8. TROUBLESHOOTING AND FAQ
If yellow LED flashes once the push button is pressed
and hold, the LE itself is fine. However, there is some
problem in the operation of the LE, which is linked to
either of the following events: the connection to the
lead acid battery is not working (tripped fuse or bad/
no connection to lead acid battery or wrong polarity); short circuit.
Please check if the LE is properly connected to the lead acid battery with the
right polarity and if the lead acid battery voltage is higher than 10.5 V. Also, ple-
ase check if the 20 A fuse at the LE and any other fuse in the line between the LE
and the lead acid battery is tripped. Exchange tripped fuses and recheck status
once it is assured that connection to lead acid battery is done properly (no short
circuit, right polarity, properly connection at lead acid and LE). Once the issue is
resolved, restart the LE by pushing the push button.
