I have 85 GSL-SE and last week my car wouldn't start so I jumped it and it started and then I killed it and me and a friend push started it I took in the battery to get it test after I charged it for about 2 hours and the guy at autozone told me to clean the cables and that fixed the problem but today I left the lights on for about 40 mins and I went to start it and it wouldn't start but It will jump start. I have to jump start it every time I want it to start does anyone have any ideas what is wrong?

 

battery...nuff said

 

or on second thought...alternator?

 

Either the battery or alternator, I personally would get the battery load tested and check how many amps the alternator is putting out (a shop or dealership has the equiptment to do this). I perfer the find out exactly what is wrong before resorting to the "replacing everything till its fixed method..."

 

thanks guys

 

The thing is that when its running the battery gauge is around 14 volts so I was think that it was just the battery thanks guys
