I think your biggest problem is the use of the meter.
If I understand you correctly you stated your 10 amp fuse is blown in the meter ? I can understand why with the way you are describing the use of the meter.
You cannot put an ammeter across a load. You will blow the internal protection fuse.
The lower scales may be protected by their design.
Here is how you should be using the meter when trying to measure amps. Visualize two garden hoses connected to a sprinkler. You would like to measure how much flow/current is running through the hoses. To make that measurement you need to seperate the hoses and place a meter inline with the hose so water flows through it in series.
To use the meter as a voltmeter and not an amp meter you need to do exactly as you describe and measure across the terminals.
Another way to use the ammeter is to simply remove the fuse from the circuit you would like to measure and use the meter to replace the fuse by placing your probes into the fuse socket.
That ten amp fuse in the meter is to protect the meter from over current which can damage or destroy it. Sometimes finding a replacement fuse is difficult but Radio Shack may have the right physical size one.
