Load was sent back to the ups form transformer.

You should measure AC voltage from the output of the transformer to the bridge rectifier, and after the rectifier you should see a DC voltage (you may also read some "ripple" AC voltage on the DC side as well). Check across each battery to see how many volts DC they are receiving (as they will all be in series connection ie one after the other). Batteries are the usual problem with faulty UPS's. You may have a problem battery or multiple problem batteries and they may need replacing.

Hi,
After you replaced the batteries did you perform a manual battery test?
If not do so.
