    Wire from Alt to battery

    I have read on this site about upgrading the wire from the alternator to the battery to a larger gauge wire, like 2 or 4 gauge.

    My question is that the stock wire has a fusible link located near the battery.

    Is it advisable to remove this fuse.

    My truck 1997 k2500. Only one Battery.

    upgrading the wire size will remove the fusible link along with said connected smaller wire. i would reccomend placing a large fuse or large circuit breaker between the alt and the batt. I would think the protection device need be rated 10AMPS below alternator max output. these can be found all over ebay & at car audio install shops. heck, walmart has them too! amplifier install kits provide most of the materials needed. also dont forget the grounds. they just as important.

    Fuse breakers have no definitive yield point and allow spikes much higher then their rated capacity. IMHO 250 amps.

    along with the wiring upgrade, a larger alternator upgrade is also a good idea. a unit that provides high output at low engine RPM. thats my next step to my plow truck. But, sigh, no snow to plow in central IA yet. :(

    Those Mega fuses can be found at Napa.Mine has been problem free for 2 years now after I got rid of GM's fusible link.
