Just as a point of reference, here is the best way I've found in 'upgrading' an older car that has had a lot of electric load added without adding an entire 'load center' type fuse box.

Nissan, on a lot of their 2000+ model year cars, uses a very nice battery mounted distribution block that has fused ports...depending in which you buy you can get different amp ratings. You use the un-fused connection for the starter, and the fused ports to feed the car and take the alternator feed. It allows you to make multiple, high quality, heavy connections to the battery. I've used these when going to 135amp+ alternators and they work very well. Not too expensive, either.

Very cool. Thanks for the info. Do you get these from the junkyard, or order factory Nissan parts, or from another source?

Cheers,

Lou

There is no single part number. Nissan and Infiniti used these on a million models so there are different fuse ratings.

Here's one example. For $20 you get a Japanese OEM quality part that has several high amp fuses. There is a also a black plastic cover sold that goes over it all for another $10 (on Ebay).

On my car, I had a 135 amp alternator so I bought a 120 amp fused block to be on the safe side...if I started shoving that many amps I figured something was wrong....

These use spade terminals and can be connected up with the typical spade terminals sold in stores but it's best if you get the associated plastic molded terminal block that is part of the car harness. I just cut mine out of a car in a junkyard but it's possible they are sold over the counter as repair parts, too.

With this setup, I had my alternator fused as well as a feed for the radio/amp and a fuse for the overall car and another fuse for the EFI system. Really well protected and compact.

GregCon: A+ for this sleuthing and reporting! That's a hell of a handy piece.

I have a question. It looks to me like there are fusible links in the housing. Are they "replaceable" if one blows, or do you have to replace the whole unit?

What Charlie said. :D

I too was wondering what type fuses they were

Looks like there's a big ol' variety of these and similar products; it seems to be a fairly popular way of doing things—see here. Also looks like the individual fuse elements aren't replaceable, but take a look at that VW "battery mounted fuse box".

I never below a fuse in one so I haven't looked but I'd guess they are not replaceable. But when you lose a 60 or 80 amp fuse...a $20 replacement is probably the least of your concerns.

Keep in mind the device feeds your regular fuse block so chances are a smaller amp fuse there will/should go first. This device acts as 'big problem' protection and gives you the valuable function of providing multiple heavy take-offs from the positive post.

Very interesting , thanks for the info .
My question is what do you do with the original + wire from the loom that connected to the alternator ?

It becomes 'no longer used'. You can remove it or leave it in the harness.

No. As with most upgrades to the charging system that involve increased amperage, the ammeter is a casualty. There are ways you can make it work, with reduced effectiveness, but it's generally just left non-functional.

The truth is....by 2019, if you have a car's electrical system well planned and assembled, they are very reliable and your actual need for an ammeter is marginal.
