  • Test switch is used with an amp meter to isolate parasitic amperage draws on all GM vehicles or any vehicle with a side- or top-post battery
  • This tool attaches between the negative battery lead and the battery, then the vehicle road is tested
  • The next step is to connect an amp meter to each side of the switch, thereby allowing all available current to pass through the meter
  • Fuses are then removed one at a time until the circuit source of the parasitic draw is located
  • Similar to J-38758
