All 0 ohms means is you have a good complete electrical circuit. Like you want zero ohms or as close to zero when testing cables, connections, etc. resistance causes heat, heat causes meltdown and possible fire. You only want resistance from items designed for it.
If you get continuity through the fuse, then it's fine. The fuse can get hairline cracks in it. It's best to remove it to test.
What brand GP's did you get? I found Bosch 80006 at Auto Zone for $9.99 each. I replaced all 5 like a maintenance item.
You can test all of yours by pulling them and giving them 12v to see if the tip glows. Just because a GP passes the ohm test does not mean it's good.
