With engine running, it is the alternator that carries the load. You need to make sure the battery has a full charge before you can do any testing. Battery connections all clean and tight? After you get it running, check the charging system. Do you have digital multimeter?

Even if the alternator is brand new, if no excite voltage, the alternator won't work.
