The "Keep alive memory" in the PCM will draw about 15 milliamps which is enough to light a test light. Putting an ohm meter across the battery cables with the battery unhooked won't tell you anything as you will be measuring resistance across the PCM, FICM, and IPC not to mention other modules. You can use a digital ammeter in between one battery cable and terminal and measure the current draw. It may take up to 30 minutes for all modules to go to "sleep mode". If it gets down to about 15 milliamps, that's normal. Wash off the tops of the batteries. If there is much acid/water on the top of the battery(s) current will flow through it and drain them.
