You need to use a resistance checker to test a fuse.
Or just replace it with a new one.
If the fuse is ok, then a wire/electrical connection may be broken or the choke may be bad. A voltmeter is useful.
There should be a resistance check for the choke.
If you don't have a digital multimeter, you should buy one.
Sears has one on sale usually for about $15. It is rugged.
