battery draining problem

[SC boss]

have a newer optima red top and my car cannot sit for more than two/three days without needing recharged! Any idea of where to start to find out what is draining this damn thing?! Normally I am out of town and just unhook the battery until I get back home but recently I have been home more and leaving it hooked up and coming out to a dead or almost dead battery. Any suggestions are appreciated.

Get an ammeter, disconnect the battery, start pulling fuses.

I had a similar problem but i have a lightweight battery and it would not start if i left the car sitting for two days. I then started having issues with my shaker 1000 head unit with cd's getting stuck so i pulled fuse 56 in the engine bay till i got that fixed and now it could atleast go 4 days and it will start. Im pretty sure it could sit for longer but i try to start it often so i know my problem is the radio but now i dont know how to fix it either wire it different or something. And i have tried turning the radio off before i turn the car off but that dosent work. Maybe you have the same problem i dont know

Make sure the radio is turned OFF when you turn off the ignition, if using the Shaker sound system. It'll suck a battery dry within a few days or a week if you leave it on and just turn the key off.

thats the thing, its an aftermarket stereo system that worked fine for about a year. car sat, built the motor, put it all together and now something has changed....

If you haven't found the problem yet and you can't let your car set more than a few days without it draining the battery I would recommend a battery tender, I keep one on my riding lawnmower and it cranks every time.
