Try this. NO guarantee but if it works SMILE..
Disconnect every power source.. 120 volt, turn off the breaker that feeds the beast.. 12 volt pull the fuse or lift the negative leade.. COMPLETLY shut it down (Remove all power SOURCES as well as turn the switch on the unit off)
Count to at least 10.. Slowly... Or try a cup of coffee made before shutdown.
Now reconnect power (Both types) and see what happens.
Also as I said in the other thread.
Measure battery voltage at the battery with a digital volt meter
And again at the inverter Both when you first re-connect (Shoudl be same) and watch the meter when you turn it on and note the LOWEST reading.
