2.15.
ALTERNATOR/CHARGING CIRCUIT DIAGNOSTI(
Perform alternator and charging system test whenever a
low voltage output is indicated at the gauge panel, or if
you are sent here by another diagnostic test.
Stay alert when performing alternator and charging
circuit tests. Some tests are performed on live electrical
circuits and can present a severe shock or burn hazard.
Some of the voltage checks are performed under high
current conditions. Be very careful when performing
these tests.
If you have engine starting difficulties (slow or no engine
cranking), you should refer directly to paragraph 2.17 for
battery circuit diagnostics. Battery circuit diagnostics will
refer you here only after the battery circuit is checked
and found to be good.
