Electrical Help Please

Do you have a voltmeter in the car? If not put a voltmeter on battery with car running to check output of alternator should be at least 13 volts or more when at fast idle, about 1000 RPM. If you don't have a voltmeter, get one to do any electrical troubleshooting. Harbor Freight has one for about $5. Maybe even an Auto store as Advance auto or auto zone can check charging system for you.
I have the stock AMP meter in the car. It is moving from straight up to far right at times and middle right while I drive. The electric fan came on at Auto Zone. Stayed on for a few minutes with the car not running while I was there. When I restarted the car it was slow to start..... but it started. Then the AMP meter in the dash swung all the way to the right like it was charging............
