i have a 93 el dorado with a charging system problem.the car completly loses all power. ive changed the alternator in oct. of last yr. it seemed to cure the problem the it started again. it says “battery no charge”. so i changed the battery and the problem went away for a few days and then started again. so i changed batttery cables and the problem went away for a little while and now its not charging again. if anyone can help me figure out what the problem is,i would appreciate it.
It sounds to me like you are hitting around the real problem. I’m guessing a loose or dirty ground strap connection somewhere that gets moved when you change out the battery, alternator, etc. and then eventually loses contact again. That’s what I’d be looking for, but it is just a guess.
