DiagnosticLEDs
The Load Control Board (LCB) is equipped with three diagnostic LEOs. These LEOs provide indications of the operating status
of the LCB and the alternator.
The LCB diagnostic LEOs function as follows:
LED
FUNCTION
D2 This Led provides a steady series of flashes, at 20-per-second, indicating communication between the
LCB and the display panel is functional. If this LED is off or flashes erratically, replacement of the LCB,
the display panel or the communication cable may be required.
D3 This LED provides a steady series of flashes, at one-per-second, indicating the LCB microprocessor is
functional and the loop circuit is operating. If this LED is off or flashes erratically, replacement of the LCB
may be required.
D13 This LED is normally off. If alternator output voltage exceeds 19 volts, the LED lights steady on. This con-
dition will also cause the "Needs Service" message to display (see Display Maintenance Mode for details).
NOTE: The diagnostic LEOs provide
a
general indication of certain equipment malfunctions. Refer to Section 4,
Troubleshooting to aid in locating the most likely cause of the problem.
