Parasitic draw

Thank you for the response on my last question.
I have done all the test advised except the one that involve the voltmeter. I just noticed that

1. One of the fuse holes is not suppose to have fuse at all according to Volvo and the information in the fuse box(drivers side) but there is 5amp fuse fixed there.

2. There is another hole with 20amp written on the panel but I have a 30amp fixed there.

Can all this cause this draw?

I tried removing the fuse (5amp) but when I parked the car I noticed that the negative cable is a bit warm this was always cold before the removal.

Once again thanks for your response.
