Re: Universal 5411 Cooling

Take both the thermostat and the temperature sensor out and put them in the same hot water bath on the boat.
Wire up a wee long earth return to the ship's battery earth from the temperature sensor otherwise it won't give a reading. Make sure ignition circuits are on but do not start the motor.
Put a wee bit of wood in the bottom of the hot water bath so that they don't rest on the bottom of the heating container. They may get far too hot if you do that.
Now heat the water up slowly and note the thermostat behaviour and the output to the temp guage.
I suspect that the guage is still reading zero when the thermostat opens???
Give it a try.
