I have no helms manual, i'm trying to find out if there is anyway to check the coolant temp sensor. thanks

 

the fan sensor or the guage?

 

the sensor that reads the coolant temp

 

there is a one wire connector on the bottom of the head that runs the guage. a two wire connector on the t stat housing that runs the fans.

 

there are two - one that tells the ECU what temp(ECT) and the other for teh cluster gauge.

to test the ECT one, it should read about 1000 ohms at 100'F

HTH,

t..

 

Try THIS.

Now that you have the resistance specifications from Chris, if you need to check the calibration, I put them in a pan of water with a thermometer on the stove. gradually heat and compare resistance with your thermometer of choice. I use a refrigeration dial type thermometer.
