fox_racin4 Posted July 4, 2011 Report Share Posted July 4, 2011 hokay, my electrical consists of, a 425A mechman alt, vbcm ( set to 15.2v) 2 runs from alt to front bussbars, 2 runs of + to rear 2 runs of - to rear and 3 G31 batts ( not sure the name, but they is big) equipment, AQ3500.1 @.5 and maybe 600rms for mids/highs now, when im playing at a "decent" volume, like 3/4 volume i only drop maybe... .4 volts which isnt bad now, when im playing full tilt i can drop into the mid/low 12s most times, which IMHO shouldnt happen, with that much alt. power.. i should see much voltage drop i dont think theres no belt "dust" around alt or no squealing happening.. just not sure why it drops soooo low! 1998 gmc extd cab 12 crossfire C710s 4 SAZ-4500s 3 Singer 400A altsbuncha mids/highs Team Asshole Link to comment Share on other sites More sharing options...

optical Posted July 4, 2011 Report Share Posted July 4, 2011 make sure all of your wiring is secure and connections are not loose. i beleave mechman alts make the rated power at 8000rpm (not engine rpms, but alt rpms) Link to comment Share on other sites More sharing options...

lilboom Posted July 4, 2011 Report Share Posted July 4, 2011 what brand of wire and how are you connections? all connections are solid . then run at least 4 runs of 0 + to the rear and 2-3runs of ground from the front battery/engine ground to the rear battery then 1 -2 more short runs of ground within a foot of the rear battery also have you checked resting voltage at the batts?

Louisiana Bass Posted July 4, 2011 Report Share Posted July 4, 2011 You should have close to 0 drop with that much electrical, bad wiring somewhere would most likely be the problem. N8. No homo...unless you want there to be. Link to comment Share on other sites More sharing options...
