Electrical Gurus: Need help trouble shooting electrical problem
I currently do not have power to my stereo system, acessory gauges, clock, power outlet, and power mirrors.
How this problem all started was, I went to replace my fog light switch with one from OTRATTW and I didn't turn off the battery when I took off the connectors to the switch and they accidentally touched for a few seconds and shorted; causing this whole mess. The switch and fogs were drawing power from an accessory slot in the fuse box under the dash. The AM1 and AM2 fuses in the engine bay were blown as a result from the short and I have replaced those and everything is working fine now except my clock, stereo, gauge pod, and power outlet, power mirrors aren't operating. Currently there is no power at the 7.5 ACC fuse slot beneath the dash. I believe this slot powers all of those accessories and I need to find where to trace the problem. I know this was a dumb mistake on my part and now I am paying for it. :(
Here is an image of the fuse diagram I got from a member on the blue room. He said most likely, the W-G wire (which powers the 7.5 ACC) from the ignition switch to the fuse panel is blown. There was power at the ignition switch to the W-G wire which I tested and there was none at the 7.5 Fuse so I thought the whole wire was fried. I replaced the wire but that did not seem to solve the problem and now I am stuck. Please advise of any ideas on what else I could troubleshoot. Thanks

I would pull every fuse systematically one by one, test replace and go to the next one. Also check the box to the left of the driver inside the cab.

I already pulled and tested every fuse with a multimeter to make sure they weren't blown. I tested all the fuses in the engine bay and the fusebox beneath the steering column.

I don't know where the fusable links are without diving into the schematics but that would be my next step.
Have you tried continuity testing from one end of the circuit to the other?

Which slots (empty or add-a-circuit) on the Driver side/under the dash fuse block did you use for the Fog light and Switch? For the power outlet, is 12v or 115v that is not working?

Thanks for the diagram Nestor. Actually, typo on the fogs, I meant my CCFL lights which were powered by the bottom right slot next to the 7.5 ACC fuse. Both do not have power coming to them anymore. It is the 12V power outlet that is not working, my FJ doesn't have the other outlet in the back.

Here are more diagrams.
Check the DC SKT Relay where the 12v power socket and the 7.5A ACC are connected.

Where are those relays located exactly? Is it by the fuse panel? Also, what is the best way to check if the relays are still working?

In the back.
Here is the front of the under dash fuse block
.
Check the circled Fusible link 30A Power, it is also feeding the 7.5A ACC.
Attached is the full (2007) FJ electrical wiring diagram.

The 30A fuse is not blown. I still need to check the DC SKT relay but I am having trouble finding it.

I havnt had issues with the fj so I dont know much on the electrical but is it tripping a code on your dash??? You may have surged the brain and need to reset it??? Idk Ive had issues with that before because the systems are all multiplex now cut one wire and half the electrical goes out lol.
