flashing LED error code.

LEDs do not light:
1) If boat is off plane or stopped for several minutes, the ALC display enters a normal power off mode to
prevent discharging the battery. Operating the boat and pressing the display buttons will bring the display
back to fully operational mode.
2) If optional terminal 7 (green plug) is used and connected to the ignition key switch, turn key switch to ON
and make sure battery selector switch is turned on.
3) Measure voltage at terminal 1 (green plug) (+12 or +24vdc) and terminal 2 (battery negative) for proper
voltage (see wiring diagram). Replace fuse or repair poor connection if battery voltage is not measured at
terminals 1 and 2.
