stevh0 Posted May 13, 2007 Report Share Posted May 13, 2007 Guys im running 2 bats and one cap . now most of you guys will say dump the cap , i only use it as a voltage reader so to speak . let me explain how its wired . From the front battery i have 2 strands of 4 gauge positive going to the back battery . From there its onto the positive terminal of the 2nd battery . then im running my earth off the body 2 strands of 4 gauge . the audiopipe cap is directly onto the 2nd battery and then running to the amp On idle it reads about 12v maybe just over or just under. it used to bump fine until earlier , when i bump it the voltage drops to around 10v and the 9v and then its starts flickering and eventually dies ? is this the cap or the battery ? its really damn annoying!

roscoe1129 Posted May 13, 2007 Report Share Posted May 13, 2007 Capacitors are only good for small systems and I wouldnt even use them then just cause they have a short life span, usually under a year with serious usage. It is probably weakening your electrical system more than anything with the extra batteries you have no need for one whatsoever. As it is probably a dead cell now it is actually drawing more juice from your batteries try to rejuvinate itself. I have seen systems with just a main battery and a cap fail solely due to the cap dying and all the power that should be going to the amps gets sucked out by the cap.

Chris Posted May 13, 2007 Report Share Posted May 13, 2007 With 2 batteries, I would say dump the cap just like you said. The cap is most likely just creating a strain on your electrical system overall. Is there anything you have recently added or changed that would maybe be the cause of this sudden problem?

roscoe1129 Posted May 13, 2007 Report Share Posted May 13, 2007 Plus, you should also have a fuse before your two extra batteries so that in case of your + wire grounding out somewhere (heaven forbid) your 2nd & 3rd batteries are not gonna keep the wire juiced causing a fire....

stevh0 Posted May 13, 2007 Author Report Share Posted May 13, 2007 not really , just the fact that the back battery is not a kinetic or optima , its a normal auto battery but just a bigger juicier version. im running a std alt is there enough charging power from the front to the back ? Ultimately is the 12v reading correct on the second battery ? Quote Link to comment Share on other sites More sharing options...
stevh0 Posted May 13, 2007 Author Report Share Posted May 13, 2007 i have a 200a trip switch in there Quote Link to comment Share on other sites More sharing options...
roscoe1129 Posted May 13, 2007 Report Share Posted May 13, 2007 (edited) test it on your amp where the power is getting used, then test each battery on forward and see if it gets stronger as you move closer to the engine bay, (after getting rid of the cap...) if it does then time for an altinator upgrade.... If you want a voltmeter get a real one and hook it up that cap is garbage. i have a 200a trip switch in there ....... is it run before the second battery?

stevh0 Posted May 13, 2007 Author Report Share Posted May 13, 2007 yeah its run after the main cold star OEM battery . basically between the two Quote Link to comment Share on other sites More sharing options...
roscoe1129 Posted May 13, 2007 Report Share Posted May 13, 2007 it should be no more than 18"'s before the 2nd battery to keep u safe Quote Some people need a sympathetic pat... on the head...with my hammer Scientia est Vox "In Nomine Patris et Filii et Spiritus Sancti" DONT BE AFRAID TO USE THE SEARCH BUTTON!!!
