OTC 7645, Battery Drain Tester Switch

Features and Benefits:

OTC7645

  • Finding electrical problems that drain the battery is getting harder all the time. But using the 7645 with your digital amp meter takes the guesswork out of a complicated job.
  • Attach the test switch between the negative battery cable and the battery, and then road test the vehicle.
  • Next, connect an amp meter to the switch to determine the parasitic amperage draw, and locate the excessive electrical drain on the battery.
  • Works on any vehicle with side or top post batteries.
  • Wt., 8 oz.
