If you don't have at least 150 amps of electrical load, there's no point to a 200 amp alternator, as you'll never use the capacity. Why pay for something you don't use?
Alternators don't put out max current just because they are spinning. They put out current in response to demand, up to the max they are capable of under load.
Didn't say that. I said don't waste your money on a 200 amp unit unless you KNOW that you need that kind of capacity. Go get the one you have tested, and you'll know for sure if you have an alternator problem or not.
my headlights and dashlights are flickering. The car does have a system but the problem occurs whether it is on or not.
would the alternator be the problem? do you think I just need a new alternator or a 200 amp?
If you recommend a 200 amp, where do you get them and what else would I need? Prefer a direct bolt in.
Thanks
call me wrong. but ever since i got my ta. it does that. its not a strong flicker but a mild? but noticeable? mine does it too. i herd it happens in alot of f-bodys? if it was your alt. i think your bat might be dead by now.
The flickering lights usually is indicative of the voltage regulator in the alternator not working correctly. Mine got so bad that the headlights and dash would actually strobe quickly. I replaced my alternator for a new one (not reman.) and it fixed the problem. By the way, if you take your car to autozone/oreilly's they will be able to see that the alternator is not putting out a constant voltage which would be the regulator going...

I had the same problem after a system install and some additional guage installs. I had the upgraded ground wire for the battery that you get with the racetronix hotwire kit. I installed the ground wire, believe it or not, no more flickering. It's cheap and maybe worth a try.
200 amp alternator?
