Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Do you own a volt meter?
What brand alternator are you installing?
Since you do not have the tool we need to diagnose this. I need to confirm what it is your wanting from this conversation. Is it just an answer as to what I believe is wrong since we can not diagnose it without this tool?
There are 2 tests we need to run. A drain test to see if the battery is draining while the car is off making the alternator work to hard and check the alternator wiring through the tests below.
If you get stuck doing these tests let me know. Aftermarket alternators do not work well on this vehicle since its a PCM controlled charging system.
