[Fordfool302 10+ year member]

I need more power, I have 0 ga wire 3 extra redtop batteries a 15 farat capacitor and a stock sized 100amp alternator. does anyone know where I can get a kit to rewind my alt to put out alot more amps then it does at lower rpms or have a solution to get more power.

thank you

umm dont rewind an alt ur self... take it to a local alt guy or better yet get in on the Iraggi Alt group buy

I agree, get in on the iraggi group buy, works a ton better that way

15 farad cap? are you running 15,000 watts? how much did you pay for that?

15 farad cap isnt going to power 15,000 watts

Upgrade the alt. Dont just rewind it. IMO you would be better off with a bigger alt.

If my memory is correct, 1 farad is good up to 1kw. so 15 farad should provide enough for 15kw. Although in his case the cap and batteries are doing nothing more then hurting his power.

isnt the cap thing 1 farad per 1000 watts? i wanted to know why such a big cap when he doesnt need it

are you sayin the cap ALONE will work with a 1kw?

I tend to go overboard when I buy thing as you can tell. At the time I got a really good deal on the cap.

How about this my boss who run his own automobile shop can built an alt braket for extra alt. I was just going to take my a/c compressor out and put an extra alt right there and run the main audio power off it so there would be now draw on my electrical system. Also how many amps do think I would need to power everything properly.

Please explain how the cap and batteries are hurting my power?

Well lets actually address your issue - why you think you need more power?....What is your voltage at idle - no accessories on/ then with Stereo on. Check at rear batteries and front battery.

The whole HO Alt trend is really something, most do not understand what actually takes place when you upgrade. 9/10 times upgrading means same size case, better internals which are wound for higher output with some efficiency loss at idle. No matter what there will be some trade offs just like a High Current Amp's power supply is wound different for higher output at low impedance - so is a HO Alt's stator and Rotor assembly.

By using the same case, installation is simple and direct bolt up. I would say very few cars can accept a larger case unit without major work. This is where "rewind" term comes in to play. The stator and rotor are wound differently, they basically create a larger amount of current due to how the unit is wound. Local shops do not usually wind there own parts and have facilities do this for them. The machines are expensive and large. So a "Rewind/Rewound" unit is the same as a HO Alt. They use the same parts internally.

I have had my hands in Alternators and Starters since I was 6 years old so I have a good idea what takes place in a rebuild. I would not recommend doing it your self unless you have some experience. Your unit is a very straight forward rebuild if just replacing all the internals, it requires some heavy soldering tools. Keep this in mind, even if you buy the parts to make it a higher output, most places will not warranty parts - so if you goof your buying another component. Probably easier to rely on an experienced shop

ditch the 3rd battery and get a bigger alternator.
