MAINTENANCE
IMPORTANT:
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.
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
BATTERY CLAMP 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 silver and copper jaw.
If there is excessive damage or corrosion to the cables or
clamps.
PROCEDURE
Disconnect the back cover.
Disconnect the two small wires from the PCB.
Remove the large cables from the copper busses.
Carefully pull each wire through the grommets.
Reverse the procedure when installing new clamps.
Caution
: With cables pointing down, make sure the red clamp
wires are attached to the left buss and the black clamp is attached
to the right buss. Putting a little mineral spirits on the new cable
ends will help with ease of insertion through the grommets.
BATTERY REPLACEMENT
When the LCD indicates a low internal battery remove the back cover
and replace the battery with a 9 volt Alkaline battery.
VOLT METER
Unusual problems with a battery and the need to localize loss of current
can be determined with the manual volt reading.
From the Other Menu select
Volt Meter
.
Press (Y Enter)
The following will be displayed.
Note: If the car is running and
the clamps are attached to the
battery a high ripple (over 50.0
mv) indicates bad diodes in the
alternator
.
SETUP
From the main menu select OTHER the ABOUT for the second menu.
Select the temperature in
Fahrenheit or Centigrade.
Select the rating from JIS,
DIN, IEC, EN, CA, MCA, CCA
or NONE. If none is selected,
each time a battery test is per-
formed the unit will prompt for
the battery rating.
