help! nor you usual alternator question!
hey guys i just go back from the dyno and wile the car was being tuned my tuner told me the cars voltage was only at 11-12 volts wile makeing the runs.
my battery is new and for some reason when the car sits for 4-5 days the battery will drain close to dead.
is my alt starting to go out? the volt gauge shows past 13 when the car is running but i know the gauges are not so true.
if it is starting to die what kind of alt should i go with?
thanks guys.
oh and sorry for some of the bad spelling im tired lol.

sounds like a failed alternator, until you mention how it shows it at 13 on the gauge. the gauge is actually pretty accurate, i mean it would at least be clear its at 13 and not 11. so its possibly an intermittent internal alternator failure...interesting...
i see it as an alternator is an alternator is an alternator. so i'd just replace it with a reman, most come with a warranty and ive never had problems with remans from carquest n such.

well if its only charging at 12 volts its not charging at all. the pcm might not be sending the signal to charge, id look into that. i think the signal is PWM so a voltmeter might not pick it up. you might need a good scan tool to test it. also try to full field the alternator and see what the voltage goes to. should be like 16 or 17 volts.

the pcm part should be ok but the tuner told me about the low voltage.
if some thing was wrong wouldent the car being connected to the laptop wile being tuned
show it?

i went ahead and replaced the battery to alt cable with some 4ga wire and replaced the ground wire that goes from right behind the alt to the frame with 4ga.
ill clean the alt plug and im having a small power stearing leak and i noticed a little fluid on the plug so maybe thats the problem or maybe not.
its not like the alt wasent charging at all it just not puting that much volts out.
