i have an 87 n/a rx-7 and when i start it up the idiot/warning lights don't come on like they're supposed to. also, the seat belt buzzer, key reminder, and the horn don't work. does anyone know how to fix?

 

lucky bastard

 

You may be able to fix the idiot lights by resoldering, hmmm...horn i have no idea.....look up past threads for more answers the gurus always come through.

 

Sounds like both the warning light cluster and the cPU need to be resoldered. Search the 2nd Gen forum for "resolder*" and you'll get plenty of info.

 

Dittos all the above. The idiot light cluster should come on when the key is turned to on. There is a relay in the CPU next to your left foot, that should get a signal from the alternator to pull in, which in turn puts 12v on the idiot lights to turn them on. When the alternator starts putting out, the relay relaxes and the lights go out. See that the two wire plug on the back of the alternator is on good.

Also go to http://www.fc3s.org/ and download the 88 fsm and the wiring diagrams. Its a free download.

Cold solder joints on the CPU do cause the horn and idiot lights not to work as they should.

Also, go to this site http://home.rmci.net/panther/ where you will find any number of fixes for your car.

 

Good point, both problems may be related to the CPU. Resolder the CPU first and see if this fixes the warning lights as well.

 

oh, you can actually FIX your horn not working? I didn't feel like troubleshooting mine for inspection, so right now i have a house doorbell sitting in the console of my car...

 

"That ***** cut me off!" DING DONG...

 

Once I plugged that two prong connector back into my alternator, everything started working again

Probably isn't your issue, but JIC..
