Extremely low voltage

[BEEKAY]

Is the voltage any better if you have the headlights on? Like Martin said you might be experiencing what Keep Hope Alive was.

Wow. I turned on my HVAC system one click on the lowest setting and my voltage jumped up to around 13.5 for a majority of the time. Before it would be at 11.6-11.8 if I'm driving under 45mph but once I go past 45mph for some reason it goes up.

I'm assuming a high output alt will help keep my voltage high and steady with no negative affects on the car correct?

Dude... Nice car

Thanks man I appreciate it!

So I just looked up on mechmans website and he has listed a 240 amp HO Alt. for 399. U think that should be sufficient enough? To keep the voltage higher and steady?

Thanks man! Def going with this mechman alternator! Appreciate it!

before you get that ALT try an external voltage regulator. Your Car's PCM may be controlling the voltage and keeping it maxed out at 12v. *****(When you bypass the internal or take it out all together the battery light will come on. this is OK.)*****

Id rather be safe anyway. I have around 2500 watts with just an optima yellow top under my hood and big 3 with 0 gauge. My under drive pulleys don't help either lol so I'd rather get a beefy alternator

Will that new ALT be coming with an internal or external regulator?

PCM controlled alts suck

Idk I would have to ask them

PCM controlled alts suck

I know!!! Any way around it?

 

[Dmac1991]

external regulation

Your main issue for one is do a ELD bypass as it forces a certain voltage.

This is my thought. Even if you go with a HO alternator (which is a good idea) an outboard regulator is a good move.

I wouldn't mind getting one, any links to a good one?
