I finally got around to investigating a nagging battery draining issue I've had for a while. Using a test light approach I discovered that my "CTSY" (courtesy) fuse is the problem. My question is how do I pinpoint the issue beyond here? I've checked connections on the cigarette lighter and dome lights. Should I check the relays? If so does anyone know where they are located? As you can tell my wiring knowledge is limited. Any insight is appreciated.

Thanks in advance,
