Why so many Automotive FUSE Types? (Mini, Mini Low Profile, Micro, Micro3 & Standard)| AnthonyJ350

[@yolo_burrito]

The micro 3 also helps speed up assembly. If the block has 20 fuses the assembler only has to push 10 in theory.

[@AnthonyJ350]

I don't like it

[@stealthg35infiniti94]

Anthony great explanation. Every time I'm installing a Mod/Accessory to a a car I buy the multi fuse wire connector kit. Seems every vehicle picks their own style of fuse.

[@AnthonyJ350]

It's ridiculous seeing soo many fuse types in one vehicle.

[@rollandklontz]

IMO standard and mini are all thats needed.

[@AnthonyJ350]

I totally agree. I think standard can deal with heat better just due to its size and use mini for everything else that's low amperage.

[@Zerinsakech]

A Kia Forte - Base model I was working on does this, it uses mostly Short stubby, hard to grab, easily to slip out of your hand, Mini Fuses. I was curious about this style so I looked up your video and agree it's mostly for cost. yet the part store sells them as the same price or higher than common sized regular fuses. This is what pissed me off. There's a TON of space and they could have used taller more common fuses, but seeing how this car is made, every corner was cut and it truly is a budget car. I did like how the newer cars come with a fuse puller and 4 spare fuses, so that was nice. I mean it's the least they can do with all that extra space.

[@AnthonyJ350]

Cheaper for manufacturing, but it costs the end user more in servicing and maintenance. This is the trend I see in most newer vehicle designs.

[@tumblevveed3586]

One useful application I could see the mini low profile fuses used is in vehicles that are primarily ran on very rough roads, especially dirt roads. Out of all the fuses, it looks to be the most durable but I have little experience with them. I have seen over time the standard and the regular minis can break it’s internal fuse link due to constant vibration of the pins in the fuse body. They generally will not look blown and in some instances has actually made intermittent connection. There seems to be 2 causes for this in my opinion. First in some fuse panels that do not provide support for the fuse body, the body of the fuse vibrates putting additional vibrational stress in the internal fuse link to the fuses pins. Second, the long pins on them provide more leverage when the wire end terminals vibrate from the wiring harness movement that is basically vibrating the fuse box terminal very little but over time it can break the fuse’s internal link. The low profile fuse appears to have pins that are well supported in the body reducing flex of the pins and the body itself is well supported in the fuse panel. You can demonstrate this easily with a standard style pin fuses by wiggling the pins with your fingers. I may be wrong in thinking it’s a more durable setup but at first glance, that’s what comes to mind. Anyone have any thoughts or experiences with this?

[@AnthonyJ350]

Great point!

[@BAGINAZARD]

6:44 funny hearing him talk about how much space the fuses are taking when there is like a hundred empty spots that one type of fuse can sit.

[@AnthonyJ350]

Exactly

[@MarzNet256]

Awesome video. The lack of logic in fuse choice....must be a bean counter thing. Also makes it more difficult to repair as you need more parts on hand (as you said)..increasing the chance of not having the correct part.

[@AnthonyJ350]

Ya it's something alright. All it ends up doing it spreading costs to the consumer unfortunately.

[@JRTreeService-Firewood]

Great Video

[@AnthonyJ350]

Thank you!

I have a completely stock 1941 Chevrolet that has no fuse panel at all. There’s not a lot of electrical devices in the first place, but the few that do exist, like lights and the optional heater and radio, each have the old glass cylinder type fuse on the back of the switch for that individual device. So if the lights go out you feel up under the dash on the back of the light switch until you feel that fuse and replace it. So a centralized fuse panel that came along later was probably a good idea. But as is typical, the auto manufacturers couldn’t leave well enough alone and now we have vehicles like my 2017 Escalade that have multiple types of fuses in the same box. Somewhere between 1941 and 2017 was a sweet spot where we had a real fuse box but it had a single type of fuse. The question is, will the electrical system of the Escalade still work perfectly 81 years from now like my old Chevrolet does?

[@AnthonyJ350]

Unfortunately the North American market gets over complicated vehicles because we're willing to purchase them and change them after 4 years. Other markets get proven vehicles that haven't changed much like the Land Cruiser.

[@VndNvwYvvSvv]

Plenty of cases to use the low profiles in certain applications like motorcycles, especially custom choppers and bobbers, but not necessarily in a car under the dash.

[@AnthonyJ350]

I'm interested to see where the fuse panels are in those.

[@AnthonyJ350]

You got a link to the power distribution panel you use for fuses in your builds?

[@VndNvwYvvSvv]

@@AnthonyJ350 Depends on the application. Right now I'm trying to find a low-profile fuse block with 4-6 fuses to redo a 1950s Triumph chopped poorly in the 60s, but I can't seem to find any. Maybe that fuse style is still patent protected and not being licensed outside of large OEM contracts?

[@AnthonyJ350]

@@VndNvwYvvSvv But have you used a low profile fuse block to save space before? Or you just think it will save space? How much room do you need?

[@VndNvwYvvSvv]

@@AnthonyJ350 yes. We're talking about a few mm clearance between components in the same box with battery, fuses, relays, and ignition lock with electrical switch, plus toggles. The problem with most boxes is they're Chinese junk that just swaps out the sockets taking advantage of much extra clearance.

[@agostinodibella9939]

All I can say is that replacing low profile micro mini fuses under a dashboard while on your back is a real pain. They are harder to see, and extracting and inserting them with the plastic tool is no fun.

[@AnthonyJ350]

Yup

[@jeffyoutube8648]

They all work the same? Example i will use the longer one with same ampere. My car is using micro low profile.

[@AnthonyJ350]

They all do the same job. You just have to pick the one designed for your fuse panel.

[@andufuse640]

good

[@AnthonyJ350]

Thanks for watching!

[@marcaustin]

I find mini low profile can be excruciatingly hard to remove in my F150. Been having issues with boat trailer running lights going out at random. Tempted to put in a higher amp fuse because they're so d@%n hard to remove.

[@AnthonyJ350]

Don't put a high amp fuse. Check the connections at the bulbs. Is water getting in at the boat launch causing it to short out? Are they LED or incandescent?

[@tombeam]

Late reply, the Micro3 does make sense for some applications. If it's a bank1 bank2 fuel injectors or coil packs, the car isn't going to be drivable if either side is blown anyway, but 1 for stereo and the other side for interior lights, doesn't make sense logically.

[@AnthonyJ350]

There's a lot of Micro 3 fuses in the interior, and from what I've seen. Injector and coil pack fuses are under the hood.

[@tombeam]

@@AnthonyJ350 see, doesn't make sense lol, unless it's stereo and amp feeds, or interior and mood light feeds, but to have a heated seat and say the sun roof...no

[@AnthonyJ350]

@@tombeam Need to talk to an engineer lol

[@WaschyNumber1]

If they would use the fuses that light up if ther is a broken fuse, that would be much easyer for diagnostic.

[@AnthonyJ350]

Just use a test light or multimeter. Doesn't take long to check. I think that would drive up costs, but I understand what you're getting at.

[@MaCAttaK]

They do have those that light up

[@papillon5537]

I do not like Micro3 when I have to tab in something because its hard to define which side will take the actual load, carrying this always take time, I hate this ambiguity

[@AnthonyJ350]

I'm not a fan either.

[@michaelmounts1269]

Good video....as an aside...I think GM does a genuinely good job on power distribution...BUT the ground distribution of Rube Goldberg wires and straps always seems like ithey were designed by a hillbilly enginer after his 3rd Mason jar of sourmash🙄

Hahaha I totally agree. I have a video with over 2 million views going over grounds on a GM truck.

@@AnthonyJ350 The sizes have evolved over time and things do tend to get smaller with time. The old sizes hang on as many things that use them have useful lives of 20 years or more so you can’t just stop making those sizes when the new smaller size comes out. I would not say it would make sense to develop all of these sizes at the same time, but then that isn’t what happened. To say that it doesn’t make sense to evolve designs to be smaller, lighter, cheaper, etc. simply doesn’t make sense to me.
