Here is the alternator that is apparently not charging. First thing is to test it to make sure it is the problem.
B+ is the post where one can test the output voltage of the alternator with a simple multimeter.
Set the multimeter to 50 DC Volt scale. Black probe to ground and red probe to B+ on the alternator. With the engine running the voltmeter should show around 14 Volts. On this alternator the voltage does not increase and sits somewhere around 10 Volts. Good indication that it needs to be changed.
