The Parasitic Draw Tester Accessory is designed to allow you to directly connect between the vehicles battery and battery cable with a fuse protected and switch enabled connection that you can safely stack into. If you have gotten to the point in your diagnosis that you need to sit between the battery and battery cable, this accessory lets you safely and effectively track and chase down parasitic drains faster. 
 
Also by using this accessory in conjunction with the Fuse draw mode of the N2 Neuron you can create a draw tester that can handle the highest mini fuse rating available. (Video Coming Soon)
