excessive amperage 200 amp

fit-10

finish-10

quality-7

relablity-7 (was rebuilt once already and sent back to me, just put it back on today. we will see)

output-8

customer service- 16, seriously told him there was something wrong with my alt and he told me to send it back in. he had it for 3 days and sent it back and i had it in 1 day.

Anybody running a Missing Link w/ a Mechman alt?

There are several people using an MLA module with one of our alts, they work fine on all of our alternators eccept the CS series with adjustable voltage, and the import large case conversions.

talkin to WHO at shows? i listen to people, i still never heard this. I mean HO alts will go out for whatever reason but its not because one is over 200a internally regulated. Its more user error IMO...like i said, if your runnin around bumpin your beat with a bunch of batterys and you never charge them with a charger, you are asking for trouble. Even with 4 alts, 3 of them 380's, i still charge my truck at least once a week just to keep the batteries fresh.

Often times to get more than 200 amps with any kind of decent idle output, a "hotter" custom rotor needs to be used, which can draw a lot more amperage. The rotor current draw (up to 12 amps in some cases) has to be carried by the regulator. Most stock internal regulators (and cheap aftermarket pieces) can only carry 6-8 amps before they pop. There are many heavy-duty internal regulators available capable of carrying the additional rotor draw, so it really depends on what the builder is using for a rotor and regulator combination. - this is one possible explaination of the regulator failure the CRX guy is talking about.

Another possible explaination is that a 200+ amp alternator is going to generate more heat. An internal regulator is mounted in the alternator, and therefore endures the same temperatures of the alternator. Typically, we never have a heat or rotor related regulator failure, because of the regulators that we use. -it all just depends on what a builder is using inside the alternator. An external regulator is not necessary with a well-built alternator, but it certainly has it's advantages.

...just a little FYI.

thank you mechman. im gonna get ahold of you for some of them d3100's probably soon.

I've had an iraggi 280 amp alt for over a year now, and have had absolutely no problems with it so far at all. I would give it 10's across the board. I changed from a small case to a big case GM alt, and had to get a 1" longer belt when i was told I wouldn't need a longer belt, but it all worked out in the end I am 100% satisfied with it.

well duhh, of course if its built like shit.....but ive never seen someone make a 300a alt with generic parts....my Alt guy doesnt. Theres probably some out there, but who would take the time to build one that big and use a regulator that couldnt handle it? thats retarded and it wouldnt keep you in business very long....

put it this way, a well built 300a alternator (internally regulated or not) should last every bit as long as any other alternator.

im not trying to argue with you cause i know you know a hell of alot more than i do about audio ect. mechman just put what i was trying to say in defining terms.

bottom line nothing lasts forever and im pretty happy with my 300 iraggi so. thank you dominic. shit i cant complain one bit he fixed it in a day and sent it back 4 days total with shipping and all. so props to his.

I agree, I was merely speculating as to why he has heard that HO alt internal regulators go out.

It doesn't make sense to me either, but you would be surprised how often someone's "high output" alternator comes through my door with a stock POS transpo regulator in it. Usually though, they don't fail because it has a stock rotor in it. Most little local alternator rebuilding shops stock WAI and Transpo brand components because they are cheap and easy to get, but they arn't really up to the task of higher output stuff.

its all good, maybe it could be a case of "i got me a 300a alternator now i can bump my 10,000 watt system all day!".......you know when even with a 300a you still dont have enough, but its even worse if you do that shit at idle on one of those :D

haha, true dat.
