Lights
Q) All 4 of my lights are not working.
• A) First check circuit breaker:
Set in the ON position (which is UP). Breaker should be showing red which means
◦
the system is hot.
• B) Check Toggle Switch position:
◦ Toggle switch needs to be in the correct position for which component you are trying
to use either Timer or photo cell. Refer to Label above the toggle switch for correct
positioning.
• C) Check the Battery Voltage of the unit:
• IF Below 23.5 Volts:
To do this, use a multimeter and place it on the main connection for the positive. This
◦
will be one of the parallel connections on the batteries and the other lead should be on
the main negative parallel connection.
▪ If the Battery voltage is close or at the LVD set point (23 - 24.5volts)
• The Unit has a LVD which will disconnect the lights if the battery voltage
goes below the set point.
• Units LVD set at 23.5 volts:
◦ Trick turn off breaker for the lights, this will reset LVD, this allows you to
see if the lights work, if not pasted the set point.
• Then this would be the reason why your unit's lights aren't working. You will
need to charge the unit back up. Either using solar, a/c charger or generator, if
possible or equipped with one.
• You will need to get the resting voltage of the unit above 25.5 volts before the
lights will be able to be turned back on.
• IF battery voltage is above the 23.5v fellow the steps below:
• D) Check the connections:
◦ Check the J-Box which is located between the lights. Make sure all connections are
free for corrosion and making a clean connection.
• E) Check if you have continuity:
