One thing you want to check is if the erratic warning light behavior disappears with a fully charged battery. Put it on a trickle charger overnight and then drive to see if the issue is gone; if so, then you probably are in fact looking at a bad ground issue. My issue would go away when I charged the battery, then it would slowly return over a few hours of driving and I would occasionally have to jump start due to low battery.
