TROUBLE SHOOTING
If the display flashes or shows one flashing letter, the battery is too low
(< 8 volts) to test. Fully charge the battery and retest.
A conn message that alternates between bAd and CELL means one or more
battery cells are bad. Replace the battery.
A conn message means there is a bad connection. Disconnect the clamps and
reconnect. Make sure to rock the clamps back and forth to make a
good connection.
If the top-panel red LED lights when you test in-vehicle, there may be a poor
connection between the battery cables and retest at the battery posts before
replacing the battery.
Excessive electromagnetic interference may cause the tester to reset during
testing. Before retesting, reconnect the clamps and:
•
Make sure all vehicle loads and the ignition are off.
•
Move away from the noise source, which may be a charger or other
high-current device.
•
If you are unable to find the noise source, fully charge the battery and
retest at the battery posts. If the top-panel red LED lights again, replace
the battery.
