Pontiac Problems? Ask a Mechanic for Answers ASAP
good evening my name is ***** ***** I will assist
do you have a volt meter to do some tests??
can you get one?? we need to do some voltage checks to find out why the system is acting as it is. guessing is not an option as we need information to get you an answer
it will not read charging system voltage
ok, I will be here for a while.
ok, what is the voltage of the battery with it not running
use the dc volt scale.
battery is dead. it needs to be 12.6 volts fully charged. at this voltage, no systems in the car will work as they need at least 12 volts or better. the battery is most likely internally shorted. the alternator will never work as well without sufficient voltage. remove he battery and get a new one.
you cannot charge a shorted battery no matter how long you charge it
trust me, it is no good. they are parts people and not techs at all.
ok, did you install it??
ok, what is the voltage at the battery with the engine running???
ok, what kind of alternator???
check one last thing. the big fat wire at the back of the alternator, check that for the same voltage
ok, I had a couple of them bad out of the box as well.
if you have voltage at the back of the alternator, then you need to remove the alternator and retunr it and get another new one. have them test the new one before you leave the store
with the voltmeter as I stated. put the black lead to the negative of the battery and the red lead to the wire on the back of the alternator
dc voltage with the leads as I told you
