test again with the engine at fast idle (2,000 RPM or more.)
If Measured Output is displayed
the output may be low for some
systems.

CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
BATTERY CLAMP/LEAD REPLACEMENT
Over time the battery clamps will need to be replaced if any of the following are indicated:
CCA values seem to be way off.
If there is continuity between the copper jaws.
If there is excessive damage or corrosion to the cables or clamps.
Store clamps on posts as shown.
1. Remove protective rubber boot from tester.
3. Remove both volt lead Phillips head screws,
lock washers, and flat washers using a
Phillips screw driver.
4. Remove the 8 mm hex head bolt, lock
washer, and flat washer from the positive side
current lead using an 8 mm socket.
2. Remove battery cover on the back of the
tester by removing the 4 Phillips head screws
using a Phillips screw driver.
Both jaws of each clamp
must firmly engage the
battery terminal. The
copper jaw contains the
smaller gauge wire that
reads the voltage and
the silver jaw contains
the larger conducting
wire that draws the
load in each test. Jaw
insulation is necessary
for accurate readings.
Damaged clamps or
loose wires will affect the
readings. Keep clamps
clean and in good repair.
IMPORTANT:
High Regulation will damage
the system. High Regulation is
likely due to a faulty alternator
and/or voltage regulator.
