mm.. im seeing some power draws (more then usual) when I turn my fan overide on etc. Almost stalls out. I think my alt is taking a plunge.
I logged Volts with hpt and see a 13.5 13.6 Volts on that charts. And when I have my fans on for awhile and the care was stalling out.. it was at 12.8 - 13.3..for a while before it went up to 13.5-13.6V. Now i though a system is usually 14.4-14.7 when its running to charge?

I'm pretty sure that when the cars running it is right around that 13-13.5 area.
If it was 14.4, that would be awesome cause then you get more power out of audio.
Don't quote me but I think thats right.

I have anywhere between 14.4 and 14.7, says my Autometer gauge. Idleing its around 14, driving mid 14s.
My voltmeter gauge reads between 14 and 14.5 when the car is running, even with both amps and headlights on.
idling my gauge read 13.5-14, cruising, it's 14-14.5
mine is a stock eco and ranges from 13.4 to 14.1
higher voltage can be a sign of a battery going bad...the less charge a battery has, the less resistance it has, causing the alternator to put out more voltage
13.3-14.7
As long as its over 12.8 I don't worry. I know the battery is getting charged. I do know that when I kick on my fan the voltage drops to 11.3 and sometimes lower but then kicks right back up to whatever it was before minus .1 or .2 volts. It drops so low initially because it takes that much juice to get the fan started but very little to keep it going.
I used to race cars, now I race myself.

mm...when the fan is on.. its a constant 13.0 V ..then goes back up to 13.7V with it off.

a good alternator will put out 14v or higher no matter what is on at idle. These 3-phase alternators don't have to be revved up to put out alot of power. if it's anything under that start saving your brushes are wearing thin or your voltage regulator is going.

side note(if your running a big sound system the thumps might lower to below 14v but should jump back up. your car should start running rough from alternator drag before the voltage gets below 14v.)
