Testing Out-of-Vehicle

The preferred battery test location is In-Vehicle. However, for testing Out-Of-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.

Testing In-Vehicle

The preferred test position is at the battery posts. If you must test at a remote-post location, it
should have both a positive and negative post. Otherwise, you must remove the battery and
perform an out-of-vehicle test.
At the start of the test, make sure all vehicle accessory loads are off, the key is not in the ignition,
and the doors are closed.
Connecting To A Battery
Connect the clamps to the tester: the red clamp to the positive (+) terminal and the black clamp to
the negative (–) terminal. If the clamps are reversed when connected, the tester displays CLAMPS
REVERSED! Reconnect the clamps.
Make sure both sides of the clamps are gripping the terminals by rocking each clamp back and
forth. A poor connection will prevent testing, and the tester will display a CHECK CONNECTION
message. If the message reappears after reconnecting, clean the terminals and reconnect.

Setting User Preferences

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 tester—do not
test at the battery's steel bolts. To avoid damage, never use
a wrench to tighten the adapters more than ¼ turn.
Do not connect the tester to a voltage source
greater than 30 Vdc.
