    Just curious. My '89 FI AutoTrans died on me this morning and I happened to have a spare module (Igniter J 207) and when I switched to the new (actually, used but pre-tested as good) one the car started. Any way to test the old unit out of the distributor, and has anybody opened one up to try a repair/re-build of the module?
    After the first one failed on me a few years ago I tried to get one through a parts house, but it was a Saturday on a long weekend and they wouldn't've even been able to order one 'til the following Tuesday, and it listed for about 120 bucks. I hit a you-pull-it JY and got one for $5. I've since grabbed one every time I've seen it at a JY, and that's how I happened to have one in the glove box, and I know there's at least one more around somewhere, I believe in a toolbox in the garage.
    Do the later model AutoTrans models have the same module, or are they all the one that's part of the disty itself?
    Thanks.

        Carb Festys are completely different and 89 auto Festys are a transition year but (solely for EFI Festys) I was told that rebuild kits for in-dizzie camshaft position sensors are not (and never have been) available and that you have to buy a complete new dizzie or have the old one rebuilt. On that note forum member Bobstad paid "full freight" at NAPA for one of these last year ($400 +/-) and that has prompted me to scour all 90-96 Mazda cars at JYs for these elusive (and now known expensive) dizzies. Whatever type of dizzies were used on EFI Festys are also common to many other Mazda pre-OBDII cars.
        It didn't bother me in the slightest at the U-Pull to have to fork over $10 for a virtually new dizzie plus cap and wires (wasn't even dirty nor the aluminum dulled) that I scored off a 94 MX3 B6 16 valve engine last spring.

            +2 on re-posting the original wiring diagram. Technology is a fickle mistress.

                  Any chance you could post the diagram of the disty tester again ?
