01tahoeman Posted May 29, 2008 Report Share Posted May 29, 2008 ummm lets see. i put my old cd player back in. temporary taped the wires together, until i can get to walmart or a parts place for clips. i have a 3 farad capacitor, its was reading 0.00 before i charged the battery, and it was reading 10.20 after. i have a 2 year old battery. nothing special. i have been hearing a high pitch noise from under the hood recently. i think its the alternator. but not sure. it gets louder/higher as the engine revs up i dont have my system wired up like i would like, but its what the place, who i paid, did. it cranked a minute ago, with the cap reading 10.20, but the sound was fuzzy out of the speakers.

SteelCityGhost Posted May 29, 2008 Report Share Posted May 29, 2008 If it cranks, then cuts off, it's most likely the alternator. If it won't crank at all, it's the probably the battery or starter. Then again, that could be the fuel pump or a number of other issues, as well. Do your lights and radio still turn on? Link to comment Share on other sites More sharing options...
ChevyBoy Posted May 29, 2008 Report Share Posted May 29, 2008 sounds like a bad alt possibly. if you can, get it down to autozone or advance auto parts and have them test everything. Link to comment Share on other sites More sharing options...

jonathancullen89 Posted May 29, 2008 Report Share Posted May 29, 2008 a car will still run even if the alt is bad, it just wont be able to run for long. i do not believe the negative is supposed to spark, here is a lil test you can do to see if yo have anything grounding out. pull both the positive and the negative fromt he battery, then take a DMM and put it on ohms and put one side to the positive wire and one to the negative. if tehre is a reading that means you have a power wire grounding somewhere. before you do this though make sure your doors are closed, light switch is off, otherwise it will give a reading because there is supposed to be power running through it to run your lights ect. 1992 cavalier build 1992 blazer s10 kenwood cd hifonics hfi2500d 6 soon to be 12 12" hifonics hfi12d4's shit ton-o-wire Blurred Vision Audio Team SMD feedback/refs. clicky!- Link to comment Share on other sites More sharing options...

And depending on how long the alternator has been bad, you may now need a new battery, also. Link to comment Share on other sites More sharing options...

SteelCityGhost Posted May 29, 2008 Report Share Posted May 29, 2008 Powermaster and Kinetik both make good batteries. Check those two out first. Or, you could even get a bigger battery from Autozone, like a Duralast or Diehard. Link to comment Share on other sites More sharing options...
