soo the wire between my alt and battery melted.. helo

[rwright07]

i was drivin on the freeway when everything electronic shut off completely. got off the road and looked and the wire from my alt to battery fried. awesome. had AAA tow home and now i need to fix it.

i need to replace the wire first of all.. wondering what gauge and where the connection to alt is... never dealt w/ alternator stuff before..

second of all i think i probly need to get alternator checked and see if the regulator fried and the alt started cranking out crazy amps.. correct?

help me out again fellas

thanks

What year model any wiring upgrades?

Pull the alt and have it checked. While your there pick-up a new alt pigtail and some 12-10 gauge wire. If the alt is good replace wire, If it's not buy a new one and replace wires.

its an 85, i believe stock wiring... at least to the alternator... engine was swapped and alot of other wiring isnt stock.

about how much will a alt. rebuild run, how about a new one?

The 100 amp stock alt I got was less than $100 from NAPA.

Check your grounds. I had a cable melt when I forgot to put the ground wire back on the alternator bracket.

Dont be afraid to run a nice gauge wire back to your battery either. I know people who have ran 4 gauge, seems a little overkill but it should make the current flow alot easier. I know when Im done hooking up my dual batteries in my crew cab (after Im done with my tbi swap here ) I will be running a pretty heavy wire back to the battery along with my 1/0 battery cables.

The larger the larger the wire the less resistance it has, the more amps it can handle without overheating. I personly think 4 ga.(105 A)or 6 ga.(80 A) would work ahelluva lot better than the stock wire size. If yur wondering 1/0 is good for 195 Amps.

Sure it works better and am perfectly fine with increase in size, but I think he wants to keep it simple and stock is simple.

oooooh o.k. simple is good sometimes.
