Problem with car battery staying charged

[hiryux]

I have a stock 95 240sx and Im having trouble starting up my car. I thought it was the battery and I took down to walmart and had it recharged. I drove around for the day and it started up fine but then I was working on it today and it started to get really drained and eventually stopped. Then my friend jump starts the car and it will run fine. I turned off the car and tried to start it up and it wouldnt. Does it sound like I have an alternator problem? I dont own a voltage meter so I could test it but I wanted to get your guys input on it. Thanks in advance.

get the alternator tested at an advanced autoparts or something like that.

If it was running and then bogged down and quit, then yes it is either a problem with the alternator or it's wiring. You really should own a multimeter. They're cheap, and they're almost as essential as a 12mm socket wrench.
