You need to measure the battery voltage using a digital voltmeter across the battery with the engine idling and all accessories off.
You should see between 13.5v and 14.8v. If you don't, there is a problem with the charging system.

That wasn't a fix. I'm just trying to determine if the charging system is working or not. I suspect it is not so we will have to do further testing to determine why.
