Ferrari Mailing List: Re: Water temp gauge troubleshooting

[Mark (misc]

Nope, the sensor doesn’t move.  Thus, could be either.  I also feel it is the sensor- or connection thereto.  Do you guys know if the sensor is a thermistor(reduces resistance) or thermocouple(creates voltage) to sense the heat?

My guess it's the sensor not the gauge 

Does the gauge move at all?

If so that's your answer, it's the sensor

My water temp gauge has not worked for a while, and as long as I have sorted out the other 308 temp issues, I may as well knock that one off also.

 

I need to determine if it is the pickup or the gauge

 

Thus-

 

1)     If I pull and short the temp thermistor(I assume it is a thermistor??) leads what should the gauge do?  Full max or full min?

2)     If I put a resistance(how much??) across the temp gauge leads, what should the gauge do?

 

Other quick tips/tricks to determine which is bad??

 

Thank goodness the wiring doesn’t go through the fuse block…..

Ps – another shout out to Paul Bennett and his 308 wiring diagram jpg – awesomely usefull !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
