranks and no cranks are most likely caused by excessive voltage drops (resistance). If excessive resistance exists, starter buddy will help you quickly locate and diagnose which part of the circuit has the issue. Just 3 connections and a 3 second cracking test diagnose the problem. 12 foot test leads allow safe connections and control of the cranking test from the driver’s seat.
