Loslam Posted April 7, 2012 Report Share Posted April 7, 2012 (edited) If it stayed in 12s and lower I'd say it wasn't wired up. But you said it is 13v sometimes and used to be 14v. Sounds like your alternator is going bad/funky or either you're losing a lot of voltage through wires to the back Recheck everything. Make sure harness is plugged into alternator firmly, make sure all wires are tight Edited April 7, 2012 by Loslam Quote 1997 Chevrolet Silverado Extended Cab, 350 Vortec Things to come at some point...

soundstream15 Posted April 7, 2012 Author Report Share Posted April 7, 2012 everything is good..i took the dmm and put it on my alt to battery and it said 14v, like tonight i played my system full tilt and my volts said 12.6 so when i played it full tilt it didnt move so when i turned it down it raised to 13.6 then went back down..this just started today and i dont understand why, everything is as good as it was yesterday and that..im thinking the battery is going bad Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted April 7, 2012 Report Share Posted April 7, 2012 im having a hard time understanding you. so you measure the back and front battery at the same time and the back one reads lower than the front battery? what brand is the alt you got? where did you get it?

soundstream15 Posted April 7, 2012 Author Report Share Posted April 7, 2012 pretty much, i took the dmm and my alt is charging my front battery just fine and reading 14volts but today when i put it on my back battery it was reading 12volts, when last week i checked it and it was 14volts, everything is wired just fine and shit, and not sure of the alt man..got it from autozone, i no my volt meter is going bad cuz it reads some funky shit..there were times where it read 12volts and i put the dmm on my rear battery and it said 14 volts but not today Quote Link to comment Share on other sites More sharing options...

01VWGREENMACHINE Posted April 7, 2012 Report Share Posted April 7, 2012 check your fuses and what brand of alt where did you get it from i have 2 volt meters in my car 1 directly to my 200a singer alt (it is a beast) and 1 on the back battery. know when at idle i sit at 12.7 v but when i rev my motor it goes to 14.1 if i run my system fulltilt at idle my volts will drop to high 11's but if i rev my motor 200 rpms my voltage doesnt drop at all it effects both the front and the rear batt the same way Quote http://www.stevemead...f-system-build/ 2001 VW GTI with a 1.8T motor BIG 3 Pioneer AVH-4200DVD DOUBLE DIN HEAD UNIT 6 - 4 VOLT PREOUTS RF T1500-BDCP (running at 2 ohm) RF T400.4 RF T1 D212 x2 (in ported box) RF 1/0 TO 4 GAUGE distribution block x 2 all stinger wires 200a alternator (SINGER ALT) RF T2652-S (6.5 MID BASS AND 1" TWEETS in front and rear) KINETIC HC 800 BATTERY (Front) KINETIC HC 1200 BATTERY (BACK) 120ft of 1/0 stinger blue and clear matt 20ft of 4 gauge stinger blue and clear matt 30ft of 8 gauge stinger blue and clear matt 100ft of 12 gauge stinger speaker wire black Link to comment Share on other sites More sharing options...
KOZ89 Posted April 7, 2012 Report Share Posted April 7, 2012 like he said he doesn't know the brand name but got it from autozone, i'd run a jumper to the back battery or take it off, put a little jumper on it from the alt or the front battery see what you come up with Quote build coming late April, early May build log for 1 LVL 5 18" 87%ish done : http://www.stevemead...ab-dc-lvl-5-18/ 1997 Dodge Ram 1500 Slt Laramie Amplifier - AQ3500d.1 Sub - DC LVL 5 18" Highs - (2x) Selenium ST-350 Super Tweeters 8ohm Mids - Selenium 6" 200w midrange 6W4P (pair) Mids/Highs Amp - MB Quart ONX4.125 1000watt 4 ch Wiring - XP Flex 25' Red, 25' Black Alternator - Mechman 270amp Battery - XS power D3100, 1- Yellow top front more to come...
