[DeTomaso] Vedr: What Water Temp sender do I need? (Was water temp

[gudmund frøland]

I just bought a new sender that worked perfect: On the box it says Motorcraft for 70 Mustang 250, 428,429 W/T
number F 1sz-10884-A

   The TS6153 has a resistance range of 15.2-19 ohms

   The TS6628 has a resistance range of 22.7-25.5 ohms

   A big difference when it comes to indicating on a gauge.  That's why

   your gauge is pegging.  Try the TS6628, you should see a much closer

   reading.  Or, as an alternative put a 7 ohm resistor in series; the

   proper sending unit is the better choice.

   ------------------------------------------

   An alternative to using a 7 ohm resistor with the TS6153 is to use a 10
   ohm potentiometer. That way, you can calibrate the gauge to the sending
   unit. Unfortunately, this requires some fairly accurate temperature
   sensing device to calibrate the gauge against. Once you have the gauge
   reading accurately, by adjusting the pot, remove it (the pot) and
   measure the resistance that was needed to get an accurate reading.
   Then, buy the appropriate resistor, or resistors, and install them
   permanently.
