Loose Fuses

[van_tri]

After watching a video by Dirt Road Cred regarding things to check after buying a new Jeep, I confirmed that nearly a dozen of my fuses were not fully seated. I wish I had made a video while checking them because three of them made a satisfying “click” when pressed.

If you didn't, check the relays too. Several of them are probably loose.

It gets mentioned a billion times, but I've yet to see one that was so loose it actually caused an issue. I'm guessing the robot that installs the fuses is programmed not to jamb them all the way home? If the fuse blades are making contact with the sockets, it doesn't change anything to push them in further.

Ok, search term fail on my part but I was already under the hood and honestly doubted it when I saw the video. It was only the three that surprised me with how much further they went in +1mm (insert joke) as all the others only slightly seated.

For the most part this seems to be common both here and the JLs, but it feels like a solution without a problem? Every time someone has an electrical issue, there will be a "check the fuses" comment. They'll come back and say they seated a whole bunch of them... and they still have whatever problem (usually failing batteries). Are they seated all the way from the factory? Pretty much never. Does it cause any problems? Also pretty much never. It makes people think they fixed something, but it pretty much never does.

Before I post another something is loose question that's already been covered ... The glove compartment door seems like it's a lousy fit. I have some foam adhesive gasket that I was thinking would snug it up. Has this been covered?

Not that I've seen, and I wasn't give you a hard time for posting what you observed. My point was more that fuses that aren't fully seated aren't really loose either so long as they are making the electrical connection needed.

Understand what you are saying but "pretty much never" is not absolute zero and still a good practice to check and seat them all the way if needed.

If they needed to be seated all the way, they would be from the factory. There would literally be 100s of thousands of Jeeps with electrical issues day 1. And yet the issues we see are all battery related at the 2-4 year mark. Good practice to pretend you're fixing something that's not an issue?

I disagree and will tell anybody the same again when the subject comes up.

You do you.

I've seen 100s of people get told to seat the fuses when they have a problem... and not 1 of them has come back on a said it actually fixed anything. Every time it's "They were all loose, I fixed them, but my problem is still here". Have you seen it actually solve anything for anyone?

Actually I have, plenty of times in both vehicle electronics and my work in aviation as a avionics engineer. Contact drag and connection reset are common practices to overcome electrical hysteresis in a resistance-current curve loop if loose contact point is suspected. Loose connections equal higher resistance and corresponding higher amperage even if it is in the milliamp range.

Nobody in the electrical and electronic industries I have worked in have ever said it was not worth making sure every conductive component in a known circuit was fully seated in their attach/contact points.

I am not trying to sword fight you on this subject but for something that takes less than 5 minutes to check and reseat a fuse box, I do not understand the gatekeeping of keeping someone from doing it. You are entitled to your opinion of it, but I am entitled to disagree.

Gatekeeping? If it makes you feel better, superglue your fuses in. They won't work any better than they did from the factory. Obviously the manufacturers have decided... even on vehicles they have to warranty, that they don't need to be hammered home. If you feel like it's accomplished something, then I guess it did.

I can say I’ve had a few loose fuses too. Can’t blame any personal or known issue on those but they do have this ability to loosen after setting them in. In 4 years, I’ve pressed them in twice because they wiggle loose, don’t know why but I wasn’t going to “wait and see” if I one day notice them shooting out of their places.

Loose wheel nuts and door clips have a life of their own when things keep vibrating so, can fuses pop out or, as mentioned, resistance increases to create a problem? I’m too proactive to ever find out but sometimes I do wish I had the gift of wait and see.

Here’s a real life story of a loose, wiggly fuse no other shop thought to look for. IDK, just saying…
