    ON an old 1988 Pete 377 we have it is in need of a tach. The one in it is verified "dead" as I swapped a good working one to test, and it worked. Anyway, I checked a few salvage yards in Kansas, and nobody had one. So I called Doonans(Peterbilt dealer) out of Wichita, and they have a new "replacement" tach. Said something about having to be calibrated to truck or something such as that, plus it was over $200! Yikes! Anyway, how does this new tach work, as far as "calibrating", does it have dip switches or something?
    thanks,
    Jim

    It has dip switches on the back. I recently replaced mine with a new one, it was around $200. It will come with a chart telling you how to set the switches based on how many teeth are on the flywheel. Try mid america peterbilt for a price over in o'fallon mo. I think he will ship it to you
