"Charging System Failure" ??
2005 Montana SV6; 155,000 miles; I finally replaced the factory alternator. The headlights have flickered since new, but it always kept the battery charged and there were no indicator lights illuminated. I put in the alternator and now everything seems fine (except the "Charging System Failure" message comes up and the battery light is on). With it running, I am getting 13.6 volts, it drives fine and is keeping the battery charged. I compared the old alternator to the remanufactured one before turning it in and they were identical. As you probably know, it is a real PAIN to swap out the alternators - what a pathetic design!
Should I worry about this problem or should I just drive the van until it wears out? ideas?
