Fuse size

[rod7515]

Im moving my wiring and will be replacing the fuseable link from starter relay to ammeter. Was wondering what size fuse you would recommend using in its place. I put in a maxi fuse holder with 8 gauge wire.
Thanks Rod

No one ever change out the fusible link with an inlne fuse while moving battery??

Honestly I have been wondering the same thing. You should be good to fuse it to the safe ampacity of the wire. I do wonder what the fusible links are rated to blow at. In the bit of research I did, I see that a #8 gauge wire should be good for 73 amps DC and I fused mine at 50.

Replaced the fusible link with a self resetting circuit breaker and bypassed the amp meter, but not while moving the battery.

You are protecting the wire in the circuit so the 8WG is good but size the fuse for the wire it is protecting. If you have 10 gauge wire I would use a 60 amp, 12 gauge use a 50 amp. Definitely carry spares, fuses blow quick vs a fusible link.

Do a google search. A lot of people on other forums say its not a good idea to replace a FL with a blade fuse.
I just made another link. Wasn't hard.

Can you say "fire" boys and girls ?
To route larger wires and less failsafe into the cabin is not a good plan.
If you would put the headlights, blower motor, any other high draw circuits, on relays, you could install a lesser than OEM gauge fusible link. This smart plan requires deeper pockets though.

I am in the middle of routing stuff like my MSD, electric vacuum pump, fan controller, etc. to a Painless auxillary fuseblock. My electric fans and headlights are on relays.
I have also bypassed the ammeter and added an alternator wire around with a fusible link.
I was going to run straight wire through the bulkhead and change out all the connectors for brand new ones. After dunking all connectors in the nice used harness I bought with vinegar and salt solution and then neutralizing in baking soda/water, they came out looking great, so I made a new fusble link, and packed every connector with dialectric grease. Between taking load off the system a thorough cleaning they I think they should be fine.
