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.
GATOR CLAMPS
TM
Both jaws of each clamp must
firmly engage the battery
terminal. One copper jaw
contains the smaller gauge wire
that reads the voltage and the
other jaw connects to the larger
conducting wire that draws the
load in each test. Electrical
insulation between jaws is
necessary for accurate readings.
For side terminal battery
connection, the threaded stud
connects to the smaller gauge
wire that reads the voltage, and
the load pad ring connects to
the larger conduction wire that
draws the load in each test.
Damaged clamps or loose wires
will affect the readings. Keep
clamps clean and in good repair.
Store clamps on posts as shown.
