My battery is draining by itself.....if i don't start my car for like 2-3 days the battery just goes dead......so I've replaced it and checked the alternator.....still the same. About two weeks ago my car was parked with the engine on when my lights started blinking and i heard something clicking somewhere behind the left vent. It did that for 2-3 sec. and then everything went completely dead. So now I'm stating to believe that the problem is one of the relays on relay block No.1(that's how is called in the Haynes manual).
Anyone knows how i could check those relays or find and fix this problem?
Thanks.

You should first check to see that your battery and charging system are working properly, your local auto parts store will do this for you if you don't have the equipment. Once it is determined that they are not the problem, the best way to find a parasitic voltage loss would be to remove the positive battery terminal and place one probe from your multitester or ammeter on the terminal and the other on the battery post where the terminal was. With the key off you should see a very small draw, usually less than one amp, for devices with memory such as the clock, radio, alarm if installed, etc. If your reading something higher than that, pull out then replace each one of your fuses one at a time, making note of the reading on your meter as each one is removed. When you see a sudden drop, make note of which fuse was removed and you now know which circuit your problem is contained within and can now find the short or the faulty device.

i did that and the power loss is in the dome circuit.......but how can i find what exactly is losing power over there?
