My 99 Nissan Sentra will not start. I just changed the battery, so it's new. I also changed one of the "cables" as it was corroded. The car is not turning over at all. No noise is being made but my radio & dom light come on. What could the problem be?

Has the battery been tested, it sounds like a defective battery.

this could be a problem in the power distribution box under the bonnet like a corroded cable or the vibration has broken it ,disconnect the battery and put it on charge overnight and see what happens in case the battery is just flat ,if still nothing after charging try a jump start in case it is the batery died as they can go all of a sudden .

were the cables really corroded sometimes even cleaning them isnt enough due to corrosion in the cable check for voltage at batt and at starter with testlight or volt meter

well if the altenator is charging it will run after getting a jump, you replied you put a battery charger on it but that dont mean the cold cranking amps are good or it could have a dead cell. I would have the battery tested for sure. If you didnt drive far after jump the altenator may be bad but having the battery charged and still does it tells me it is least likely. If the battery tests good the cables could be corroded under the sheath where you cant see. There are other reasons but from what you have posted sounds like you need a battery most auto stores test them for free (load test also)

You need to replace the terminals on the battery leads and clean the terminals on the battery, baking soda and water, along with a good scrubbing with a wire brush should do it. That could also work with the cable terminals. Check the power going to the starter and starter solenoid for corrosion also.

try the battery connections, i had same prob. it was the black one that was corroded and i replaced it, then a week later it wouldn't start so i had to change the red one. then i had to do the fuel pump. then the alternator. then the starter wires

replace your battery cables, the cables can corrode on the inside, turning a dark green color.
OR the starting solenoid and the wires going to and from it. that one small wire going from battery to solenoid might be your problem.

Locate the air mass sensor next to the air filter box remove it and clean it very careful. Blow it dry and vacuum all dust around it. replace air filter.

check your battery cables to see if the cables themselves are corroded and also check the connections where they connect to the vehicle that they are clean
positivecable will connect at the starter and the negative will connect to the engine some where.
if this does not help then have your starter tested to see if it is dragging. as it could be the armature or the brushes in the starter.
