TEST
NOTE
The alternator belt must be properly adjusted before alternator testing may be per-
formed.
1.
Start the starboard propulsion engine and run it at 1500 r/min.
2.
Place a load on the 24 Vdc (Volts direct current) electrical system by turning ON as many 24 Vdc systems as practical.
3.
Set the multimeter to the Vdc (Volts direct current) setting.
4.
Place the negative (-) multimeter lead on the negative output terminal (6) and place the positive (+) multimeter lead on the
positive output terminal (7).
5.
Observe the multimeter reading. A properly operating alternator should produce 26 to 29 Vdc. If the reading is outside
this range, notify unit maintenance for troubleshooting and/or replacement.
6.
Repeat steps 1-5 for the port alternator.
