I just put in a new alternator and battery a week and half ago. now i can't start it, just clicks. My battery was jump started and my car started and died after five mins. is it a wire or fuse thats bad or does my alternator or battery have a defect??
You probably have a battery drain from a defect. circuit. Just put a
test light between the ground of the battery and the ground cable. If
you have a drain problem, the light will go on. Then you remove the
fuses one by one until the light goes out to isolate the circuit. A
electrical wiring diagram will be appreciated.
I would say it is the installers fault and that the alternator is
probably working fine, but the alternator is either hooked up wrong or
has a broke wiring harness or the belt is under driven or this is the
wrong alternator for your vehicle. or the best answer is you have a
short somewhere causing the charge from the alternator to not reach the
battery. In other words the pathway is broken. There can only be a few
answers to this question. Something is broken/loose(wiring) /installed
wrong/or the wrong part. Try the z net from autozone. It will give step
by step instructions. You need to include further information of the
vehicle(year/make/model/size engine/ if you want specific informationPull the pos strap off of the battery when the car is running, if it
dies and you know that the alternator is good you could have a short.
That could be what is killing your batteries.
Is your car
killing batteries overnight? Could have a short somewhere else and that
short just put more strain on your alternator.one way to see is to start car with nothing on in the car
an remove hot lead from battery car should stay running if it do turn
head lights on car should die Resistance in the wiring due to corrosion or poor ground. Sometimes
theres a regulator that controls the voltage and amps within the
alternator that is defective
Unfortunately there is no real easy way to find the issue here. Firstly, is it taking charge? The first and easiest option is to replace the battery. First, just have someone put a meter on the battery which will indicate if the battery is no good. At that point, if it is looking okay, we would put our sights on the alternator. To see, with a new battery or one charged, start and run the car. If it still dies out so quickly you will probably have it brought to a mechanic.
Oh, and FIRST step is getting that battery exchanged. That is most important!!
When my cutlass did this I first replaced the battery then alternator but it still kept getting dead batteries. The fix was it needed a new starter.
