Ferrari Mailing List: Water temp gauge troubleshooting

[Mark (misc]

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…..
