Been having a intermittent battery drain on a 1991 Ranger, and I think I found what's causing it. There is the "green" relay (fuel pump), a "brown" relay (EEC), and a "black" relay on the passenger side fender well. I noticed with the key off the "black" relay was pretty warm so I bumped the fender hard, and heard a click, after a while it cooled off. What does the "black" relay do?
