POSSIBLE CAUSE
Poor contact at terminals.
Using incorrect type of voltmeter
to test output voltage.
The battery voltage is below
10 volts.
The equipment being operated is
drawing too much power.
The converter is too hot (thermal
shutdown).
Input voltage is below 10.5 volts.
Poor or weak battery connection.
The converter may not have
the required capacity to operate
the device.
Disconnect and reconnect the 12V
connections.
Use a true RMS reading meter.
Recharge or replace the battery.
Use a higher capacity converter; do
not use with this equipment.
Allow converter to cool. Check for
adequate ventilation. Reduce the
load on the converter to the rated
continuous power output.
Recharge or replace the battery.
Check for poor connection to
battery. Make sure connection
points are clean.
Turn the converter switch OFF and
ON, to reset the converter.
