hey guys, any help would be appreciated.

Today as i was driving, i noticed my voltage meter on my 84 GSL would go down low, then a few minutes later it would go up to normal. Then it would go down, then up. AFter awhile of driving, the voltage meter went to zero, and my lights wouldnt work. the car still ran, but the battery seemed drained out. I got home, and boosted it, and it started again, but then the voltage went down again. I think my connections are on properly to the battery, so could it be the alternator?

by the way, my battery is brand new, so that cant be the problem.

please help!

 

New stands for Never Ever Works. No but with the car running you could disconnect the battery, and see if it still runs if it does then the alt isn't bad, if it dies then the alt is bad. at least I think thats how it works. that or if there is an auto parts store near then you could have them test the alt, I know they do it around where I live, free.
