battery keeps dying Options

[diegohiga]

I did a battery test and i got good results i got a yellow top optima battery i think is less than a year old so i doubt is bad. Just installed a new alternator as well.
What could be draining the battery and how you find out whats causing this?
I always had a system with a capacitor dont know if a bad capacitor could affect that?

Thanks

Hey search google for "Parasitic Draw Test" and go ahead and click on EricTheCarGuys video.

This is a simple test to show you how to find out which circuit in the car is draining the battery when the ignition is not on. If you don't have a multimeter/ammeter you can pick one up at walmart for around $11 for a analog one or about $20 for a digital one (note: These are cheap, BUT they get the job done and they do last a long time if you use them properly). Im sure theres other places that sell them for cheaper but walmart was the cheapest where I live.

Plug in the positive lead to the "10A" jack on the multimeter/ammeter
Plug in the negative lead to the "com"/"ground"/"gnd"/etc. jack on the multimeter/ammeter
Set the dial to 10 Amps
Attach the positive lead to the negative battery cable of your car (you can use plastic clips to secure them to the cable)
Attach the negative lead to the negative terminal of your battery (again plastic clips will hold the lead to the battery terminal)
You should see a reading of how many amps your car is drawing when you're not using it
Open your fuse box under the hood
Use the fuse puller to start pulling fuses out one by one and replacing them if there is no change in the reading
When the reading drops dramatically, you'll find which circuit the draw is from (there can be a draw from multiple circuits so if one fuse doesn't drop the draw to near 0.0X you have two circuits to search through to find where the drain is coming from)

Good luck!

Also I also have the same problem and i have yet to find where my draw is exactly. I know it is in the dome light circuit, but I'm not sure what in the circuit is draining my battery. So in order to drive around and not have to disconnect my battery every night.... I pull the dome light fuse out and leave it out until I start searching for the draw again.
