Hi all,

I just replaced the odometer/speedometer driver (circuit board) to correct a blown driver problem. (Yes, I pulled the plug-the-tach-wire-into-the-wrong-plug stunt.) I got another one from a junk yard with the same code -- K9800. The problem is that the speedometer reads higher than it did before, and I think that it was reading a bit high before. I would like to correct this and am looking for information about which resistor(s) should be modified to calibrate the driver.

Anyone have this information? I would rather not do the trial-and-error thing.

Thanks for any help/pointers.

-- Matt
