Battery draining completely within 15 miles of driving
Recently the battery in our Subaru Legacy started draining all of its juice for no apparent reason. The first time it happened, I assumed that the battery was old and wouldn't hold a charge anymore. I bought a brand new battery which started and ran the car. However after I drove the car for about 15 miles, that batter went dead as well.
When it comes to automotive problems, I am fairly mechanically inclined but as soon as you add an ellectrical problem to the mix, I become progressively dumb and dumber.
Re: Battery draining completely within 15 miles of...
I had the same problem on my NEW Forester, dealer told me to check the litttle switch set far down on the top of the steering column. I had accidently turned it on while cleaning the car. It turns on some tiny lights that are used more in Japan and not easily noticed unless you are looking for them. Sure enough, that is what caused my battery to drain multiple times.
Not sure if it helps but it's worth checking just in case.

have you tried to pull the fuse from the alarm. is the alarm a factory or after market. if it is a after market alarm look under the dash on the drivers side there will be the wires to the alarm just pull the fuse. the other thing to do is disconnect the battery every nite
try to jump start your car see if the interior lights are real dim headligjhts maybe you drained your battery too much or burned your alternator also check the fuse for your alternator see if blew hope this helps also check the fuse for your battery and check make sure the terminals are tight not dirty
your alternator has died i would replace it and have your battery checked or replaced .....when your alternator quit working it drained your battery right down until it was dead it might not hold a charge any more....i would replace them boath
Did you bench test the old starter? Did you bench test the new starter?
the battery may appear to be good, but try jumping it with another battery.
check the cables.
use a set of jumper cables to bypass the battery cables, this is a quick way to trouble shoot the cables.
hook red to the start solenoid an black to the engine block.
Try these and let us know how you make out
hope this is of some help.
not sure if this will help, but I recently changed the engine in my subaru and changed battery + starter also. Would start but then not restart once warmed up. Turns out the engine ground got forgotten, had that hooked back up after banging my head on a wall for a week and it runs like new
No. You have a Bad Connection with the Battery and the Battery Cables. Remove the Battery Cables, Get a Can of Coca Cola and pour onto the Ends of the Wires that Connect to the Battery. They should Fizzle like Hydrogen Peroxide. This will eat away the Corrossion on them. Replace the Battery Terminals and Tighten. Also, Check the Tension on your Belt. If it is even a Little loose it will not allow the Alternator to Recharge The Battery while Driving.
