Towncar weird

[p71 JD]

Hey guys. My 99 TC started to act up today. First thing as I was driving slow to get in a complex my radio turned off,then headlights and abs lights came on. I parked it and it would not start,just the cranking sound. I jumped it for a bit and it turned on but my headlights would not turn on,windows would not roll down. I put a meter to the battery as the car was off and I got 12VTs DC. I parked the car and the lights where really dim and would flash so I disconnected the battery..I think my battery could be bad(2 yrs old) and wont keep a charge,or could it be the alternator?? I would love the pros feedback !! Thanks!!

Hello, Is the engine light on? If so whats are the codes? Sounds like the ECM is not working correctly.

Well problem is fixed. I went to Sears and bought a Diehard Gold battery.. I got home and installed it,car started up fine,I disconnected one lead off the battery,car turned off,bad alternator. I should have that tried that last night but I had forgotten that little trick. Oh well at least I have a great new battery. I called my mechanic,he was here quickly. He bought a new alternator and installed it,took him about 1/2 hour. Total cost of my adventure 130 for the battery and 240 for the alternator with install,so 370.00 for everything. This year I have spent well over 2500 for new tires and repairs,I hope thats it for a while. I know the car is a 99 and its starting to wear but i really take care of it and has exactly 100 k miles on it,and I dont want to get a new car the way our nice economy is right now,but I really like the 03 and newer town car models...
