There are no LEDs ON at all…
This indicates that there is no battery connected to the output (BROWN wire) or that battery is not at a
suitable voltage level to be charged
AND
the input (YELLOW/RED wire) of the charger is not connected.
1. Check the Auxiliary battery is above 4.2V
2. Check all wiring to the charger and battery, particularly the Ground (BLACK wire).
3. Check fuses are intact and properly connected.
If the problem is still evident please contact your local Auto-Electrician.
The ‘Charge Profi le’ LED is fl ashing…
This indicates that either Output or Input is not valid.
Specifi cally, an Auxiliary battery, at a suitable voltage level to be charged, is connected to the output of
the charger however there is currently no valid charging source
OR
a valid charging source is available
but the Auxiliary battery is not at a suitable voltage level to be charged or is not connected.
1. Check that the Vehicle (RED wire) and/or Solar (YELLOW wire) are electrically connected
1. The Vehicle (RED wire) should connect directly to the Vehicle battery positive terminal via an
adequately rated fuse
2. The Solar (YELLOW wire) should connect directly to the Solar Panel positive terminal/wire.
2. Check that the Ground (BLACK wire) is connected to the Auxiliary battery and Chassis Earth and/
or the Solar Panel negative terminal/wire.
3. Check the Auxiliary battery is above 4.2V
4. Check all wiring to the Auxiliary battery, particularly the Ground (BLACK wire).
5. Check fuses are intact and properly connected.
If the problem is still evident please see the relevant points below.
I have Solar connected but the ‘Solar’ LED is OFF…
This indicates that the required turn ON conditions for this source have not been met. Either the Open
Circuit Voltage at the YELLOW wire on the charger is below 9V or there is not suffi cient power available
from the Solar Panel (due to poor light conditions or a faulty panel).
1. Is the sun out? No or low sunlight levels mean low power to your solar panels.
2. Check that the solar panel is not being shaded (by a tree etc.)
3. Check the voltage at the YELLOW wire, as close as possible to the charger, is above 9V.
4. Check all wiring to the Solar Panel, particularly the Ground (BLACK wire).
Allow up to 2 minutes after any change for the unit to recognise the input, if the problem is still evident
please contact your local Auto-Electrician.
The BCDC is connected to the ‘Vehicle’ but the Vehicle LED is OFF…
This indicates that the required turn ON conditions for this source have not been met
OR
the Solar input
is supplying the full input power requirements of the charger. With the BLUE wire left unconnected, the
voltage at the RED wire must be above 13.2V for a 12V installation or above 26.4V for a 24V installation.
With the BLUE wire connected to Ignition, Ignition must be on and the voltage at the RED wire must be
above 12.0V for a 12V installation or above 24.0V for a 24V installation.
1. Check that the vehicle is running.
2. Check the voltage on the RED wire is above the required turn ON threshold for your installation.
(See section 1.4 on page 6)
3. Check all wiring to the Vehicle battery, particularly the Ground (BLACK wire).
If the problem is still evident please contact your local Auto-Electrician.
