Not sure how much of this might be related.
Several months ago, I noticed that my headlights would occasionally flicker at highway speeds. Since it was just a minor annoyance, I ignored it.
My (original, 9-yr-old, 90K mile!) battery died about a month ago and I replaced it. All was fine (except for the same flickering headlights) until yesterday, when my console battery light started flickering...constantly. I planned to take my car to AutoZone to get the computer checked, but before I could get there, I'm driving 45 mph when the speedometer drops to 0, my low fuel and airbag console lights come on, my headlights and interior lights go almost completely out, and the car starts lurching. (Scary!)
I just barely managed to get it home, where it's now parked. Before I buy a new alternator, does it sound like I just need to replace the alternator, or might it be something else?
(The car is a 1999 Ford Escort SE.)Lights and speedometer go crazy after battery change?It's the alternator. The diode pack fried. When one of the diodes went, it gave you the flickering lights. When the rest went, your dc electrical system tried to run on ac. Lights and speedometer go crazy after battery change?check your battery terminals. make sure they are clean and tight.Lights and speedometer go crazy after battery change?Sounds like a problem in your motherboard. Ford is notorious for faulty computer problems.
