basshead4life Posted November 2, 2009 Report Share Posted November 2, 2009 has anyone done it? because i need some more amperage and i cant afford to shell out the $500 of an HO alt. i can make a bracket for where my a/c is because its fried anyway. but i need to know how i would wire them up, or do i have to get some kind of module?

Iraggi Alternator Posted November 3, 2009 Report Share Posted November 3, 2009 Should work fine. Just wire everything in parallel. Iraggi Alternator Quote Link to comment Share on other sites More sharing options...
missinglink Posted November 4, 2009 Report Share Posted November 4, 2009 Depends on what type of car. GM would be fine if older than 2005. Dodge ect... the PCM controls the alt so you could risk blowing out the PCM with the added load or get charging light. MLA Quote missinglinkaudio The United States Marine Corps.

sully Posted November 4, 2009 Report Share Posted November 4, 2009 This is used pretty regularly, in fact I am going to run a second stock alternator on the Tahoe I just picked up (needed something to pull my truck) to power everything cause I haven't been having the best luck with the HO alts lately and the brackets are readily available for the 5.3l engines. I would recommend getting a MLA module to control the two but it can wait till the money is there. You could also look into getting just the MLA for your current alternator to see if it bumps you up enough to keep you going.

tacomabanga1986 Posted November 4, 2009 Report Share Posted November 4, 2009 i was wantin to do the same thing but the price on another stock 70amp alt plus dual alt bracket could i get a good 140+ amp alt for under 300 or right around there? i think a factory replacement for my 99 taco 3.4l v6 is around $200 i think n i need more amps so i can do somethin diff n was also thinkin bout this same kinda setup, but would u halfto wire the alt plug wires in parallel with the stock one n will this throw the computer off? wuts the pros n cons to doing this? i can already see the strain on the engin tryin to turn 2 alts but will it work better with just a single ho alt?

sully Posted November 4, 2009 Report Share Posted November 4, 2009 I am just starting to get into alternators so I'm by far not an expert but i have run dual setups, and single HO alts as well as modified stock alts. From my experience the bigger HO alts put more strain on the engine than two stock alts will and you will have better long term reliability from two smaller alts then one big one. Price aside my personal choice would be to run two smaller HO alts (180amp or so) than a single 300amp alternator or price being in the equation I would run two stock alts that have been modified to put out around 15 volts.
