June 12, 201213 yr 1999 Legacy Phase II EJ22 automatic With the car off and keys out of the ignition the back up light fuse has 12 volts to it - is that normal? I believe a number of the fuses do - heater fuses, etc - seemed like all of them had 12 volts. I was thinking they should only be powered with the car on or the circuit in use?

June 12, 201213 yr Fuse number 1 should only be hot with On or Start. Power for that along with everything here: Rear defogger timer AT shift lock control module Back-up light switch (MT) Inhibitor switch (AT) Hazard switch A/C switch Combination meter Mode control panel Rear defogger timer TCS off switch Blower motor relay Check connector Daytime running light control module Daytime running light relay FRESH/RECIRC actuator Hi-beam relay Keyless entry control module Power window and sunroof relay Seat belt timer Security control module Vehicle speed sensor (MT) Wiper deicer relay Wiper deicer timer Airbag control module Airbag control module Lighting switch Comes through the ignition switch. Some other things may be switched as well. Some fuses in the dash panel are also hot at all times.
June 12, 201213 yr Author Fuse number 1 should only be hot with On or Start. Okay - so I have a solid 12 volts at that fuse with the car off,key out - that's a problem? What would cause that? Bad ignition switch - that's interesting. The "heater fuses" (there are two of them i think) - both have power with the car off/key on as well...heck i think almost all the fuses do?
June 13, 201213 yr Author Wish I would have thought of this earlier but I tested my 1996 Legacy and those fuses have power at all times, even with the car off and keys out of the ignition...weird, I didn't know those fuses were powered at all times? That car runs perfectly so I guess it's normal for the fuses to always be powered...seems really strange to me.
June 13, 201213 yr I'm scratching my head too. Wire diagram makes it look like they should be hot only in Start/On. But looking at it, the hazard light circuit is mixed into all of that as well, and THAT works without the key... It's possible I'm reading the diagram backwards, or just missing something, but I don't see a power source for any of that other than through the ignition switch.

June 13, 201213 yr Author some other folks are saying that "no" they sholdn't work either....and made the point that if the fuse is powered those things should work with the car off, key out of the car - like blinkers. i don't know - but it's the same on my 96 so must be the norm.
