altenator question

[militarymustang88gt]

is there a difference in the plugs between the 95 130 and 200 amp altenators?

[EHardy1971]

If you're talking about the 3G type,no,the only differences in them are internally.The armature and field are different (and sometimes larger along with the case),as are the voltage regulators.Are you doing a 3G swap on yours?

[militarymustang88gt]

ok so will that give me more charge power? i have no idea about how all that works. so if i get a 200 amp i would just plug it up like normal and it wont fry any of my electronics?

[EHardy1971]

It will give you more juice,but it won't fry anything as long as it's wired up correctly,the voltage regulator does just that,regulates the output that is needed.It's not a plug and play swap though,I did it on my coupe with a 130a from a '98 V6 car.One of the best mods/upgrades you can do to a fox,if you need any pointers,or pics,let me know if I can help you out! I'm not sure who all on here has done that mod,but I *think* coupe,Qwksnke,and ItalianLX have done it too.

give me some help lol I havent swapped one in yet and its coming hit me with pics and detailed info but as a favor to everyone would you post it on the site so it can be searched later on.I usually buy moddded stock cased alts.I want to do a stock alt from the newer cars just so I can find in junkyards.

[militarymustang88gt]

ok cause i know at night time i notice it is only charging at like 12to 13 and during the day it only charges around 13 1/2 ish. so i am thinking i need to upgrade.

[QWKSNKE]

I didn't do it on my car but i know there is something different. PM Italian LX. He did it on his car

[militarymustang88gt]

ok cause i am wanting to do the 200 amp if possible. i am going to run hids on it and thinking about puting my subs back in it.

There's only a slight bit of grinding on the bracket required and running a larger gauge wire to the battery. Ryan has a good write up on his website:

Also, he has kits that includes all the wire, fusing, connector, etc... if you want to do it right.

I bought my alternator and one of his kits and everything was top-notch and decently priced. However (unless things have changed from a year and a half ago), be ready to possibly have to wait a few weeks for shipping because he stays pretty busy with other things.

I was trying to find the write up they have on the corral about it to post it's link here as well.Military,is that your voltge at idle,or cruising?

[militarymustang88gt]

cruising. i am running like 11 or 11.5 volts at idle. it sucks. i put a new altenator on and it didnt help. italian i also have a 2 guage wire running from my battery in the back up to the solenoid. is that enough?

[BAD INT]

what can you find the 3g 200a on?

50 resto or jegs has one for like 160 but other than that i dont know

One of the major factors contributing to that is your alt. pulley size. I am assuming you have an underdrive crank pulley installed. It sounds like to me that your alt pulley is too big. You want to lower the trigger point (or charge speed) of the alternator. In order to do that, you need to reduce the size of the alt. pulley. I have one that should drop your charge point about 200 rpms if you need it. Because it looks like you're not getting a charge at idle.

[militarymustang88gt]

no underdrive pullys. just the stock altenater. it jumps to like 12.5 when i start driving but that is it. and when the lights are on at night it never leaves 11.5ish.

If you don't have underdrive pulley's, then you need a bigger alternator. I have an electric fan and a big stereo & when everything is on, I still don't go below 13. My alternator is a 130 amp. If I were you, I'd go 130 or a little bigger.

[militarymustang88gt]

is there anything special you have to do to use the 130? i know for sure now that there is for the 200 but what about the 130

The only thing I had to do was remove the plug end and crimp on the ring terminals for the stock 8ga. wiring as the alternator has a "1-wire" hook-up. The other "3-wire" plug went right in to a stock-style voltage regulator. I was advised that anything over 130amp, you should bypass the stock wiring and use a new 2ga. line like you installed.
