How Do You Test A Temp Sender

[Wildbill]

hi how can I test the temperature sender for coolant temp

It's probably just a thermistor, connect a meter set to ohms across the terminals adjust meter settings until you get a reading, then heat the end of sender the reading should change. A very rough test that will only tell you that it is basically working.

If you think its faulty Bill....just replace it.

Cant be more than 5 or 6 quid.

I see 98% of your present and future electrical problems right there in the dash wireing pic Bill
It's called a Blue Scotch Lock

wat would you recomend solderd joint ?

 

[Geo]

If you have the tools absolutely, failing that just twist em together and tape em up...... now that is bad practice.....but still far more reliable than a scotch lock
crimp connections, bullet connection, male and female spades, there are quite a few options but never a scotch lock if you want reliable joints
IMO of course
