08 Ford Taurus Check Charging System

Asked by Ron Dec 22, 2018 at 10:12 AM about the 2008 Ford Taurus SEL

Question type: Maintenance & Repair

I've recently replaced the alternator and battery in
my car and the battery light continues to come on
and stay on. A mechanic told me that the new
alternator could be bad also but not for certain.

If your battery light is on, and it's not the alternator or the battery, Then you will have to go through these steps. It's either a break in an orange/blue wire coming from the connector that connects to the alternator regulator, which runs to the ECM, or you need a new ECM. Mine was the ECM. Good Luck!
