The Power Distribution block on the vehicle battery originally looked like this on my van:

All fuses were bolted down underneath the cable lugs and the top bracket. This meant that if one fuse blew, I had to unscrew all 6 top nuts to remove and replace it.

I decided to re-assemble it like so:

This makes it a lot more user-friendly, and I can't see any downside. Can you?

(side note, I blew the leftmost fuse after almost welding a wrench to the frame trying to remove my alternator. They're not joking when they say to disconnect the negative battery cable first!)

I have done a similar doofus move and blown a fuse. I can't find any replacements. WHAT ARE THESE FUSES CALLED and where can i find some?

They’re called “MIDI fuses”

Appear reasonable at Freightliner / Dodge / MB dealers?

Europarts jist calls them “bolt fuses”.

I've thought that design was pretty stupid too. Because it needs to be accessed so infrequently I didn't do anything with it. The only downside I can see is possibly stressing the fuse tabs. Other than that it makes sense.

Added: You might inspect the alternator lug for corrosion. I think I see some residue. I believe that the OEM solder flux wasn't the best choice. Or maybe it's just dirt on the shrink tube?

Yep. Fortunately the NAS aka NAFTA T1N's have that fuse block. With many vehicles there is no fusing. They just upsize the cables. Without the fuse it could have been more of an issue.

I did it with the FB #1 removal. :bash:

Some fuse and relay info.

The High Amp Compact Fuses off the Battery are not easy to find.

I bought some spares for the NCV3 from a Freightliner dealer. This was 4 years ago but the prices were in the $1-3 range. I think Dick has posted a parts break down for the T1N in a post. That same post also has the NVC3 part #as as well. ANL type fuses at part stores are close. I had to enlarge a hole with a needle file to get it to fit over the post. It was flimsy and surprisingly more expensive than OEM from FL dealer.
