to test output voltage.
Disconnect and reconnect the 12V
connections.
Use a true RMS reading meter.
Red LED is lit.
The battery voltage is below
10 volts.
The equipment being operated is
drawing too much power.
The inverter is too hot (thermal
shutdown).
Recharge or replace the battery.
Use a higher capacity inverter or
decrease the load or device on the
inverter
Allow inverter to cool. Check for

load on the inverter to the rated
continuous power output.
Alarm sounds
continuously.
Input voltage is below 10 volts.
