Glad all is well. Before I test battery or alternator I always make sure that the connectors are clean and tight. A bad contact can leave you stranded while having a good battery and a good alternator. You get a new battery, and the new battery gets installed tight and then you swear the battery was bad. When you jump start, you bypass the loose connector. Just a thought.

 

Another test rather than taking it somewhere is to remove the positive cable from the battery while the vehicle is running. Be extra careful not to allow the terminal end to touch metal or it will ground itself out and you'll have more problems than you started with. After you remove the cable from the battery, if the vehicle keeps running....it's your battery. If it dies, then the alternator is the issue.

 

First, always remove the battery ground cable first.
Second, never disconnect the battery from the circuit on an alternator equipped vehicle. It's a good way to fry your alternator.
That is fine to do on generator equipped engines only.
