What is your question?
In early March, I had a check engine light come on in my 2005 Ford Focus. I had code checked and they told it would go off by itself. I disconnected battery to make light go off sooner and ever since I have electrical issues, the common ones being my transmission having shifting issues and my clock and radio resetting every now and then. I just learned about the connection between these issues and the battery today (early May). Now that I know the problem, what can I do to fix it?

Owner: We would begin by testing the Alternator operation, to confirm clean ( no ac ), charging system voltage.
The code was a P0128
