Connect both clamps to the battery terminals.
One or both clamps are not making proper contact
with the battery terminals. The tester requires that
both sides of each clamp be firmly connected before
testing.
√
For a proper connection, rock the clamps back
and forth. If the message reappears, clean the
terminals and reconnect the clamps.
√
You are conducting an out-of-vehicle test on a
non-12-volt battery or batteries connected in se-
ries. Disconnect the batteries and test them indi-
vidually.
The clamps are connected in the wrong polarity:
positive to negative or negative to positive.
The battery will hold a surface charge if the engine
has been running or after the battery has been
charged. The tester may prompt you to remove the
surface charge before it begins testing.
√
Follow the tester's instructions indicating when
to turn the headlights on and off. The tester will
resume testing after it detects that the surface
charge is removed.
The tester has detected computer, ignition noise, or
parasitic drain, and will attempt to retest. Make sure
all vehicle loads are off, the doors are closed, and the
ignition is in the off position. The tester automatically
retests when it no longer detects system noise. If the
message reappears:
√
Disconnect the clamps and retest.
√
You may be testing too close to a noise source,
such as a charger or other high-current device.
If so, move away and retest.
