BATTERY TESTER_________________________________________________________________________
•
BAT. BAD: the battery is in bad condition and would most likely not hold enough
of a charge for reliable vehicle starting. Replace the battery.
NOTE:
A bad battery can mask other charging system problems that will be caught when
tested with a good battery. For example, a bad battery could make the diodes look bad.
SYSTEM TEST RESULTS
•
VEHICLE MAY HAVE KEY OFF DRAIN: indicates the charging system is
probably in good condition but the battery has a low charge. Suspect excessive
parasitic current drain or accessories left on during the test.
•
CHARGE BATTERY AND RETEST SYSTEM: indicates the battery either has a
low charge or is almost fully discharged and must be charged before the tester will
run any tests.
•
REPLACE BATTERY AND RETEST SYSTEM: indicates the battery is bad and
must be replaced before the tester will run any tests.
•
DIODES GOOD: indicates the rectifier diodes are good.
•
CHANGE DIODES: indicates the diode pack or alternator needs replacing.
NOTE:
To prevent an erroneous diode test, the tester does not test diodes unless the battery
condition is good.
•
CHARGING SYSTEM GOOD: indicates the charging system is in good condition.
•
CHARGING VOLTS TOO LOW/CHARGING SYSTEM NEEDS REPAIR:
indicates the charging system voltages are too low or the charging system is bad.
If the no load voltage is too low, the battery test result may be GOOD/LOW
CHARGE. This may also be the result if a heavy-power-consumption device was on
during the test. If so, the message, "Was any accessory left on" may display.
If so, check if any accessories were on, doors were open, etc. during the test.
If they were not, the test result may indicate a battery with low charge.
•
CRANKING GOOD: indicates the starting system is in good condition.
•
NO START CONDITION: indicates the battery is bad or needs recharging.
This result may also appear if the battery is too small for the vehicle, if the starter
motor is defective, or if the cranking resistance is excessive. Make sure the battery
size is correct and there are no starter or engine problems.
