Met-B Fuse and random current draw. HELP?

Hi,

I need some help. I'm been chasing my tail with a random parasitic drain. Finally I caught it today and it was on the 5A Met-b fuse under the hood. It was just under 200mA and when I put the mV meter on the fuse I saw a fairly larger reading. So I pulled the fuse and the reading dropped to under 40mA.

I just pulled the wiring diagram and it appears the only thing on this fuse is the instrument cluster? Am reading this correctly? Any advise on the next step?

I do have an AMP clamp and meter so going forward with any testing should be pretty easy.

Thx in advance for your help

 

Can anyone confirm my assumption that the Met-b fuse only controls the instrument panel?
