#15 Fuse Causing draw. NEED HELP
Good afternoon wise ones of the FTE forum. I am seeking help with my baby, she is a 2001 F350 Super Duty CC 4X4. I have a power draw on the batteries of .246 amps. I have gone nuts tracking it down, from cables, to alarm, to disconnecting both alternators one at a time to fuse by fuse check. FINALLY I found a .246 amp draw on fuse #15. Pull this fuse the draw drops to an acceptable .055-.056.. I went to the owners manual and looked up the #15 fuse and just my luck there are several BIG items in the list: Stop Lamp Switch (Logic):Generic Electrical Module (GEM), Powertrain Control Module (PCM), Four Wheel Anti-Lock Brake System (4WABS) Module, Break Shift Interlock, Cluster and PCM Keep Alive Memory. I am looking for some direction and hope that by narrowing it down to the #15 fuse and all that it includes will help with the possible solutions. Thank you for your time, I can't wait to see what I have over looked.

If you have a chip then make sure you take necessary precautions before killing power to the PCM.

Ok, brief update, I have unplugged the PCM relay, break switch, both alternators with no change in the amp draw. I am attempting to locate the shift interlock solenoid so I can rule that out. Is there a way to test the GEM? I don't seem to be having the typical GEM type problems like window issues or heater blower issues but I'm not discounting anything at this point. I am will to try most anything. And THANK YOU for the assistance!
