00sdime00 Posted December 8, 2008 Report Share Posted December 8, 2008 we have tried everything u asked BUT either way u should be able to get a 3 sec burp out of a bank of 7 big batteries with only 4 amps.I understand that...but by what I have read almost EVERYTHING points to a problem in your battery bank. How old are those battery's? How long were they sitting before you put them in? How long has it been since they have been charged? The fact that you so far have found only one bad battery does not mean that there not others....I'd do like Tommy suggested on the Termpro forum and load test EACH battery......A battery can look good with no load applied, but as soon as a load is applied, it falls flat on it's face. I'm just trying help out brotha...I'm an electronics technician by trade, and it's my nature to ask so many questions. A half-wit gave you a piece of his mind, and you held on to it.

dwright27 Posted December 8, 2008 Report Share Posted December 8, 2008 im still stuck on the ONE alt not being able to charge all those batteries. and with you running each amp @ .66 ohms, you're definately pulling around 400 amps from EACH amp. at 1 ohm these things pull 350+ amps. 350*8=2800. 2800 minimum amps. do you really expect 1 250 amp alt to charge 2800 minumum amps to 10 batteries?? 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

2000LaDe Posted December 8, 2008 Author Report Share Posted December 8, 2008 its a 3sec BURP! on a charged bank. ive got plenty to do a burp. when i burp is when it does it. ive got plenty of amperage to do a burp. so all of us here have came to the conclusion thats not the issue. yes i got 1 alt but im doing a burp right now with charged batteries with the vehicle off. im not being a smartass at all when people suggest something because we have tried everything that could possibly come to mind besides maybe the wrong freq for the burp which is causing the amps to work harder than they should which is causing them to draw more.

00sdime00 Posted December 8, 2008 Report Share Posted December 8, 2008 You said that you took an amperage reading on the amps input right?...........that should have told you if the amps were drawing excessive current...I feel like I am missing something here....

2000LaDe Posted December 8, 2008 Author Report Share Posted December 8, 2008 we took the output reading of the amps. and the voltage reading while burping. they are definetly drawing more than they should though just by looking at the voltage.
