Problem with 2002 Silverado

[bobcat]

knowing that your battery is 6 years old and you just killed it about 3-4 times, i would be thinking about replacing your battery anyway. killing a lead cell cranking battery is extremely hard on them and being six years old if you dont replace it youll be asking for trouble.

Thanks, I will keep that in mind.

I'll try to get by for a while since I have no money!

Sometimes when alternators lose bearings the brushes will make contact when lined up correctly and then when they get out of line they won't make contact correctly to charge correctly, which is why you see the intermittent function.  When the bearings get worse, it won't work at all and will have a total failure.

Good to know! Thank you!

a six year old battery in a gm is about the standard life . my bet is it wont be long , i'd change it at the first sign of a slow crank . So after you ran it for awhile I suspect it started running better . once the fuel trims adjusted . you are going to want to check the lower intake for a vacuum leak .

The engine actually ran good for me all the time, even when the bad alternator was in it. The only time it was running bad was when my uncle came over and put the new alternator in it the first time (I was at work). Later I put the battery on the charger overnight and drove the truck and it ran fine. And the alternator would work for a while, then quit working.

The battery is from Costco and I believe it's a 9 year battery.

9 year battery seven year ? maybe. once those things get pulled down a few times they never are the same .

Yes I think you're right- 7 year. You're always right when it comes to vehicles!
