√ If you are unable to find the source of the noise,
fully charge the battery and retest. If the message
appears after recharging, test the battery out of
the vehicle.
√ A battery that is weak, or that has just been
charged, may retain enough electrical activity to
for the tester to detect and will adversely affect
the test results. A fully charged battery should sta-
bilize quickly, after which the tester will automati-
cally retest. Weak batteries should be charged
and retested. If the battery is fully charged, check
the clamp connections.

CLAMPS
The clamps are not making good contact with the
