Battery drain seems to be a short somewhere in my electrical system

I have replaced the battery with a new one three or four times and the same symptoms start occurring after very short time. There seems to be a short somewhere in my electrical system and I think that it is being caused by my clock-spring. So my question is, could my clock-spring be causing a short that is draining the battery?

Hello,

No, The clock-spring provides ground to the control side of the horn relay. Power is provided through fuse #42(15A) in the under the hood fuse box. This fuse is hot at all times, so battery voltage should be present all the time, even when the ignition switch is off, through the clock spring all the way down to the horn switch. But if there is a short to ground fuse #42 should blow, protecting the circuit.
What you need to be looking for is something that stays running when it is not supposed to be. You need to look for a short to power making a circuit where one shouldn't be and draining your battery that way. I have included a link for you down below to go to:

The battery isn't draining overnight. When I pull in I can still get up in the morning and turn the car on and it will work just fine all day as long as you don't leave the doors open with interior lights on for more than five minutes. The first time this happened I took the battery into Merle's Automotive where I had purchased it and they gave me another one under warranty the second time I brought it in I asked if they could charge it up and the guy behind the counter said no we can't because the battery is damaged. And I said what do you mean damaged he said it's swollen and that indicates a bad cell or cells within the battery. He said he would go ahead and exchange the battery under warranty but this would be the exchange because the battery was not at fault, it was my van.
The battery that is in my vehicle right now is the fourth battery that they exchange and would not exchange another one because it wasn't the fault of the battery.
They are correct in saying that the battery is swollen because that is what happens when it starts to go bad. When I put a smart charger on it it says that I have and internal short. But if you unplug the charger and then plug it back in it doesn't say anything and starts charging the battery.
Like I said, you won't notice anything different about the car or the battery until one day when you go to start the car up after leaving the doors open for just a few minutes like you have done a whole bunch of times before with no problems, the car won't start because there's no more cranking amps and putting it on a charger only gives you enough juice to start the car but not enough life left in the battery to operate anything in the vehicle for any length of time. I can go all day getting in and out of the car and it will start up with no problem. Just can't leave the interior lights on. So now that you've got the long drawn-out version of what's going on, what is destroying the battery?

And yes I've had the alternator checked out and the charging system and everything checks out okay.

Hello again,

That sounds very weird about the battery. They either have a bad cell or they don't. They usually get bad cells by not having enough electrolyte in the cell and it goes dry. I was looking through the lighting system for something that could be causing a draw on the system and came across this. Please see if this might be causing the problem. I have included it in the diagrams down below.

Thanks,
Alex
