    re-wiring a '49 chevy 1/2 ton with the 9+3 kit from Rebel. i've decided not to use the fusible link supplied with the kit that comes off the starter.
    i want easier replacement of that fuse just in case. question is what size fuse?
    i'm not an electrical guy, but i have a basic understanding.
    the electrical system is very minimal. i MAY run a radio for now. other than that, just the normal stuff.
    NO a/c, NO power fan, NO big sound system stereo, everything basic power supply, no crazy power acc's.
    looked up replacement alternator (stock) and it calls out a 60+ amp alternator. i don't know jack about the starter though...

    any idea what size range fuse would be ideal in between my starter and panel on the 10ga. wire?

    thanks.

    I replaced the fusible link in my street rod several years ago with a maxi fuse. Never had a problem with the link, but it was buried under the carpet and not something that would be easily procured or replaced on the road.

    I also have a GM 65 amp alternator. I've used a 30 amp maxi fuse for several years without a problem.The largest fuse in my main panel is 20 amps. The 30 amp Maxi is approximately 50% of alternator capacity, so that's what I decided to try first.

    Hope this helps.

    Yea, I don't have any issues with fusible link vs. maxi fuse 'cept the ability to change on side of road in the dark...thanks for the info/advice.

    A 10 gauge wire should be 30 Amp max.

    So, in other words a "big *** fuse" is not the answer. If I go bigger than the wire itself can handle i risk it getting too "hot" for the wire but not "hot" enough to pop the fuse? So I'm gauging to size of fuse based on wire gauge?
    Thanks!
