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 ll up to 1/2 above the top of the plates and
fully charge the battery. Do not overll.
• Corroded or loose battery tray and hold-down xture.
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
rst 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. .
