Battery Draw?
I am showing .25 amps + - . If not mistaken that is 250 miliamps. I pulled every fuse and relay and the only thing that changed the current draw was the battery saver relay in the inside fuse box. It took it down to .17 amps. The other fuse tha did any thing was maxi fuse 105 under the hood. The manual says it is the junction box battery feed. I also disconnected the altenator wires at the alenator and also disconected my brake controller and scangauge 2. Any ideas?

Update...
I didnt relize that you had to wait about 30-40 min for the relays to turn off as well as the computer. After a 20 min trip last night I popped the hood so I could open it after all the doors were closed. I waited an hour or so and then checked the current draw. If I check it without letting it set for an hour it showed 250 + -ma current draw. After an hour or so it now reads .03 + - amp. which is 30 ma. That is what it should be. I checked it after 8 hours and it is still reading .03 ma. So for anyone doing these tests be patient and wait to see what happens when everything goes to sleep.
Pop the hood and follow these directions

Pop the hood and follow these directions
- Make sure to loosen the neg battery cable but dont take it off the battery post
- your meter should be set to the highest amp setting and your pos probe in the amps hole of the meter
- very carefully hold one probe on the neg cabel and the other probe on the battery post. VERY IMPORTANT not to break the circuit.
- note what the meter is reading. If you have it on the 10amp setting you should see no more than .05 amps which converts over to 50 miliamps.
- do not break the circuit and hook everything back up.
- Wait an hour or so.
- Re test as above. VERY IMPORTANT not to break the circuit. If you do hook everything back up and take a 5 min drive and start over.
