Alternator shot. Why?

[Kid Coconut]

Hello,

Greeting from the Caribbean.

My son raves about this forum so I thought to post my question here.

I think I have a pretty good idea but want to hear from you guys.

I have a 2004 Ford E-350 Van with two stock 850Amp Batteries.

To this I added two Kinetik 3800's and an Excessive amperage 250 Amp Alternator to supply the following:

All zero gauge wires installed.

I have two FI 15 BTL's fully loaded (daily) They are wired at 1 Ohm.

Each is driven by a Hifonics 2610D amplifier.( rated at +/-2600 RMS at 1 ohm.

I was still breaking the FI's in when the Alternator just quit after about 10 days or so.

Afterward I found out the small pulley had been replaced with the larger stock one otherwise the Belt was too big.

The last I played the system was in a parkinglot Idling and with the AC going.

I have ordered two Batcap 4000's and Two new Excessive amperage 350 Amp Alternator along with the needed bracket to run both if needed.

I assume that the alt went out because of the combination stock pulley and idling.

My question is if I install just 1 350 Amp Alternator with the smaller pulley, will it be enough with the stock batteries and two Kinetik 3800's or would you say go ahead and add the second pair of batteries as well?

If my plans are still wrong please let me know what I would need to do.

Thanks.

One 250 - 300 amp alt would be plenty and 2 batteries, I would run 2 XS Power 2700's and a diffrent Alt company, as I never had good luck with my EA, not saying you won't.

Thanks Andrew,

This was my first EA alternator. Lets see what happens to the next two which are 350Amps.

Ok I have two Batcap 4000 for sale....lol.

my excessive amperage alternator killed its self without a system in the car. they are garbage in my opinion.

what part of the Caribbean? ive been lots of places down there

Ouch ...don't say that. I have two brand spanking new 350 amp alts on the way.

I'm in Curacao.... Right in between Aruba and Bonaire.

About 50Miles off the North Coast of South America,

Lmao...awesome is right.

It has been renovated and modernized like you would not believe.

Coblestone walkways,beautiful rooms with AC, dvd player,etc,etc.

Like I said lots of technology.

Were you stationed here on the US military base?

your alts probably died because they're not "high end" in the world of alternators. they just tend to break and wear out over time.

my other guess (which i have never seen proven) is that the combination of the stock lead acid batteries and the AGM batteries were causing the alt to charge incorrectly. i would try replacing those front batteries with some similar kinetiks.
