Operating Instructions

Read the ENTIRE IMPORTANT
SAFETY INFORMATION section at the
beginning of this manual including
all text under subheadings therein
before set up or use of this product.
General Operating Instructions
1. Remove the protective tip from the Probe
(1). Be careful, the tip is sharp.
Note: Before each use, first test the Circuit
Tester on a known, working 6V or 12V source
so you are sure it is in proper working order.
2. To test 6 volt or 12 volt fuses, wiring, or other
6V/12V circuitry, connect the Cord Clamp (11)
to one side/end of the fuse, wire, vehicle battery
post, etc. (either positive or negative pole).
3. Gently touch and hold the tip of the Probe (1) against
the other side/end of the object being tested.
4. If the Bulb (3) inside the Handle (2) illuminates,
this indicates there is electricity flowing through
the circuit. No illumination of the Bulb indicates no
electricity flowing through the circuit and that repair
or replacement of the object being tested is needed.
5. When finished using the Circuit Tester, replace
the protective tip and store the tool in a clean,
dry, safe location out or reach of children.
