## Discrepancy

DURING A POST FLIGHT INSPECTION CHECK, DISCOVERED THAT THE POSITIVE TERMINAL ON THE APU BATTERY HAD ARCING DAMAGE. THE DAMAGE WAS ALSO NOTED ON THE CONNECTOR.  AN INVESTIGATION CONCLUDED THAT IT WAS POSSIBLE THE FLIGHT CREW HAD NOT CORRECTLY ENGAGED THE CONNECTOR FULLY AND CAUSED ARCING OF THE CONNECTOR. A NEW CONNECTOR WAS INSTALLED ALONG WITH AN OVERHAULED BATTERY. THE AIRCRAFT WAS RETURNED TO SERVICE.
