You don't say what the "problem" is, or what has changed. You don't say how your ammeter shunt is wired into your system, and what it's measuring - is it:

• Alternator output
• Bus current usage
• Battery in/out current

Until all of these questions are answered, there's no way to know if there even IS a problem, much less what it is and how to fix it.
