raytard Posted February 18, 2009 Report Share Posted February 18, 2009 stock alt is bolted to engine, which is in turn bolted to chassis, forming the circuit personally i ran a 0g ground from the bolt that mounts the alt to the engine, and grounded that to frame, took care of alt and engine ground with one thick nice wire Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
smokeumtires Posted February 18, 2009 Report Share Posted February 18, 2009 while your digging- ground the alt I've found that it has a massive impact on voltage, I try and keep my Alt ground the same size as my main power wire -Drew Ground the alt? The alternator is gounded by all the bracketry holding it in place....If the big 3 is done correctly you wouldnt need to ground the alt Quote Link to comment Share on other sites More sharing options...
Derrick824 Posted February 18, 2009 Report Share Posted February 18, 2009 It's best to ground from the alternator bracket directly to the battery. That along with the upgraded power wire from the alternator to battery will complete the circuit. Then just ground from the battery to the frame or chassis. What type of vehicle is this in? Maybe someone has pics that can help? Quote Link to comment Share on other sites More sharing options...
kryptonitewhite Posted February 18, 2009 Author Report Share Posted February 18, 2009 there should be a screw hole for bolting the wire onto the alt. tomorrow it will be done! Hey guys, NO DIMMING! THANK YOU! Sorry to whoever I went off on about not using 0/1 gauge... it's been a pet pevie of mine, and... no excuse... I'm sorry man! So it didn't take long, it worked, I have her running now to get a good charge so I can test my batteries again. Now you can all hate too that I didn't use fuses or breakers, so when my shit blows up and I kill innocent people with my fire, hey, ya'll tried to warn me! My smart ass even took a pic of 4 unopened 150A breakers I DIDNT use (I have 6 total, used 1 for power from front to back and 1 as a temporary $60 toggle switch for the amp remote :D ) So I went to walmart, got 2 terminal ring sets, 1 brace top post clamp, 1 long screw for the side post cuz 3 terminal rings per battery is hard on it so I'll test one and maybe redo them all later... and a fuckin package of TP! They ended up being 2 guage! So I brought em back, chick was like "they're not on here sir". Long story short, someone retuned a brand they dont cary and it made it back on the shelves, when i rung them up it did an "OK" beep so I thought, but it was a "not ok" beep. never paid for them! Couldn't exchange them! Ran all over to beat hell with 4 supervisors thinkin I was a thief! They apologized and let me keep them, they actually clamped better than the 4 gauge!!

kryptonitewhite Posted February 18, 2009 Author Report Share Posted February 18, 2009 didnt get any final pics that were good... don't have that nice camera anymore, back to the POS but I have a clamp on top post with ground to chassi, clamp on positive with 150A breaker power to back 2 batteries and power to alt, and chassis to motor mount bracket bolt... on the motor side after the rubber bushing even I didn't mess that up haha Quote IB3 22" Link to comment Share on other sites More sharing options...
kryptonitewhite Posted February 18, 2009 Author Report Share Posted February 18, 2009 OK, still get dimming lights, oh well. However, when testing the batteries again I realized when I shut the door, the headlights stay on a bit so the front battery dips to 12.18 but after the lighs shut off after a few minutes, it climbs back up to 12.4 or more, so batteries are OK...that's the main thing.

sully Posted February 18, 2009 Report Share Posted February 18, 2009 If you are allowing the alternator to charge all the batteries by itself, you will never get a full charge especially if you have let them get low at all. Use a battery conditioner or trickle charger and top off the batteries and you will should see a difference. The next step I would recommend is a MLA module, have the alt put out 15.3v to overcome the internal resistance in the multiple batteries and they should stay nice and charged. A .3 drop in voltage for the "don't rape me lights" staying on for a minute seems like a lot. But it does sound like you are headed in the right direction, keep it up and you will have this fixed in no time!

Torres Posted February 18, 2009 Report Share Posted February 18, 2009 x2 on trickle charge. got one of my other batteries in, charged em over night and this morning they sat at 13.x volts compared to the 12.x from before Quote Link to comment Share on other sites More sharing options...
SundownTL3.2 Posted February 18, 2009 Report Share Posted February 18, 2009 And if you can, do one positive from the battery to your main Fuseblock...you'd be surprised how much that can help out your stock accessories and how often it is overlooked. how can u ground fuse block Quote 2004 Chevy Tahoe LT...........
