If it still goes bad after you replace the battery, you will need to isolate the problem. It could be bad diode(s) in the Alternator, but it could also be something else.

If you don't already have one, I would get a DC AMP Clamp Meter (around $50 from Sears) connect it and take note of the current draw reading. Then start pulling fuses one at a time until the current draw goes away. Once you have isolated the fuse that made the draw go away, find a wiring diagram (there might be one here http://www.bbbind.com/free_tsb.html

Then reinstall the fuse and start unplugging items on that circuit until you find the culprit.
hope this helps!

Have the battery tested, many times when u run the battery dead it ruins the battery, if the battery was good u should have been able to listen to the radio for at least 4 hours and still start the car, chances are the battery is no good. Kragen auto and others do this for free. Never assume u have a drain until all other poss are checked. Let me know what u find, I am fairly sure the battery will test bad.

98.3hombre battery went dead after a jump it wont start


double posted, why?
JUMPS OK
AFTER JUMP WORKS AND DRIVING, AND STOP AND KEY OFF
IT WILL NOT CRANK.
did i guess right?
that means ,
check all fuses first. even the alt fuse (large)
1-battery bad? #1 top failure all cars.
2-Charge system bad. (is the charge/ batt warn lamp glowing when running car, bingo.????

3-or phantom drains. (if no crank just after stall then it not this) if drains while sleeping yes.

the tests are easy, a dirt cheap voltmeter
13.3v to 15v running is good charge system.
if 12v and falling not.

if the battery is bad, the charge system can shut down, so, the best practice is to try a know
good battery out of 2nd car, do you have battery to barrow, this is TOP CHOICE< not thinner wallet.

if the good battery fails then the charge system is failing (note I said system and not a part)
or the belt missing or slipping to the alternator.

btw the 4.3L PCM runs the alternator
PCM is engine brain.
btww, same true 2.2l engine.
the regulator is in the PCM.

so is the charge/bat lamp in cluster
on key on, lamp test
the jump start it , it runs
does the charge./batt.lamp go out.
id be all over that lamp, costs nothing to look.

Battery dead - car will not start or be jumped started


Change the battery. Newer batteries sometimes go all at once, and are so dead even a jump start won't work. It has happened to me twice. Once you put in the new battery check the alt output with a volt meter should read about 14.5 volts at the battery. If it does problem solved just reset the clock, radio etc.

Sounds like a battery to me. The cold doesnt drain the battery it just makes it more difficult to produce enough energy to crank the car. If the battery is weak already, the cold just makes it worse. Replace it and move on!

I filled the gas tank up on Sunday and went to get back in and crank it and it wouldn't start. I had to get it jumped off. On Monday it started and ran fine. On Tuesday, I went to start it to go to work...


When your car battery goes dead for no apparent reason, Occasionally something is drawing power that’s not of your doing. This is a parasitic draw, and it can cause the same result as leaving the headlights on. To read more on this type of battery drain please visit my blog
