Typically it means you should start saving for a new alternator. One of the not so rare engineering flaws on this generation Cougar is the alternator, which will die due to poor factory wiring fairly often. There are mods to fix this problem, and Ford Lincoln Mercury dealers will see instructions to change the wiring of the alternator to be like that of the '01 and '02 Cougar2s when they go to change the Alt, not all alternator shops will necessarily know this is an issue.

If you take this on yourself, know this, the after market (ie motocraft) alternators for the Cougar are not nearly as reliable as the genuine Ford OEM product. And also, even if you take the alternator to have it checked at pep-boys or such, it will probably show that it is still good while it is indeed the issue.

This happened to me on a road trip in my 84 Cougar. It was a long time ago, but first make sure your belts are tight! But I believe you may need to replace the alternator. If the battery is old, its cheap insurance to do both.
