Re: Question re: Radio security codes

Jeff:

I think I have seen something similar for about $15-$20 at Imparts, or
you can try to build your own.  It shouldn't be difficult :-) However,
the 9V from the battery can flow back into the car's electrical system
and possibly defeat the purpose of disconnecting the main battery.  If 
the radio and the lighter are on the same fuse, you can remove the fuse 
AFTER connecting the lighter battery and that should keep the circuit 
isolated and the radio happy.
