Not enough alt, battery, or both bad?


Recommended Posts

Ok losing 1.5-2v at full tilt. Stock 150a alt. d3400 under hood and hc2400 in the back. I've charged them both regularly. Big 3 is done. It used to run 13 full tilt now can drop low-mid 11's.

What size wire to rear. CCA or OFC? Your alternator is stock it needs upgraded. How long do you run it at full tilt? pictures of grounds? Did you remove any wires off the alternator (stock)?

Well OP you are running 2.5kish, no chance you'll stay above 13v with that equipment if your amps are making decent power.

That 2200 could pull most of the current the alt is making just by itself.

i shook this one kids hand and it just folded in mine. long story short i fucked his girlfriendso.. yeah..

You want this to happen to you? Give decent handshakes people.

my bad, I was on mobile before and couldn't see that....

I agree with emmet....May want to start looking into a high output alt.

What does "used to" mean? Did you change anything or it all of a sudden started acting up?

1/0 to the rear. I know I need to upgrade the alt. it will happen one day lol. I did not rove any wires during big 3.

It seems to have happened more after I upgraded my boston amp. It just doesn't seem that running it stereo at 1.5 ohms like the last one I had would be that hard of a drop. By used to I mean within the last 6-8 months and it's been steady since then.

If I add another hc2400 and a 270a mechman would that be sufficient to run as a daily if I upgrade to an sq 3500.1?

My GT-2200 used to draw a shit load of current. Have you load tested your batteries a cell could be bad.
