Clamp onto the battery terminals and read the vehicle's dark current after the systems have gone to sleep. Remove fuses one by one the circuit that drops the reading is your drain source. No more blind guessing.
The integrated volt/current readout eliminates the need to connect a separate meter, reducing setup time and potential miswiring. Both hands stay free to work in tight engine bays.
Spring-loaded metal clips bite securely onto battery posts, keeping the connection stable while you pull fuses. The insulated ABS housing provides reliable protection during repeated use.
Beyond troubleshooting parasitic draw, check static current and charging voltage on a regular basis. Spot early signs of wiring aging or micro-shorts before they leave you stranded.
