starting issues

[nick585willey]

so i recently had a battery light on and it turned out i needed a alternator, so i put one in... the battery was less than one month old at this point.... anyways the last 2 days i went to go start the car and nothing, the door poppers worked, and then when i tried to start it fizzled out and the door poppers nor any power worked at all.... then the poppers and everything works all of a sudden... just no turnover like the batterys dead... but the battery shows 12.8 when its not running... and 14.4 when it is... which is normal battery voltage.. so i pop start the car and drive it somewhere and then turn it off and can start it right back up like nothing happened.... i find it has done this the last 2 days after sitting for a few hours but i have no idea what could be wrong... there isnt a click when i go to start it and its "playing dead" maybe my battery wires are messed up? theres no corrosion..

PLEASE HELP!

check the starter connections . there should be one heavy wire that is held on with a nut and another wire that is thinner and you just push in to a spade connector . the small wire is going to have power when the key is in the crank position . the other wire should always have battery voltage . if everything checks out at the starter and it doesn't crank then your starter is bad . also make sure your grounds are all tight and connected.

any chance you know where the starter and most of the grounds that i should check?
