OTC 7645 Parasitic Battery Draw Test Switch.

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