Title: How can I check the engine Temperature sender
Post by: Eaton_FE on December 13, 2009, 05:18:06 PM
I am not sure if my engine temperature sender unit is working or not, How can I test it to see if it is. If I short out the wire on it to the body the light works.
The milion dollar question is how do I know if it will come on when the engine it hot.  ???

A rough way of checking it out is to take it out and hang it in a tin of boiling water and using a multimeter or continuity tester across the terminal and body of the switch--you should have a circuit.

I have used this method too, works very well. The resistance should change as the water cools.

Sounds like it is a good idea, I will give it a go.
