okay my vs 5l decides to have a flat battery sometimes but not aways.
i have put in a brandnew alternator, battery and upgraded all my ground and charging wires to 0 guage.

today it started after a few days no problem and ive started it a few times all day no worries, but tonight i have to use the jumper pack everytime.

and yes the alt light on the dash works and is not on. i know this because it was on before i changed the alternator a month back.

Do you charge it feom a proper charger after it goes flat, or are you just using the altinator?

ive done some reading and ive thought maybe the fusable link but it does start somtimes. and the alt is keeping the car running no problem for any amout of time. but its not enough volts to charge the batt

Get a multimeter and check current draw with key off

Just a quick suggestion,
Check where the Positive (+) cable attaches to the starter solenoid.
I was having the same sort of issue at one stage & it turned out that the bolt inside the solenoid had broken on the inside.
The bolt was still done up tight but it was loose on the solenoid cap.
I hope that helps.

Without properly charging the battery once it goes flat you will only be giving it a surface charge, this will eventually ruin the battery

What Bottlefed said, Check that. Same thing happened to me except mine would actually stall the power would get so low, then it would be fine. I replaced my ground and power cables from the battery all the way to the starter and it fixed it.
