The ground cable being cracked would not cause that problem.before repairing or changeing your alternator, check the chargeing gauge for malfunction.If your alternator is bad, the battery light would come up on the dash board.

If you have concerns with the alternator, go to our home page and under the do it yourself section, it describes how to check the alt. Also, keep in mind you have fuseable links between the alt and battery. One may be going bad and not always allowing the alt to do its job.
