I have a 2006 Camry with a battery drain issue. I disconnected the negative terminal & hooked up my test light & started pulling fuses until the light went out. I pulled the D.C.C. 30 amp fuse from under the hood & the light goes out. I reinstalled & started pulling fuses from the inside. The ECU-B & Radio NO. 1 fuses pulled together makes the light go out. If I keep the ECU-B fuse in & pull the radio NO. 1, the light gets dimmer but still on. If I pull the ECU-B & keep the radio NO. 1 in, the light stays the same. I un-plugged the radio & the light dims just like pulling the fuse. Its pulling about 10v using my fluke meter. Any ideas before I take it to the stealership?
