February 14, 201312 yr Author how bad would it be to have that power bastardsand my new factory alt goin at the same timeI would have 2 have someone make me a bracketwould that cost more than a nice alternator?
February 14, 201312 yr Author that would be ideal but i dont have $500 atmand I have a powerbastards 220amp alt sitting aroundIf the bracket fabs under $150 that perfectI even have a couple extra runs on 1/0 gauge I could throw into it
February 15, 201312 yr Well, an ammeter would definitely show you that. In my experience, correct me if i'm wrong, but rewound, to me, means substantial higher output at whatever engine rpm is required but the idle is reduced compared to STOCK or of equal value to stock. High outputs bought from reputable companies like DC, Mechman(when they use the right pulleys) and Singer, have large idle outputs like it should be. IE rewound- Saying you have a 250A alt cold, 210A hot but only 60A idle COLD, maybe 30A hot. I read that like 5x and got confused by the end each time lol.. biggest problem with just rewinding a alt is usually if I am notmistaken you will need to change out pulley to get as many amps as youare looking for at idle. Though the largest failure to just rewindingyour alternator and not buying one from HO Alternator, Dc Power,or OhioGenerator or other quality alt. is because they are using the stockrectifiers and regulator they are not made to control that muchamperage and die other times people will put the smaller pulley so thealt will spin faster like it needs to make the amperage at idle and thebearings are old and go bad from the higher rpm's it is spinning at. Ihave also know friends who have had them rewound and didn't have anyproblems but they were only getting them rewound to a extra 25% or soover stock as that will be safe and running a 4 channel and 1500 wattsub amp. I would say it all comes down to you get what you pay for.
February 16, 201312 yr i'm not an alt build guy so i do not know what causes this or that.. etc.. So i'll try and get you to understand what i said unless i am clueless and you know more about it, which is highly possible too, hehe. Take 2 alts rated at 250ABrand A is rewoundBrand B is reputable High Output. For both brands, they will only do 210A max HOT, that's just how it is. Now, Brand B si rated to do 180A idle(650rpm), but that's cold, Hot rating is 140ABrand A(rewound) only does ~40A at idle. So at idle, you have power fluctuation in your lighting. Whether this is caused from too large a pulley or something else, i do not know. I just know that rewound alts always have extremely poor idle output and when questioned about it, the answer is always.. it's impossible to get such high output at idle(IE over 100A which we ALL know is possible).. so then they are dumbfounded when shown proof.
