According to my parents the car died when they tried to get home. I figured it was the alternator cuz it lost battery juice. The weird thing was when I check it with my DVOM it read 12.28v. So I figured lets just get it tested to get it out of the way. Checked out fine. So I put it backed it and checked all the grounds to it and check the voltage again and it said that it was 12.28v still. So I get it the car and try to start it and it doesnt start. Didnt make no buzzing/clicking/lack of power noise. So I hooked up my DVOM to it and got it the car to see what would happen. It read 12.20v. Okay, so I turn it to the just on, not even fully starting the car yet, and the voltage reading went from 12.20v to 7.00v and continued to drain. I turn the key to off and it started to recharge its self again. Now I'm stumped right here cuz there is no corrsion on the battery cables and the ground on the alternator is good. There is no blown fuse of the in the engine compartment fuse box. Can someone guide to what might be the problem cuz I cant figure nothing out right now. I truely frustrated I use my CB to cruise to work everynight.

Do you even hear a click when you turn to the start position NOT on. Try cranking it see what happens. The voltage goes down because the starter drains a lot and you have the fuel pump priming. SHouldnt be much though. The starter is what draws the most current. As I said try starting it and report what you hear and what happens not just key in the on position.

Chances are, your battery is toasted. A battery at 75% charge holds 12.4 volts. A 100% charged battery is 12.6.
A dead battery is 12.2v.Originally posted by sweet91accordComment

My oberservations when I attempt to turn it on, it makes a clicking noise then fades away due to the lack of battery juice. I bought the battery 4 months ago.Comment

I'm guessing when ur parents were driving, they hit the brakes and all the lights began to dim, untill it completely shut off?.. that's what happened to me.. it was the battery. If you got another battery u can use from another car to see if it will start up, try it. Then use the volt meter to see where the charge stands. If it's normal. then the battery is ur problem.-:¦:-

Its hard to tell if a battery is dead just by putting a meter on it. You need to put it under load. It shouldn't go below 9V.Originally posted by foamypirate
If you have a VAT-40 load tester, (They are scary with a bad battery. Some will start to smoke haha.) Which I doubt you do.
Either way the car should be able to run with the battery disconnected. I'd say look at the alternator.wat?Comment

try jump starting it first, then if it works, unplug the negative battery, if the car dies then its ur alternator, if it doesnt then it most likely is ur batteryComment

I was referring to dead as "no charge."Originally posted by C91BLX7
Carbon-Pile Load testers are fun though! Especially when you have a bunch of auto shop students who have no idea how to use it, and it starts to beep at them and they freak out, lol.Originally posted by sweet91accordComment

Thats pretty much what happened to me. The starter was old as hell and drew so much power it fucked the battery.Originally posted by DarkRidgeRacerI dont know how you knew it Nail but that was it. The starter was the problem. Thanks Nail!!!wat?Comment

I've worked on starters but the sypmtoms were different from most of them that I have worked on before. At least that was a new experience to me.Comment
