[DeTomaso] Speedometer

[jderyke at aol.com]

Probably the wrong speedo ratio- as Julian said, there are two, with two different cable attachments so four choices. Two ways to fix: one is to trade for the other ratio and the other is to go to a speedo calibration shop for an external ratio box that inserts into the cable drive on either end. They have several different available. The trip reset cable drives a separate gear drive inside the speedo. A shop can fix that too.

  Steve,

  No the odometer and trip odometer are both off approximately the
  percentage the speed indication is off. Additional information but
  perhaps not pertinent the trip odometer has not been able to be reset
  for some time.

  Thanks,

  Jim

  Curious - if you drive a mile, does the odometer show a mile?

  All,
  My speedometer reads around 42 when the car s going 55. The tires are
  the
  proper diameter and the Transaxle is the original. It had been
  refurbished
  as needed during the restoration but no indication the speedo drive had
  been
  touched.
  The needle is dead steady (it did need a cable replacement post
  restoration).
  So now I need to confirm it has the correct speedo drive before I go
  further. Is there a method to detect externally if the drive is US or
  European? Most particularly is there a way to tie the drive to the ZF
  by
  some identifier? Or do I need to remove the drive and count teeth or
  something like that?
  If the drive seems correct, The last component is the Speedometer. Can
  these
  Speedometers be re-calibrated?
  Thanks,
