what is going on

[skittlesRgood]

batterys are good resting at 13.4 i believe

and idk about the regulator

i wasnt talking about resting voltage. if you beat on the system for a couple min then its draining your batteries. turn the system off and it still needs to charge. so the batteries are creating a load on the alt, bringing down its voltage while it tries to charge the batteries.

its one possibility for the 13.5v reading.

high output alts cant output alot of current on idle.

i know this but at 2k rpm it about the same as 800

i heard those mla volt thingys help out a lot for getting into the 15's. try em out

ya i know but right now i dont have the money for one

mla module would do the trick if you want it stay above 14V constantly

see answer above

i know this but i put a battery (one by one) on a charger last night and it was reading 13.6-13.8 after the charge

and with the car on it was around 14.0-14.2 for most of the tym and it jumped up 2 15.5 then jumped back to 14.0

the only thing that controls your voltage output is the regulator. jumping to 15.5 after warm up is not normal

everything else you said sounds normal to me. try putting a small load on the alternator at idle and at 2k rpm and see if you have a voltage increase. you'll be pleasantly surprised...

small load..will my 4ch at mid vol work for that ?

edit

i will make a fast video

What batteries?

As i will say again in my first post to answer your question: "charging batteries is 14.4 volts. The voltage is regulated using a regulator, normally these are regulated to 14.4 - 14.7 for charging, your alternator sounds perfectly fine, it's just the regulator doing it's work. Your alternator will charge slightly higher when it is cold, that's normal but when it's warmed up it should perform around 14.4 - 14.7

I don't even get over 14 volts at all. "

Volts doesn't relate to the amps it is putting out. You could be putting out your 220amps at 14.0 volts for all it cares. The reason your voltage may be jumping is that the regulator will detect a voltage drop with your system bumping r your A/C on, it will then increase idle voltage to combat this. An MLA module means you control it yourself and also means you must manually self correct voltage drops.

I have never seen over 14v. I constantly get 12.9 volts and then when my lights are turned on it may rise up to 13.7 - 13.8. This is the regulator doing it's work. I know that is really bad and that is why I don't use proper audio batteries as my charging is no where near enough volts. My batteries rest at 12.6 volts...

When you charge them and test them do you remove the surface charge? If oyur charger charges at 13.8volts the battery may only have a surface charge...

Your alternator is functioning perfectly fine. 15Volts may even harm your cars ECU or onboard functions, albeit depending on your vehicle. Your alternator performs alot better than mine and I can squeeze 3krms with one extra car battery and a deep cycle... dropping to 12 flat with a 55 amp alt. Be happy you have a H/O...

EDIT:Kranny said: "high output alts cant output alot of current on idle."

You said: "i know this but at 2k rpm it about the same as 800"

And I say, unless you have a current meter on there that I highly doubt then it is not the same at 2krpm and 800rpm. The voltage is still regulated, but the current will increase.

At start 15+ settling at 14.4-14.9 is completely normal. Once the batts are close to charged or charged you will see the voltage slowly drop down, down, down. The ONLY way to change this behavior is with an MLA or VCM.

If you aren't seeing this kind of behavior that I stated above are you sure you have a frame ground directly to your alt?

i dont think this was mentioned, but the hotter an alt gets, the less "effective" it is.

[J00bles]

did you guys even read the posts above?

[MECHMAN]

That focus should use a white/blue regulator, which interfaces with the ECM. Voltage is always a little squirrelly when a high output unit is installed utilizing that type of regulator. Personally, I wouldn't worry about it as long as it doesn't go above 15 volts for more than a minute or so at a time.

when i said it was the same i was talking about the voltage not the out out of the amp bro,i don't play the system loud with my when i have my ac on

kranny

ya i know the hotter it get the less effective it is

j00bles

i dont think they did lol

meacman

ok thank you
