I think I FINALLY solved the reset problem. After rechecking all the wires via wiggle test I decided to pull the Link and do a thorough inspection of the solder joints. I found a hairline crack using a magnifier on the solder pads for one of the voltage regulators. I redid all the voltage regulators then re-installed the ECU. I took it for a road test by driving to check the status of the Baja.......no resets even while driving down some rough pavement. Time will tell. I will be driving the Miata for several days since the Baja need all new bearings and rings. Hopefully it is just that and some more gaskets.
THANKS to ALL of you that have assisted me. This really is a great group! Eric On Tue, Jul 5, 2011 at 12:51 PM, Bill Cardell <[email protected]> wrote: > ** > How many miles are on this car, Eric?
