I have a 94' Escort with the 1.9 engine. The alternator/battery charging light has been coming on, but only when the engine speed reaches about 2000/rpm. It goes out when the RPM drops below 2K. The headlights dim a little when the warning light is on. They get brighter when the light goes out. This would seem to indicate that the alternator is not charging above 2K-RPM. I don't think the drive belt is slipping. There aren't any noises either. Suggestions?
Thanks
