Battery 75 % Led On; Battery 50 % Led On - Husqvarna 967187001 Workshop Manual

13.16 Battery 75 % LED on

To activate 75 % LED, press the Battery 75 % LED
button on in the test and then the LED for 75 % in
the battery symbol will light up (rectangle second
from top of battery scale).
If it does not light up, check the cables to see if
there is a fault there. From CCU connector A:8, a
voltage signal is sent via Cable 2 to the connector
under the control panel where it is connected to
pin 3. If the LED in the 75 % symbol does not
light up, unplug the connector under the control
panel and take a reading on pin 3 in the connector
coming from Cable 2 with a multimeter set to
measure volts while activating the output via the
computer. Around 11 V on pin 3 should then be
seen if the cable is OK. If coupling the connector
to the control panel and it does not light up the
LED for 75 % even though voltage in the connector
has been checked without the control panel being
connected, it will be necessary to change the
control panel for a new one. If more LEDs than
the battery symbol come on or any in a button,
or in the triangle, it may be due to conduction in
the cable between the leads. When testing these
LEDs, only one LED at a time should be activated
so that it can clearly be seen if several light up. If
several light up at the same time, take a reading
on all pins in the connector under the control
panel to see that there is no voltage on multiple
pins going to the LEDs. Pins 2, 3, 4, 5, 6, 7, 8
and 10 are to LEDs so if only one LED at a time
is activated, there should not be a voltage on any
other the other pins leading to the LEDs. Pin 1 is
GND and pin 9 is +5 V, pins 11 and 12 are buttons
on the control panel (switches). Conclude the test
by turning off 100 % LED.

13.17 Battery 50 % LED on

To activate 50 % LED, press the Battery 50 % LED
button on in the test and then the LED for 50 % in
the battery symbol will light up (rectangle second
from bottom of battery scale).
If it does not light up, check the cables to see if
there is a fault there. From CCU connector A:9, a
voltage signal is sent via Cable 2 to the connector
under the control panel where it is connected to
pin 4. If the LED in the 50 % symbol does not
light up, unplug the connector under the control
panel and take a reading on pin 4 in the connector
coming from Cable 2 with a multimeter set to
measure volts while activating the output via the
computer. Around 11 V on pin 4 should then be
seen if the cable is OK. If coupling the connector to
the control panel and it does not light up the LED
for 50 % even though voltage in the connector
has been checked without the control panel being
connected, it will be necessary to change the
control panel for a new one. If more LEDs than
the battery symbol come on or any in a button,
or in the triangle, it may be due to conduction in
the cable between the leads. When testing these
LEDs, only one LED at a time should be activated
so that it can clearly be seen if several light up. If
several light up at the same time, take a reading
on all pins in the connector under the control
panel to see that there is no voltage on multiple
pins going to the LEDs. Pins 2, 3, 4, 5, 6, 7, 8
and 10 are to LEDs so if only one LED at a time
is activated, there should not be a voltage on any
other the other pins leading to the LEDs. Pin 1 is
GND and pin 9 is +5 V, pins 11 and 12 are buttons
on the control panel (switches). Conclude the test
by turning off 100 % LED.
