Draw on battery when car is off killed battery. Options

[nitemare]

Well, after replacing battery- 1 week later- car is dead. Last 3 years I went thru 3 batteries and 3 alternators.

Now - Im not replacing them anymore. Obviusly, there is something wrong which is killing the battery and alternators.

So, I removedfuses for the amps. I disconnected the viper alarm. Volt meter still lights up - meaning there is a significant draw from battery when car is off.

Its at mechanic. Only thing left might be the radio (alpine). But, never seen that draw enough power to kill the battery.

Any ideas?
