I've got this car that does not start and seems like a battery problem at first, when you turn the key it doesn't turn on and it sounds like the battery is fading, but when i chek the voltage it show above 12 volts, so the battery seems to be ok, I checked the starter voltage and it shows above 11 volts, it starts if you charge it with another car connected to it, I've been told it's the starter the cause, how can I be sure if is one thing or the other.
Lately I've got some trouble with the battery discharging because a ligth problem and I disconected it a couple of times but it worked just fine when reconected.
Thanks in advance.
