jeepwrangler11 Posted April 27, 2010 Report Share Posted April 27, 2010 So I recently completed the Big 3 well the Big 2 being that i didn't have enough wire or terminals. So I ran a 4 gauge stinger wire from my alt to my battery positive and two 8 gauge stinger wires from my engine block ground to my battery negative. It went well for a week or so and today I noticed my voltage that was at 13.7-14.1 is now at 12.4-12.7 I don't know why my voltage is dropping now. I am running a stock 90 amp alternator thats why i don't have a fuse inline with my power wire from alt to batt. I don't think my batt voltage should drop from high 13s to mid 12s even with a big 3 and i'm running a small 200 watt amp. 1998 Jeep Wrangler Tj Sport 4.0L Headunit:Pioneer AVIC-N2 Front Speakers:Boston 746 Rear Speakers:Boston CX-6 Speaker Amp:Kenwood KAC-526 Subwoofer:Kicker Free Air Competition 8inch Subwoofer Amp:Kenwood KAC-428s Wiring:Stinger 4&8 Gauge, Rockford Fosgate 16G Big3 in 4 guage stinger and two 8 gauge stinger wire Rockford Fosgate Battery Terminals,Connections and Distro Block Rockford Fosgate Signal Cables *UPGRADE COMING SOON ONCE SUBS AND AMPS ARE DECIDED* New Subs Two Sundown SD1V2 10's Link to comment Share on other sites More sharing options...

Skullz Posted April 28, 2010 Report Share Posted April 28, 2010 Maybe the connection at the alt loosened up so check that and all other connections and make sure they are tight and clean, if that hasn't solved the problem then have the alt checked out. Make sure the alt belt isn't slipping either. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
jeepwrangler11 Posted April 28, 2010 Author Report Share Posted April 28, 2010 Now I don't know if it could be bad but my battery is wet cell and not AGM. I'm trying to sell my Shuriken BT20 so I can save up to get a Xs Power or the Shuriken biggest battery out now. 1998 Jeep Wrangler Tj Sport 4.0L Headunit:Pioneer AVIC-N2 Front Speakers:Boston 746 Rear Speakers:Boston CX-6 Speaker Amp:Kenwood KAC-526 Subwoofer:Kicker Free Air Competition 8inch Subwoofer Amp:Kenwood KAC-428s Wiring:Stinger 4&8 Gauge, Rockford Fosgate 16G Big3 in 4 guage stinger and two 8 gauge stinger wire Rockford Fosgate Battery Terminals,Connections and Distro Block Rockford Fosgate Signal Cables *UPGRADE COMING SOON ONCE SUBS AND AMPS ARE DECIDED* New Subs Two Sundown SD1V2 10's Link to comment Share on other sites More sharing options...
