2002 Honda Civic EX Alternator Woes!

This is a fairly common trouble with alternators. I think the trouble you are having is due to the brushes not making contact inside the alternator. If your husband can get the belt loose and remove the alternator then replacing it should be no problem. Not too much is required for tools to do this job. If he works on it be sure to remove the negative battery cable from the battery first. The main wire to the alternator is hot to the battery. That will prevent any possible shorting problems. It would be a good idea to have the battery checked out. If it has never been changed it is time to do that also. Replacing the battery along with the alternator is a good preventative maintenance procedure. But if the battery handles a good load test then there is no reason to replace it.
