Socky Posted September 13, 2010 Report Share Posted September 13, 2010 Shouldnt, your factory voltage regulator will stop you from overcharging your car. It most likely will be like 14.3 or so, but no it should not.

TeamHT Posted September 13, 2010 Report Share Posted September 13, 2010 voltage does not equal current. easiest way to think about it, in my opinion, as your alternator as a generator, which in nature it is. and only produce as much current as needed. and if creating max current the current will be used towards the electronics drawing the current. so most of the time you anticipate where the need is going to be...ie: big 3 and power wires for the amp/amps. not to mention A LOT of alternators have internal regulators that keeps the alternator chargin anywhere from 13.8 to 15.5 at all times. some have external regulators that allow you to adjust the voltage the alternator charges at. i think a lot of the myth started when racing alternators were first being used and charging at INSANE volts DC that were frying most stock 4g and 8g wiring. but its been years now and most companies and users have learned from experience.

What are you running? Are you sure you need a alt? You may be fine with a good battery.

rubbernutz1 Posted September 13, 2010 Report Share Posted September 13, 2010 yeah you definately need to have the capacity to store or use the power the alternator makes if its a huge one, like 300 amp. i mean if you got1 battery and your using a 300 amp alt then yeah your gonna fry something. either the alt is gonna burn up or your gonna fry the battery. if you got a couple batteries to store the power then you should be ok with the system off. trust me i know from experience lol. i had a 240 amp on 1 big battery and it cooked it without the system on Quote Link to comment Share on other sites More sharing options...

You could run a 350 amp alternator on a single D680 (tiny) battery and not have any problems so long as you start off with a fully charged battery. The only time you could run into a problem, is if you ran the battery dead, then started up the vehicle. The voltage regulator will maintain steady voltage, which prevents anything from getting "burned up." The only problem, is that a very small battery would not like being charged all the way up from dead via 300 amps, but that is an extreme example. As a general rule of thumb, it is totally OK to run a high output alternator on a stock battery.
