detroitdb Posted April 22, 2013 Report Share Posted April 22, 2013 anyways, ive got 4 c & d technology batteries in a bank in the rear of my vehicle, stock battery up front (brand new). big 3 done, everything wired in all 2/0 soldered everywhere... my dilema is my voltage kind of rides all over the place, as low as 12.78-14.99v with engine running, kind of stays all over the place. Any ideas on whats going on? thanks in advance.... https://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4Uhttps://photos.google.com/photo/AF1QipP7rjav9cD9UFdAYBJmz4M4LoNlF26ng1xhAf4U 2013 DODGE CHALLENGER R/T SUNDOWN ZV4-18 CRESCENDO 3.5K PIONEER AVIC 5300 NEX ALPINE TYPE R 6.5S & 6X9'S ROCKFORD FOSGATE 1.5" TWEETS 5 C&D TECH BATTS Link to comment Share on other sites More sharing options...

OrionStang Posted April 22, 2013 Report Share Posted April 22, 2013 And is that with the system playing? Or off? SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
SnowDrifter Posted April 22, 2013 Report Share Posted April 22, 2013 Is your alt PCM controlled? Did it do this with the stock alt? Some cars have this fuel saving mode that drops the alt charge voltage to the battery's resting voltage ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

SnowDrifter Posted April 22, 2013 Report Share Posted April 22, 2013 how good is the belt wrap on the alt pulley? the belt is brand new... But how's the wrap? How much of the pulley makes contact with the belt? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
LordArcane Posted April 22, 2013 Report Share Posted April 22, 2013 i mean how much of the belt is around / touching the alt pulley. if the belt is not getting good wrap it could be slipping, making it charge when it grips the pulley and not charge when it slips.
