Good afternoon,

Never ever take a battery cable off while the engine is running. It tests nothing and you can damage modules from voltage surges.

The first thing you need to do is have the battery load tested to be sure it is good. Then the charging system needs to be checked to verify the proper voltage to the battery to maintain the charge. You need 14 to 14.5 volts from the alternator.
