Electrical and fusible links

Asked by Jnice101 Dec 19, 2019 at 10:25 PM about the 1980 Dodge D-Series

Question type: Maintenance & Repair

Hi everyone,
I am in the process of replacing some fusible links
in my 1984 dodge d150 318/auto.
I am replacing where it comes off the battery the  
splits into 4 separate fusible links.
The wires are ignition feed, ignition switch feed,
battery feed, and alternator charge wire. Since I'm
replacing with fuses I'm wondering what amp
fuses I need for each one. Also do I need a mega
fuse for the main wire feeding the 4. If so what
size. I plan on replacing with jcase or slow blow
fuses.

It's usually best to go with how things were designed , To take on a job like that and have to ask questions here sounds repugnant , I guess you could go with any mega fuse block with 80 amp fuses ,.

You have to ask questions in order to learn right? I'm tied on what to use. I believe I have a 60 amp alternator but the rest I'm not sure if I should base the fuse size off wire gauge or not. I want fuses for ease of sourcing blown fuses and replacements. Jcase slow blow fuses are rather similar in they can handle power spikes without blowing right away.

fusible links don't blow unless you have a problem , they shouldn't be "poppin' " at all .And it would probably be cheaper and easier to put in the links . I'd even get them from the dealer as most anything after market can be junk
