RV Repair: Battery, happy camping, electricty

Question
After leaving my electric campsite, I stopped to dump.  I always go innside and run the water with the pump to rinse things.  This time, when I turned on the pump, I got a load beep and then all the battery power went off.  I checked all the fuses and they were fine.  When I got it home I plugged it in and the house electricty worked fine and I then had power again.  Is this the sign of a bad battery or is there another problem.  The Camper is only 1.5 years old.

Answer
Kerry,
     I would first check the water level in your coach battery and if it's full I would have it charged and load tested.  If it's not full, fill each cell with distilled water and charge and test.  I would also check the charging output at the battery to make sure it is correct as well.  I hope this helps, good luck and happy camping.
