15. MAINTENANCE INSTRUCTIONS
The charger is designed and built with high quality materials requiring only a minimum amount of care:
1.1 Clamps should be cleaned each time the charger is used to prevent corrosion from battery uid.
15.2 Cords should be coiled when the charger is not being used to prevent damage.
1. Other servicing should be performed by qualied service personnel.
16. TROUBLESHOOTING
16.1 No amperage reading while charging a known good battery (voltage will still show):
a. Check AC outlet to be sure it is live.
b. Check connections to battery.
c. A circuit breaker may have opened. Refer to Section 9.5.
d. Ensure that all operating instructions were followed.
16.2 Certain battery conditions can cause meter to indicate incorrectly—including cold, sulphated,
or damaged batteries.
16.3 A Starter or Alternator test appears to fail. Conrm that the charger was left unplugged for
the entire duration of these tests. If charger is left unattended while running a Starter or Alternator
test and someone should happen to plug it in, the test will automatically be disabled and results
will not be valid.
16.4 Display panel blanks out after a test. This may happen if the 15-minute test has been allowed
to run unattended for more than 20 minutes or so, and indicates the battery was either
1) not able to accept a charge and is probably BAD, or
2) was completely discharged.
Repeat the battery test, and be there to monitor results when timer shuts off at 15 minutes. If
battery still shows FAIL and/or the display shuts down again after several seconds, then the
battery cannot even hold enough power to run the monitor display. It is likely unable to accept a
charge and should be considered BAD. See Section 8.1.
