MAINTENANCE
Both jaws of each clamp must firmly engage the battery terminal
The wire 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 can read 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.
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.
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.
Scroll Down to Volt Meter then select
Volt Meter
by pressing 'Y'
Note: If the car is running and the
clamps are attached to the battery
a high ripple (over 50mV) indicates
bad diodes in the alternator
.
