Big 3 upgrade help


Recommended Posts

Forget the fuse box, just leave it as is. ADD a + wire from alt to battery, upgrade your engine block to frame and battery tonframe grounds.

Edit: you can upgrade it if you want, but it has nothing to do with the charging system once you do the big 3.

You will still need to use an inline fuse holder on the wire that runs from the alt positive to the battery positive. Like others have said you dont need to up grade the wire that runs to the fuse box, but you can if you want to.

you can just use an inline fuse from alt to battery +, no need for fuse box upgrade.
