When the UPS is plugged into the wall socket with no load the green and amber lights flash steady. Nothing else. UPS never goes to solid green. I have checked the house voltage and hertz with quality testing equipment and have the following results. Voltage on each phase of power is between 126 volts to 127 volts. Much higher then normal. I am going to call the power company on Monday in regards to this. Hertz are a solid 60 Hz no fluctuation. The 126 or 127 volts should still be with in the range for this unit even though this is high. I have also done a brain dead restart also. No change. This is also the original battery for this unit. At least 6 years old. I cannot get the enter the programming mode to try and change the sensitivity. Any thoughts?

Can you provide the exact model number and serial number of the UPS? If you cannot post it here you can send it to me via PM.
