Fusable Link To Fuses

Postby RSWORDS » Sun Jun 13, 2010 3:55 pm

Well getting ready to jump head first into switching my fusable links over to fuses. From all my reading this is what I have came up with for fusable link gauge to amp rating... Anyone confirm or deny this? The ratings just seem high to me (except the alternator)...

IIRC, the fuse rating is higher than you think it would be. I read somewhere (i think here) that somebody found a chart listing the fuseable links vs. fuse size. Pretty sure there was a link off site to the chart too.

Thats were I found these... Some list. Not alot out there as far as ratings for fusable links. So you think its even higher then what I have above?

Not sure Bobby, I had to look again at your chart to figure where you're at. I don't think I'd go higher, you can always put in a bigger fuse, but replacing burnt wires will really suck. If anything, I'd go a little smaller to begin with.

If that green one feeds the alternator, it should be about 120. Pretty sure that's what my '97 has in it for a fuse. Most of the rest are 40's and 60's, so I'd say you're pretty close there.

Cool, thanks for the help Pete.

Now to just find a fuse block that will hold the larger fuses....

Well this week I got it figured out... As with all my projects, especially the ones that you need to do alot of head scratching because there is no set way or bolt on kit to do it, I suggest you grab a couple of your favorite adult beverages first. Make life easier, I suggest...

Image

But that's just me.

So here it goes, I used two distribution blocks for car stereo amps for all the circuits except the alternator, its to high an amperage. The blocks are rated WELL over what I will pull and use standard Maxi fuses, these fuse look just like the spade fuses your used to seeing but are about 2-3 times as big. I used three 40 amp fuses and one 60 amp fuse. Also got a fused power distribution block off a 98-01 Blazer/Jimmy for the alternator circuit. It has a 175 amp fuse now because the parts store was out of both 125amp and 150amp.

I run a dual post Optima Red Top so the factory cable for the starter goes to the top post just like the factory set-up. Then I have a 4ga cable running from the side post to the distribution block/fuse. Then off that I ran two 4ga cables up stream of the fuse to the distribution blocks for the fusible links. you can get these blocks with a one cable in four out which would be better but all the stores around me had were the one in two out so I just bought two. After they go through the fuse I used some 10 gauge wire to connect them to the respected circuit. I needed to solder a terminal ring on the alternator wire to attach it to the distribution block.

Here you can see what I started with, you will notice I removed the grid heater relays. I have not had a grid heater in a long time so they were not needed but they do not have to be removed by any means, you will just have to put your blocks somewhere else. Note the fusable link pigtail that I circled in red, this is what we are removing.
Image

Here is the pigtail for the fusable links and the approximate amp rating for them.
Image

Here it all wired up. The cable coming in from the left is from the battery. The heavy cable on the right is out to the alternator, The thinner one to my fuel pump relay.
Image


Here you can see what it looked like all said and done... So far so good! Everything works! I have a little bit more clean up to do to make it pretty. Ran out of gas in my little butane torch so I still need to shrink dome of the connectors and I need some more of the black plastic protection stuff... I also need to add some shrink tubing to the cables going into the first distribution block and out of it. Just need to cover up some of the metal that's outside of the cover, don't want anything falling on it and causing a short.

I like it! Nice and clean, not a lot of extra crap all over. Good job Bobby! 8)

Looks like it will work well and does look good. So far I have been lucky with all 3 of my trucks and not had the big SMOKE issue yet. Gotta love the dodge wiring. :roll:

So I blew a fuse yesterday.....

Same circuit I blew to start this whole mess... Well after I replaced the fuse I started looking for the problem. Come to find out the wire going to the shut off solenoid had chaffed off and some grease/oil/underhood crap on it didn't allow me to see it. Well it would shirt out against the throttle bracket and short out the circuit.... Just a heads up!!!

So now that you found the original problem are you going to pull that new crap out and put the fusable links back in?

I need to add a 2nd fuse/relay box for all my extra crap. I have 1 from a jeep, but I like how yours looks better. I'll have to find me a 2nd gen one.
