Best way to replace fusable links

[92rrrandall]

I had a major electrical failure on my 92RRC this weekend. Took me about an hour to figure out it was a fusible link. Would like to get rid of them and replace with some sort of fuse box. Any recommendations on a fuse box or fuse ratings to replace the links??

Ask Denny Dooler. He seems to have it all figured out.

I live around the corner from Denny so I will take a shot at it.

I went to Napa and bought a spool of fusible link, takes about an hour but is well worth the effort. Disconnect the old crapped out brittle wires and solder in the new flexible purdy wire and then wrap the whole thing up good n tight. Done!

Apparently only the early ninties RRC had fusable links. I decided to replace them with a #6 welding cable and fuse block. The fuse block is Blue Sea Systems part# 5026. Here is a photo of the parts. Will post a photo of the completed and on the truck

Just out of curiosity, why not bypass the links and wire them straight thru? Everything goes to the main fuse box, right?

You could do that, and that is how I "fixed" my broken fusible link after I realized it was the problem. But you are going to have to makeup a new battery cable or 6 individual wires to get the things off the car. You could buy wires with fuses in them too.

My decision was to buy a marine grade terminal block with fuses. Now I can get rid of the rotten links and have normal fuses. As a plus, there will be plenty of connection points for under hood wiring. Less Gorge Lucas, more Randall Deluxe.

Is there any problem with the fuses being fast-blow vs slow-blow fusable link wire?

 

[92rrrandall]

I was so determined to use a normal fuse block that I never considered if the were fast or slow-blow. Going to order some 40 amp fuses on monday; maybe that will be big enough. Will also make some jumper wires to use as "fuses", just in case any of them blow. Will let you know and post pictures.

My truck is also different from most other RRCs because it is stripped down. There is no ABS, heated seats, rear wipers, etc etc etc. I am also running some high amp circuits directly off the battery. So the load on my fusible links is less than normal. The reason that the link blew is due to age and vibration.

Randall, so only what 91- had fusable links? i wonder if thats a problem with mine?

 

[landrovered]

I looked all over for a suitable fuse block, checked automotive, marine and other sources. Since the truck alrady has a fuse block and adding another one seemed to be a wasted expense I went with the Napa fusible link and a soldering iron. Cheap and effective.

Landrovered:

Everyone should check to see if they have fusable links and replace them with new wire, fusible or solid. The newer models have MaxiFuses for the fusible links.

I do not recomend what I am doing unless you are able to build your own car. This RRC is little more than a tinker toy. Prototyping is my second nature. I also have access to everything electrical from my business.

If your engine stumbles sometimes...but only at one very specific rpm. Then the problem is with the alternator.

No It Stalls And The Alt Is New But Are There Fuseable Links In My Truck

What did you end up with for a fuse box? Once I get OBA installed, I might replace the positive cable with one with a pigtail; put compressor, alarm and future aux lights in a decent fusebox.

 

[92rrrandall]

What's an OBA??

Here are a couple of photos so you can get the GENERAL IDEA of what I did with Blue Sea Systems part# 5026 fuse block. Basically there is a battery cable going to both terminals on the battery, with 12 neg and pos terminals, and 12 fuses on the positive terminals.

Right now I have the 6 fusible link wires connected(most trucks have 7 links). I also have a solar charger terminated here(it is the two wires connected at the top). My headlights and part of the EFI system is grounded here. I will also be wiring my elec fans to this block

Also notice in the picture that I have removed a wheel barrel load of tanks, pumps, hoses, wiring etc, associated with the window washing system. This is one example of how this truck is being stripped down.
