How do I Disconnect? Trial & Error

How can I go about disconnecting the power antenna, power seats (dual), and the radio from the fuse pannel? Or anywhere else that would disconnect from the system..

I want to go through a trial and error process to find out which of the 3 is causing the fuse to blow every time KOEO..

Is this easy? Do I have to take out the dash.. Or a quarter pannel... I'd like this to be a simple job.. But I can only hope.

Thanks and hope to get some advice soon.. Having no radio is really starting to annoy me.

Radio and antenna are on fuse 11. Power seats are on a circuit breaker in position 12 on the fuse panel. If fuse 11 is the problem it relates only to the radio harness. Power is on the Y/BK wire from the fuse to the radio and through a 2 pin gray connector to the power antenna located behind the radio. Remove fuse 11 and connect a voltmeter or test light to the two fuse terminals and disconnect the radio and antenna behind the radio. With the key on, if the light or meter shows voltage present at the fuse there is a short to ground in the Y/BK wire between the fuse and the radio connector and so on. The basic procedure is to disconnect whatever devices are on the circuit as well as whatever connectors are in the circuit and checking each section of the wire from the fuse box to the device until the the bad section of wire is found. In this case the only connectors are to the radio and the antenna, both are behind the radio, so remove the radio and go from there. Should be fairly easy.

Sounds good..

Fuse 11 blows every time KOEO..

And the seats just plain don't work. I'll try getting a new circuit breaker for it and try it out some time this week.

The Bird is being painted to won't be able to try anything out for a week.. I'll come back to this thread though.

Thanks for the good help.. Knowing that this shouldn't be a huge job makes me feel a lot more confident about my car haha.

Okay so I just got the car back today..

I went to work and got a new circuit breaker to see if that would fix the seat issue..

Nothing.

I guess my next step is to check the wiring harness.. correct?

I haven't gotten around to the radio but I will once the finale things are done (wheels, lowering, clutch)

Yes. Disconnect the connector at the switch and check for 12v at the BK/W wire and good ground at the black wire. The switch is often at fault and it needs to be checked for continuity which you can do by connecting one ohmmeter lead to BK/W position and probing the other terminals as follows:
1. Individual switches
Front: Y/LB up R/LB down
Rear: R/LG up Y/LG down
2. Joystick:
Forward R/W
Rearward Y/W
Up R/LG and R/LB
Down Y/LB and Y/LB

I've fixed the problem with my radio and antennae.. The wire going from the power antennae switch had been clamped in between a screw holding the driveshaft in place and had been squashed, exposing the wire touching the metal thus shorting the circuitry. Freed the wire and used electric tape, replaced the fuse and it now works, stereo and power antennae.

But I still have the seats to fix..

Congratulations! Did you use that new short finder you ordered or did you eyeball it?

Thanks! I couldn't believe my eyes when the fricken deck lit up for its first time. Watching the power antennae follow the switches command felt pretty good too.

Actually, I found the crushed wire by trying to use the short finder, which didn't work.. Haha.

I still don't know what to hook the 2 clamps on to?

I have another question I need help with in terms of my stereo.. I made a new thread for it so if anyone wouldn't mind heading there to help me out that'd be awesome

Thanks
