So, I have a 97 Taurus wagon that has around 221,000 miles on it. Recently it has been having odd electrical issues...for instance, when the car is off but has the key ignition on/radio on for more than 10 minutes, the car will not start, turn over and makes clicking noises and the dashboard goes crazy. I had the battery and alternator tested a few months ago at Autozone, which they told me everything was running fine and strong. Today on my way home from work, the car randomly died while driving. First, the RPM gauge went weird and fluctuated between 0-2RPM's (the gauge was just bouncing around), then all the electricity died and the wheel locked up but the engine was still running. I managed to pull into a restaurant parking lot and it died completely. I had my sister come help jump it, and it ran until I started to drive around, and it died again. We attempted to drive it back to her house, after jumping it 4 times and making it across the street to another parking lot. Could it be the alternator or another issue? I am not very good with cars, i'm only a 22 year old female....I also am on a very tight budget....please help as to what it could be before I have to have it towed, ect....
