98 Taurus Charging System Problem
Hi there, hoping some of you Ford experts can help me out. First, I was having a problem with my lights dimming and so forth, intermittently. Sometimes nice and bright all OK, then suddenly things would go a bit dim for awhile. A couple days of this, then it stopped coming back to the 'OK' and stayed dim, so I stopped and had the alternator tested. Failed at regulator, so I replaced it with a premium rebuild. It worked great for a day or so, then went back to working great for about 5 minutes then all dim again. Seems to work OK until warmed up, then *bam* things are dim again. So I thought maybe a fuse had blown. I replaced the megafuze and checked pinouts on all the relays (all OK) and all other fuses are OK. Battery was just replaced a couple months ago after the old one would no longer hold a charge. New batt hads been great, but it has run down now since this alternator issue. I am out of ideas. I suspected the battery, but the suddenness of the onset of dim lights makes me think it is not just running down gradualy...can't figure out why it is so sudden after some time running bright and great. PLEASE HELP!!!
