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.
