You want the fuse and the ammeter to *share* the current being drawn?
Or you want to measure the current being drawn *through* the fuse?
If the latter, put the ammeter *in series* with the fuse (not across
it).
HTH. Cheers, -- tlvp
No: *replace* the fuse with the ammeter. Pull the fuse & plug the
ammeter's leads where the fuse's leads went (it's not easy!). Try
soldering wires to the leads of a blown fuse (that's not so easy
either).
Of course, if you knew the exact resistance of the fuse and had a
sufficiently sensitive voltmeter you could measure the drop across the
fuse. Good luck with that!
