Let me preface this by saying I'm an extreme newbie. I've wired eight models before this one, but I have either been following LED kits or told my local store what I wanted to do and had them hand me what I needed for the circuit.
So, I've parallel-wired a set of four LEDs into the roof/ceiling of a model I've built. I assembled the circuit that I've drawn in the picture (except that I have the resistor on the positive lead and not the negative). The LEDs came in a kit that had resistors rated for certain voltages. I'm using an A23, 12v Energizer. I've used the same LED kit in other models with no problem (sometimes even with 5 LEDs).
This one seems to drain the battery exceptionally fast, even when the LEDs are not on. I put a fresh battery in the model last night, switched it on for thirty seconds to test it. Today, I switched it on to admire my work and the LEDs were very dim. Tonight, the battery is dead. The whole thing has been switched off pretty much the entire time. That's the second battery this setup seems to have killed in as many days, with it "off" almost the entire time.
Now, my configuration is a little different from my other models, largely dictated by the layout of this particular model. I've checked to see that none of my joints accidentally touch, and I have no loose solders (a fresh battery shows nice and bright, but I hesitate to leave it in there because I have no spares and I'd have to take it out of another model).
It was my understanding that the order of the elements doesn't actually matter...have I unwittingly done something wrong, causing the battery to drain even when the Leds are not on?
