Title: Maxi Fuse Holder
Post by: WZ JUNK on February 26, 2015, 09:11:27 AM
I want to use Maxi fuses instead of fusible links on a current wiring project.  The fuse blocks have been hard to find.    
I found this one   http://www.jlaudio.com/xd-fdbu-4-car-audio-distribution-blocks-90462    I am looking for a better price but I am tickled that I finally found one.  One of the new features in fuses is that they are available with an led light that indicate whether the fuse is burnt.  I like that idea and the Maxi fuses would be better than changing a fusible link at night on the side of a highway.

Do any of you have thoughts about using the Maxi fuses?   How about another source for the fuse panel ?

I used a maxi fuse on my 34 Ford and it saved me.  I accidentally hooked the charger up backwards and left it on for a couple of days.  Killed the battery but the fuse saved the wiring system and electronics.  I plan on always using one, didn't know they were hard to get?

I found this by searching for "fuse block" instead of holder:

Digi-key offers a wide assortment, all seem to be made by LittleFuse:

This statement is a real change, "don't know if they sell to the states".  Normally the other way around.

Or maybe a Electronics supplier, if you have one locally?

Have one that I will be installing in my coupe, got it out of a car at a Pick-a-Part.  Probably Japanese, unfortunately don't remember what make.  Maybe someone else knows.  Is a holder with two pigtails with flat connectors on each end.

I've bought from dell city before when I had my repair shop. They have good products at reasonable prices.

I've heard the hue and cry for using maxi fuses but I'm not sure I fullyunderstand why they are needed. I did a scratch harness for my '40 convert 30 years ago, paid attention to the wire gauges, terminal strips and  plug in fuse holders from Ron Francis wiring. I don't know if maxi fuses were even around then. The system has performed flawlessly with one fuse blown for the license plate light when the wire grommet went astray and the wire frayed where it went through the inner trunk lid skin.

Am I living dangerously now...is this akin to not changing your brake fluid every other year? And what circuit do you use the maxi fuse in anyway?

The maxi fuse is used as a master fuse, controlling all the circuits except the main starter circuit. Some cars use more than one. It does the same job as a fuseable link, but blows quicker. In your case there is probably no advantage to change, but in a car with one or more computers, it can save the computer in case of a short.

I don't know how to post a link from this tablet, but here's some Maxi-Fuse blocks:

Go to www.mouser.com  and search for:

Item # 576-03540505Z which is a 4-fuse block at $7.57.

Item # 576-03540549Z which is a 2-fuse block at $13.57.

These are made by Littlefuse.

Mouser has them in stock, but can probably found elsewhere as well.

Local O'Reileys store carried a nice piece.  Many listed on eBay with Littlefuse name on them

These are interesting.  I did some quick reading and the one for four fuses should work.  Strange that the 2 place is more than the 4 place.  Now I need to determine the value of the fuses for the circuits.

Hello;
If you want a 6 circuit fuse block go to the auto parts store and buy one! I also have a way to insert maxi fuses in line by cutting the wire, inserting two female spade (insulated) connectors (one on each end) and just insert a fuse between those.

As for fuse blocks:  I bought this Blue Sea #5029  off eBay for a race  car project.  Simple, easy.  $36.20  delivered to my door.

One main power feed in,  at the bottom

I already had the wire, so needed a fuse block

How difficult is it to reuse a salvaged fuse block? Every car built in the last 25 years or so has a Maxi Fuse or two under the hood. I can't imagine the yard would want much because when do they ever go bad?

The sticking point is that the "easiest" way to do so isn't the most electrically sound or best looking...cut and spliced wires. The trick, then, is the availability of terminals to accept the fuse on one side and the wires on the other, the expense of said contacts, and the difficulty of getting them in and out of the fuse block.

If that's a bad idea it shows the limitations of my knowledge. Most of the wiring I've done has been in the house and garage.

If it's a Packard, Delphi, or Bosch fuse block terminals are available. Terminal Supply is the cheapest I have found, there may be others. If you can get the terminal part number, you may be able to find the on Ebay.

plug in : Blue Sea #5029 into eBay  or a google , bing search

On eBay when the listings come up...  clik for lowest price with shipping.

eBay seller  I bought from :  radontesting :  just looked,  still offer the units. 12 circuits, $36.20 delivered

there are 6 circuit units. With or with out grounds built in.  Watch out for units that circuit just passes thru the fuse, not a main power feed design
