CLAMP MAINTENANCE
:
Both jaws of each
clamp must firmly
engage the battery
terminal. The wire
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL INSULATOR
Over time the battery clamps will need to be replaced if any of the
following are indicated:
CCA values seem extreme.
If there is continuity between the copper insert and the clamps.
If there is excessive damage or corrosion to the cables or
clamps.
CLAMP and BATTERY REPLACEMENT
Remove the screws from the back cover.
Separate top and bottom cover and open like a book leaving the
ribbon in contact with the PC board that will remain with the back
cover.
CLAMPS:
Remove the cables and strain relief. With the new
load clamp leads pointing down; insert the new strain relief into
the back cover. Make sure the red clamp wires are attached to
the left two screws of the green screw terminal (labeled POS)
and the black clamp wires are connected to the right two screws
(labeled NEG). It does not matter if either of the two red clamp
wires is switched. The same applies to the two black clamp
wires. Just make sure the red clamp wires are to the left (POS)
and the black clamp wires are to the right. (NEG)
BATTERY:
Remove the battery and replace with a 9 Volt battery.
Match the (+) on the new battery with the (+) on the PC board.
Reverse the procedure to assemble the unit.
soldered to the copper insert jaw must be insulated from the
other wire soldered to the opposite handle. This insulation is
required so than one can read the Amps and the other reads the
Volts. Damaged clamps or loose wires will affect readings. Make
sure the copper jaw insert is properly insulated from the clamp
and the clamps are clean and in good repair.
