I had a similar problem on my Fiesta before Woodburn. I ended up splitting the pack and see which side was still leaking to chassis.
The first thing I did was find the low point on the pack. You have two of them. I used a 60 watt 120 VAC light bulb for a test light and started working both ways from the low spot. I then split the pack two batteries away from the apparent problem and re ran the test. The problem was then obvious. One of my terminal covers had been pinched enough to cause some leakage but not enough to show a short with the meter. Once this was located and repaired, I found some other crud on a wire leaking to ground. Once this was cleaned up, I could connect the light bulb from any point on the pack and it would not light. The meter showed a capacitor discharging when I ran a voltage check on all the points.
