I Need Help!! pls!

i owned a 98 monte carlo z34 3.8 for about 4-5 months...my problem started about a month ago...
-'anti lock' light came on during driving
-window was hard to roll up/down
-shortly after 'volts' came on
-i stoped went to the store came back out and it didn't start again

jumped the car and drove it home...tought it was the battery so i replaced it...worked fine for about a day and it did the same thing again...took it to the dealership they said it was the alternator...had that changed...was running good for a couple of days...when the same thing happened again...found out that the wire that goes to the alternator was broke so i changed it and the plug that goes with it...ran great for about 2-3 weeks...two days ago started doing the same thing again...
im out of ideas...read somewhere on the net that the PCM could be the problem...and another thing is that it only has around 5V on the alternator...and i heard it should be around 13V...
so please help...any ideas are welcome

if u need more detail ill be glad to explain more

thanks

a possibility is that your alternator killed the new battery, and the now dead battery killed the new alternator.. I had that happen to me. might be somthing to look into, get autozone or someone to check both the alt and battery.

Hey just realized where I knoew your name from! My monte! I would go with what was said on there!
