Features and Benefits:

• 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.
