Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

    aftermarket stereo? Charge the battery back up, unplug the stereo and let the car sit overnight with it unplugged. Check to see if the battery drained any. Do the same with the alternator. hopefully its something easy otherwise its time to breakout the mutlimeter.

      Possible loose ground. Check all your wires. For starters, see if your alternator is even charging your battery.

          as i have said in the other thread regarding alternator issues

          DO NOT DISCONNECT THE BATTERY WHILE THE ENGINE IS RUNNING !!!

          get a proper battery/voltage tester and use it according to the instructions.

          disconnecting the battery that way CAN and WILL fry some or all of your electronics

          a tester is available for @ $20 at the auto parts store

          much less that a new alt OR computer

            with your engine off unplug the positive battery post and hook up a multimeter and put it to dc amps. You shouldn't see more than I think .02 amps or even less. if you see more than that there is a load. If you have an alarm those tend to drain a fair amount of amps when they go off. Start pulling fuses till you find which circuit is draining the most amps and start looking for shorts in that systems wiring.

              QFT! Harbor Freight has a multimeter for $4 that suits this purpose just fine. I simply test the battery by connecting the prongs to the terminals with car off... get XX volts... start car.. test again.. get XX volts. Seriously, who wants to break their car trying to fix their car?
