INTRODUCTION
Thank you for purchasing Power Probe products. The Power Probe is the best professional elec-
trical tester for reducing diagnostic time in 6 to 24 volt automotive electrical systems. After a 
simple hook-up of the Power Probe to the vehicle’s battery, the automotive technician can deter-
mine at a glance at the red/green LED indicator, if a circuit is positive, negative or open without 
reconnecting hook-up clips from one battery pole to the other. The Power Probe switch allows 
the automotive technician to conduct a positive or negative battery current to the tip for testing 
the function of electrical components without the use of jumper wires. And yes, it is short-circuit 
protected. It tests for bad ground contacts instantly without performing voltage drop tests. It al-
lows you to follow and locate short circuits without wasting precious fuses. The Power Probe 
can also test for continuity with the assistance of its auxiliary ground lead. With a fl ip of the 
power switch, you will know at a glance that your Power Probe is functioning without running 
to the battery as you would otherwise have to do with simple test lights. The Power Probe’s long 
cable allows you to test along the entire length of the vehicle without constantly searching for 
ground hook-ups. If you are not using the Power Probe now in your electrical testing, you are 
spending too much diagnosic time.
Before using the Power Probe please read the instruction book carefully.
Warning!
When the Power Probe’s switch is depressed battery current is conducted directly to the tip 
which may cause sparks when contacting ground or certain circuits. Therefore the Power 
Probe should NOT be used around fl ammables such as gasoline or its vapors. The spark of 
an energized Power Probe could ignite these vapors. Use the same caution as you would when 
using an arc welder.
The Power Probe I & II and the ECT 2000 are NOT to be used with 110/220-volt house cur-
rent, it is only for use with 6-24-volt systems.
