Yesterday I tried to start my XJ and the battery was nearly dead. It was a miracle that I even got it to start. The check engine light was on, so I pulled the codes. I got a fault code 41, which is bad/faulty/incorrect switching.....I'm assuming the alternator isn't switching correctly.
Funny thing is the problem didn't come back after I drove around. This makes me wonder is there's an intermittent short somewhere causing my battery to drain and storing the fault code 41. Has anyone ever had this code? Is it possible the alternator is intermittently bad? I'd think an alternator is either bad or good, but not having problem intermittently. Any help is appreciated.
