Inspecting the Battery
Before starting the test visually inspect the battery for:
•
Cracked, buckled, or leaking case. If you see any of these
defects, replace the battery.
•
Corroded, loose, or damaged cables and connections. Re-
pair or replace them as needed.
•
Corrosion on the battery terminals, and dirt or acid on the
case top. Clean the case and terminals using a wire brush
and a mixture of water and baking soda.
•
Low electrolyte level. If the electrolyte level is low, add dis-
tilled water to fill up to 1/2 above the top of the plates and
fully charge the battery. Do not overfill.
•
Corroded or loose battery tray and hold-down fixture.
Tighten or replace as needed.
Testing Out-of-Vehicle (Battery Test)
The preferred battery test location is in the vehicle. However, if
you plan to test out of the vehicle:
•
Always disconnect the negative cable from the battery
first and reconnect it last.
•
Always use a carry tool or strap to lift and transport the
battery.
Failure to properly install lead terminal
adapters, or using adapters that are dirty
or worn, may cause false test results.
When testing side-post or Group 31 batteries,
always use lead terminal adapters provided with the
GR8—do not test at the battery’s steel bolts. To avoid
damage, never use a wrench to tighten the adapters
more than
¼
turn.
Connecting to the Battery
Connect the testing clamps to the battery in accordance with
all precautions and safety instructions.
Connect the red clamp to the positive (+) terminal and the
black clamp to the negative (–) terminal.
If you connect the clamps in the wrong polarity (red to
negative or black to positive), the analyzer sounds an alarm
and displays CLAMPS REVERSED! Reverse the clamps and
reconnect the clamps to the battery.
To make sure both sides of the clamps are gripping the
terminals, rock the each clamp back and forth. A poor
connection will prevent testing, and the analyzer will display
the message CHECK CONNECTION. If the message reappears
after you have correctly reconnected the clamps, clean the
terminals and reconnect..
