memphisBred Posted October 14, 2011 Author Report Share Posted October 14, 2011 Batteries are resting at 13.0. Connections are good. Fuses in the car are good. About to check the ones under the hood.

kingsuv Posted October 14, 2011 Report Share Posted October 14, 2011 double check all your grounds Quote Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out. not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...
memphisBred Posted October 14, 2011 Author Report Share Posted October 14, 2011 I have bus bars on the front battery terminals and everything is tight. Grounds are good. All fuses in and out are good. Not really sure where to go from here. Quote SMD Super Seller/Buyer Audison----Hertz----Rainbow Link to comment Share on other sites More sharing options...

EclipseChris Posted October 14, 2011 Report Share Posted October 14, 2011 Check connection at starter terminal. Large wire should be constant hot. If it's not find out why.

blownengine Posted October 14, 2011 Report Share Posted October 14, 2011 Even without an alternator, if the battery is charger the car should start and run for a while until the battery dies. Sounds like something didnt get hooked back up, not the alternators fault.

memphisBred Posted October 14, 2011 Author Report Share Posted October 14, 2011 Oh and I'm not blaming the alt at all. I didn't hook the stock wiring up on the new alt. One I didn't think it needed it and two it wouldn't reach. Should the stock cable be reading any voltage. Touching it and a ground I don't get a reading.
