Alternator Upgrade

[mrsnicks]

Has anyone done any research into an alternator upgrade for our trucks? The reason I ask is I plan on adding power windows, shaved door handles, a cd changer and I am pretty sure I will need to up my amp output.

I have seen some 100 amp, 130 amp alternators on ebay, but they are the newer model with serpentine belt pulleys, and a different wiring harness.

If someone has already done this that would be great to. What model alternators swap in, and what is necessary for the conversion.

Thanks,
Patrick

I just picked up a load boss 105 alternator off ebay for my 70, I'll have to give the directions a good read through and get it hooked up then put up some results. It has a 1 wire hookup with a regulator already on it. Just have to see how it goes.

I've read good things about these guys:

http://www.mean-green.com/products/alternator.html

They also offer starters that are smaller than stock and intended for use with headers in high-heat conditions. Their site is not bursting with application information, so you'll have to contact them for more information and report back to us. Please.

The Load boss ones come with a lifetime warranty,just as long as you hook them up right.

I think Heep has done an alternator upgrade, I'll get his attention.

Maybe that's why they call it Mean Green. Yikes.

I run a one-wire alt on my Ford. I have dual batts, stereo, amp, 8274 winch, and 90/100 watt head lamps. Does just fine. It is only the 74 amp style. You can upgrade them to over 100amps. I got tired of the pulsing lights and fixing the old charging system wire harness. Now there is only one wire and no external regulator. The only issue you will run into is building brackets, the barely moving amp gauge will not work anymore and if you run dual batts with an isolator you will have to make a jumper wire. I like mine and have no compliants.

Heep, what guage wire did you run from the alt to the bat?

don't mean to steal this thread but I do have a question before i get too far on my truck. I am planning on putting in a 1500 - 2000 watt stereo, driving lights and maybe some neon lighting on the truck. I currently have the stock Alt on the truck and wonder if I should upgrade the Alt to more Amp.

[layedout72]

yes. you need to. I would look around for atleast 130 amps. I personally am going to run a 250 amp at idle, alternator from irragi alternators OR ohio generator alternator.

This is great.. love the information.. but I could use specific part numbers... or model numbers... Like walk up the Autozone counter and say... Gimme an alternator for a 19** Ford *****... and walk away with a 100 or higher amp alternator that will swap right in.

Keep the information coming but could use a little more specifics.

Thanks,

The 100 amp Ford large body that Leadfoot mentioned is probably the only higher amp unit that will hook up to the original wiring. You would probably have to change the brackets. Almost everything else is going to be internally regulated and require some re-wiring to mak it work.

Anyone feel like putting together a tutorial or a build-up?

Keith you out there?

When I get to that point on my project I'm sure I'll be upgrading as well, and will definitely do a tutorial. That'll be a while though, I'm sure.

on the big body Ford alt conversion really the only bracket you need to change is the adjustment side, and in most causes you don't need to do it. and if you do you just cut and weld to the angle you need or pull it of the car you got the alt off in most causes changing the belt length fixes the problem. and also the aluminum spacer behind the alternator on the pivot side some times needs to be cut down a little bit. I do this swap allot and there really is nothing to it.

if you go to a parts counter and ask for the ford 100 amp alt with a v belt
pulley theres only one the can give you now with that said it the guy behide the counter looks at you funny and ask what year just make one up like a 1980 Lincon/Cougar with a 351W and a/c should work. ford only made one big body alt.
