There is a 160 milliamp current flow through the Central Junction Box fuse #15 with everything off - draining both batteries after several days of not running the truck. I have had Auto Zone test the batteries and the charging system; all OK.

This fuse feeds: Stop Lamp Switch, Gereric Electronic Module (GEM), Powertrain Control Module (PCM), Four Whel Anti-lock Brake System (4wABS), Brake Shift Interlock, and Cluster and PCM Keep Alive Memory.

Anyone know what the normal current flow should be, and what would be the best method for isolating which of the controls/modules is causing excessive drain (assuming 160 mA is excessive)?

If I disconnect the GEM in this process, does it have to be re-set/re-programmed?
