Drawing current from battery

[Gurney]

The battery in my pulsar went dead and seeing as it was old, I replaced with a new one. The car was then parked and not touched for a day, then when I went to start it the battery was completely dead. Took it out, recharged it and tried again, was dead within a day yet again.

Clearly something is drawing current from the battery but im not exactly sure what, my uneducated guess would be the amp. Never had this problem before and not familiar with the eletronic side of cars.

Thoughts and suggestions as to what it could be?

Im no mechanic but put an amp meter between the neg terminal on your battery, and the neg lead. Check your amp draw rate.

Remove power to your amp and see what the draw rate is then. If its not your amp, do the same thing by removing a fuse at a time. Once you've found the culprit, go from there.

To flatten a battery in a day you would need to be drawing 2-3amps, put a ammeter between your neg terminal and neg lead and pull fuses untill draw goes away, locate your fault from there.

Amps are notorious for doing it, as are head units, immobilisers and interior lights

The immobiliser has been disconnected since I broke the remote for it, the head unit doesnt like to turn on by itself anymore when I turn the ignition on so im pretty sure its the amp. Might try disconnect it and leave the battery hooked up and see how its goes, lets see if I ever know how to disconnect it rofl >_<
