For my 86 I've been looking on all the automotive reference sites but have no luck in getting a wiring diagram to my clock. It's amazing how few diagrams are available for this car. I'll buy a mazda book eventually but i'm curious if anyone has a wiring diagram for the clock or any links to some help. All my under dash fuses are good but that's as far as i can check. All the warning lights on the center display work just the clock is inop.

 

Interesting... I looked through my Haynes Manual and couldn't find the clock wiring under the chassis electrical section. We will likely need the GSM in order to find out.

 

The bezel is deteriorated anyway so I could probably take the clock out and check the wires on the back. There should be 3, all time 12v, accessory 12v and ground right? maybe a 4th for illumination. As long as all the signals are there the clock should work.
