wat does ctsy stand 4? something on that circuit is draining my battery, any ideals?

 

That's the courtesy fuse, it's for the interior lights and cigarette lighter and such.

 

I think also the stereo. Lots of stuff is on that circuit, crappy that it's such a widely used circuit...

install your own stereo? perhaps cd player memory? (shouldn't drain a battery in less than a month, but...)

maybe a mod will be nice enough to move this to the electronics forum, trickster there is really good at this type of thing.

 

meant for the bulbs up under the dash that illuminate the front floors, but also many other lights and things are in the circuit yep

good luck
