do you have a multi meter on hand ?

can you see with the key ON if the big power wire at the alternator shows 12 volts ?

Ford Mechanic: Gary, Technician replied 2 years ago

ok if that big power wire shows 12 volts with the key ON on the 3 wire connector at the alternator does the orange/light blue wire terminal in the connector show 12 volts ?

Ford Mechanic: Gary, Technician replied 2 years ago

ok

Ask Your Own Ford Question
Ford Mechanic: Gary, Technician replied 2 years ago

ok with BOTH those tests showing 12 volts and 2 brand new alternators the only other thing to cause this alternator not to charge is one of the other 2 small wires in the connector being bad from the alternator to the computer being bad or have high resistance or the terminals in the connector being opened up or bad or the computer is bad

as the computer tells the alternator when to charge

the usual way this goes is inspecting the terminals if they look good if they do a visual on those 2 wires from the alternator to the computer if they look good than those 2 wires need to be ohmed out end to end to check for an open or high resistance

if those 2 wires test out good the only thing left is a bad computer i am sorry to say

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
