I had some wiring issues around the alternator and decided to just rewire all around the charging circuit.
Found some parts around town to make a crude but effective fix. This could be a great fix for someone stranded with a bad fusible link (diagram below with pictures)
I wanted to get rid of the fusible link because I was seeing voltage drop.
Fuse box was found at Walmart
All else I either had on hand or was bought at Oreillys including the 40 amp fuses.
14 gauge fusible link wire found at Oreillys.
I also replaced my ground from my battery : 10” 4 gauge wire to body (next to battery) mated to what is I believe a 32” 4 gauge to ac compressor bolt.
The 40 amp fuses are essentially replacing 2 parts of the fusible link. The third part of the link is the protection from the 14 gauge fusible link wire. This protects the alternator portion. You don’t want the alternator on a fuse. The rest has been perfectly fine on those 40 amp fuses. No issues or blown fuses. And the 40 amp rating is very close to what the factory design of the fusible links feeding those circuits are. I have had excellent charge with minimal voltage drop. My voltage meter I installed reads 14.2 V at 1000rpms. Needs some heat shrink and organizing but this is my daily driver and I needed a quick fix. If you have a short around the battery or alternator this could be a good upgrade.
There are some ways to improve on this design. Feel free to suggest.
