Electronical fail (plz help fast!)

[Reign]

Sigh I know I'll catch some flaming for this so lets get past it while we can

I am an Idiot!

There. Now, Here's my problem.
I was connecting an LOC to my mazda 3 (the 09, not turbo'd) when I accidentally hooked the wrong cables together. This wouldn't normally be a problem but at the time I had already removed/replaced the terminal on my battery to test my amps power connection and had forgot to remove it one final time before placing the final audio cables.

What it boils down to is I spliced into the radio constant cable (the one that keeps power to the radio even when the car is off [orange/white or something]) and then there was a sizzle from the wires (not from the head unit) and then some things stopped working.

Here's a brief list of what I've noticed.

Cabin lights don't turn on.
Door open light is on, all doors are securely closed.
gauge cluster (tec, speed-o, gas, heat) all act funny when the key is placed in the "on" switch but work fine when the car is running/moving
radio is getting no power. No clock, not radio, no illumination
keyless entry system doesn't work

And that's it. everything else (gas, break, clutch, pwr steering, headlights, turn signals, etc etc) work fine when the car is on.

But what's puzzling is that none of the fuses are popped. I checked the ones under the hood and in the cabin, and they all seem fine. I think I might be missing one that protects all of those things or a master fuse has blown but I'm not sure.
I have no idea what happened and I need some ideas fast!
Any help will be VERY appreciated!

I'm not really an electronics guy, but aside from the hidden fuse possibility, could you have shorted something & sent a spike back to the Body Control Module (or whatever Mazda calls theirs) that could have disabled random functions?

Someone with more intimate knowledge will chime in, I am sure.

Thanks bill

I looked up what the BCM is and the idea of it being shorted or broken sounds pretty spot on, but I don't know where it is or how to check it. I've googled around but can find nothing.

anyone else have any ideas?

I can check the wiring diagram for it tmrw at work and see if those circuits all connect somewhere/somehow, be it a splice, fuse, breaker, fuse link, bussed ground, what-have-you and let you know what I find. Did you just look at the fuses or did you actually test em with a light/meter? Just in case you didn't know, fuses have a small area of exposed metal on the backside that is accessible when the fuse is installed. You can poke the backside of each leg with a 12v test light and get an accurate result in just a sec, do a whole fuse panel in 20 seconds with no guessing if something might have been missed. Good Luck with it, will check back tmrw.

Thanks a ton I hope to hear from you today, we're trying to sell it and I need to know what to fix before putting it up for sale.

C.T.B.B has a good point for easy testing. Check the fuses for power on both sides. ( the two bare metal openings on the fuse ) .

I just experienced the exact same problem as the original poster, but I wasn't working on the radio or anything. I just started my car and the radio was not working, no radio display, no interior lights, door-ajar was on and gauges would sweep when I start the car.

Couldn't find a blown fuse, and I was dreading a repair bill... so as a last resort, I disconnected the battery, walked away for about an hour, reconnected the battery, and everything is all better! I guess that's how you re-boot the car!
