Car Wont Crank


Recommended Posts

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.

SOMEONE HELP PLEASE

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.

it cranked after i charged the battery. when i hooked the negative back up to the battery after i installed my cd player, it sparked. which the negative shouldnt spark, right? but that was like a week ago

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.

Yep, that's the alternator. And depending on how long the alternator has been bad, you may now need a new battery, also.

im gonna have 3500 rms in my car soon. and want to upgrade batteries. i dont want anything stupid in price, but i want to give it enough power to work the way it should. what batteries should i get?
