Thank you everyone for your input. Here is the short version: 'Catback23' was absolutely correct and when I tried his suggestion, the fuse holder worked as stated.

Here is the long version: I went back to Radio Shack on Saturday and told them I had a defective fuse holder. I had brought my DMM but the guy behind the counter had a hard time understanding what continuity was and told me to go get another holder. Now when I opened the 2nd one and tested it, it also showed 357Ω from end to end (without a fuse). At this point the RS guy had wire cutters in his hands ready to take my old one and give me a replacement but I told him I was going to keep what I have and left.

When I got back home on Saturday, that is when I read 'catback23' post and was glad I didn't let the RS guy cut my wiring. I didn't have access to my car until this morning, and as soon as I could, I tested the leads as per his suggestion. The led glowed bright when there was a load placed (no fuse). All is well now. Thank you to everyone. This issue is now solved.
