I have a problam with battery draining in my2002 f250 xltwith 7.3and only 100k .The auto elec has just about pulled the whole vehicle apart but still no luck with finding where drain is happining. All plugs have been pulled of computers radio doors alternator abs under bonnet light and they are starting to talk about burning it not really but they are running out of ideas.Can anyone help with ideas as this is starting to get expensive.

If they can't find it, do what cartmanea described (yourself). Sometimes you do not get thorough work from folks (I have been there on this exact situation).

Couldn't you do this with the fuses in? I think most fuses have a little opening where you can get a MM in.

The ammeter has to go in place of the fuse so the current flows through it. If you try measuring with the fuse in place the current will go through the fuse and not through the meter and it will not measure anything. Those points are for measuring voltage.

Makes sense to me, that is why I asked. I only know enough about electrical to be dangerous
