93 RX7 tach/speddo
 

My 93 RX7 tach and speedo both stop working at the same time. It is intermittent, sometimes they work, sometimes they don't. Any idea's on where I should start in fixing the problem. Thanks

Start by downloading the Factory Service Manual for the link in the 3rd gen FAQ thread. Go to the respective troubleshooting section and have at it.

Start by checking the fuses.
