ECL-1 Shutdown and BOSS Pinouts.

[MrBobcat753]

Looking to diagnose fault on 753 with BOSS Unit. Do not have diagnostic tool. Have swapped out ECL Sensor and checked continuity. Anyone have BOSS diagram to have to hand with the correct Output Voltage from the BOSS to the Coolant Level Sensor? Currently 0.15V which seems low. I have seen service manual with values for other engine sensors but the Coolant one isn't given.

Also if you have resistance values for the sensor that might be helpful, thanks.

Forget that its probably capacitative.

The ECL sensor relies on a good ground connection.
I looked through all my Service Manuals and did not find any information on the operation or testing of the ECL sensor.

Engine coolant sensor is a variable resistor that changes its resistance depending on the temperature. Tonight I can check at what degrees how much ohm should be.

I apologize, I have confused this sensor with the temperature sensor
