Bought my first RX7 in 1982. Light Blue with a sunroof. I think I still have that tinted glass roof tucked away somewhere, sold that car in the early 1990s. In the late 1990s, bought a black 3rd Gen in Redwood City, Mazda dealership on the fourth of July. It was used had about 21,000 miles on it.
In really nice shape. Paid about $25K as I recall. Haven't driven it much. Was working in Silicon Valley living in Santa Clara. Eventually shipped the car to our condo on the Big Island shortly after we retired in 2004. Finally decided to sell the condo about 4 years ago. Shipped the car back to the mainland at that time, as we had moved and were living in northern Nevada. After 10 years living in Nevada moved back to California the edge of the central valley near Lodi two years ago. Brought that car with us. Its always been a Sunday driver and garaged. Was surprised at how well it passed Calif smog test. Recently it developed the infamous ODO disease. Been reading up on the gyrations of fixing this. After talking with a Mazda dealer in ELK Grove realized I was on my own on this project. Next smog inspection is due in Aug. would like to get the car ready for that. The odometer is definitely necessary. I have never pulled a dashboard. That is the most intimidating part of this project. The IC board looks pretty straight forward stuff. However I hope my hands and eyes can still deal with it. Been a long time since I worked on R/T units in the Vietnam war.

thanks to all for the welcome. not very skilled with posting pictures. besides the car needs a bath. I have pictures of the speedo and odo unit now pulled. That task done. Waiting for desolder tools to come from Amazon due here today for the rest of the task. PC board looks fairly clean, no blown caps visible at this point. C3 looks nominal. Scratches head. Wonder if there is some way to power up board while on bench to read the eeprom data in the ODO.

The manuals show a lot but I'm looking at a specific PC board. The wiring manuals don't go down into those weeds. However, there has been some work done here on other threads to document that level. I'm still finding my way around this web based treasure of RX7 info. I know I'm not the first. But thanks for the pointer to the manuals, I'm sure I will be referencing them in the future. .
