The Fuse Monitor (PPFUSE) is used to locate / isolate which circuit parasitic draw lies on by measuring current across fuses without removing them. The PPFUSE can be used on Maxi, Mini, & ATC fuses with a maximum Amp rating of 80A. The PPFUSE calculates amp draw based on fuse size in real time. Quantify the amount of parasitic draw on your vehicle with the revolutionary PPDRAW & locate it with the all new PPFUSE! The PPFUSE is USB-C rechargeable, comes with a belt clip, replaceable tips, and a work light.
