Testing water temp sending unit or gauge JD 425 | Green ...

07/08/2020· If you ground the wire that goes from the temperature sensor to the temperature gauge, the gauge should read "hot". Not sure about your machine, but on mine that wire is yellow/blue. If grounding that wire gives you a "hot" reading, then the sensor is bad. If grounding that wire does not give you a "hot" reading, then test the gauge.

Engine Temp Monitoring And Overheating ... - Marine How To

It tells me the Atlantic Ocean under the boat is 68 degrees and that means the temp my raw water pump sees is also 68 degrees. Take this reading and save it to a Word doc. or just write it in a notebook. This is not a critical reading but nice to know each time you check. If the water temp was 32f then I would not expect the same temps elsewhere on the engine but if it’s within 5-8 degrees ...

Testing water temp sensor | Sea-Doo Forum

27/07/2017· Based on this "Monitor Beeper" test straight from the manual, I conclude the temp sensor is a on/off switch. So yes you could check it for continuity cold, then check it for continuity hot. I suspect you would need to put it in a pot of boiling water (no different than testing thermostats) with some jumpers to measure continuity.
