O.K. I am impressed you know what a parasitic drain is and how to locate. Fuse controls seat belt/key warning light alarm, theft deterent system, radio, Data link connector and electronic brake control module. If it was seat belt you would see and hear it key out scratch that, theft needs power key off, Radio no brainer, DLC no way, Elect brake module maybe. How many amps is draw? What's meter drop to when # 10 pulled?

Thanks for your quick responce and sorry for the delay in replying to your question-it killed the battery. New battery now. We think there is a 2.0 amp draw-when 15 amp #10 is put back in the draw is 2.8amp -does that narrow it down? Is 2 amp normal or too much?

Allowable draw is.5mAmp your way over. Need to start unpluging components. Do you have a manual with wiring diagrams? Will need Behind glove box is anti-theft module and seat/key warning relays. Locate and pull them see if amps drop.
What is amp draw #10 out?
