1990 Ford Festiva won't keep running once warm, idles rough and stops drawing off alternator
car will fire up no problem and run half-decently on battery alone until battery is drawn to almost dead. alternator seems to be fine, was replaced.
Confirm alternator is pushing power to the battery, do you have a battery gauge or voltmeter. See if there a voltage increase after it is running should be in the 14+volt range or just remove it, take to parts store, have load tested and battery too. Make sure all Terminal cables & terminal ends are good and no corrosion, check engine to frame grounds. & all fuses under hood and dash.
I'll give these a try and go from there. thank you for the advice. hope to get at it this weekend.
