I just figured this out by reading THIS, but I inadvertently fixed the issue when I unplugged the ABS unit because it was pumping air into the brake lines and leaking.
At approximately 190000 miles my 1994 Subaru Legacy 2.2L Sedan began "eating" batteries and then alternators. This resulted in about four warranty replacements of each over a period of four years.
