snafu Posted August 5, 2013 Report Share Posted August 5, 2013 And the correct answer is . . . (copied from our web site): Most OEM charge leads have a fusible link on them. Its purpose is to protect on-board electronics in the event that the regulator fails and causes "voltage run-away." Although this is quite uncommon, fusing the charge lead included in any of our kits provides the same protection for your larger than stock alternator. And YES, the fuse will in fact offer protection for this as voltage is that which causes current to flow.

TeamHT Posted August 5, 2013 Report Share Posted August 5, 2013 Most. So whereas the science is there, it's not a must or would car manufacturers honestly risk that type of liability? Or is it that the risk is so miniscule it doesn't matter? Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
snafu Posted August 5, 2013 Report Share Posted August 5, 2013 It's all about dollars. IF the regulator fails and the alternator spits out 85 volts, that can burn up all kinds of stuff. Since that is really quite uncommon (I've seen it happen once in 25 years), it's simply a numbers game versus the cost of the parts required to protect the charge lead on every vehicle rolling off of the production line or to design components to be immune to such an over voltage issue.

CortezDTV Posted August 5, 2013 Report Share Posted August 5, 2013 I don't know why this wasn't said but You are never suppose to fuse ur alternator, unless you don't have a problem replacing alter at or regulators everything u accidentally pop the fuse SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...

Kyblack76 Posted August 5, 2013 Report Share Posted August 5, 2013 Still not protecting anything. If you want to cover your base go ahead, but it's useless in my opinion. Correct. Most of the fusing the OEM does, only protects if the alt goes nutty. The way i see this,.... In this figure, Where the short is... it would still be 'HOT' due to the alternator side being hot. (like fusing the link at the begining of your run back AND at the battery your going to... SOooooo 2 fuses per run front to rear. Fuse blows on one end, the other end is still hot) If you want PURE protection, you would need 2 fuses. One right after the alt, and one right after the bat post.

So go most of us who have voltage meters can tell when our regulators go out, which as snafu said is very rare, so that mean that we will probably know when our Alts we havin problems,For the average guy I'm sure fusing is fine, I will never fuse my alt My alt maker said specifically do not fuse them because the regulator "needs" the constant battery voltage, for the regulator to work properly Lets put it this way Would you feel comfertable driving you car without a battery? Hell no! You can but you run the risk of voltage spikes which the battery helps regulate, an the Alts internal regulator will be "searching" for a proper place to put all this current is producing because with most 1 wire alternators, that one wire is going into the + post so it can know how much or how little voltage and current to produce.... now would u feel comfertable driving it with out an alternator! Yes the car can function fine as long you have the reserve.... I've driven cars with bad Alts for miles, shit when I was in highschool my alt died on the way to a match, drove all the way there 20 miles, and all the way home, no alt...

Amart88 Posted August 5, 2013 Author Report Share Posted August 5, 2013 Ok, This 'sponge' being my brain, is now waterlogged lol. I'll take it all in and think. I still have the extra fuses if I decide to go that route. For now they will be sitting on the shelf for a bit until I can decide for sure. My 2005 s10 blazer build. 4 zcon 18's walled.

ChevyBoy95 Posted August 7, 2013 Report Share Posted August 7, 2013 i have also heard from a company that if you fuse the aftermarket alt and the fuse goes, it can cause the alt to overheat EXTREMELY fast and burn up not having any load on it.
