Re: [Amel Yacht Owners] Exhaust water temperature sensor 7MDKAL
Bill & Judy Rouse <yahoogroups@...>
Fernando, I don't understand, or maybe I am confused or wrong...or, all of the above. I believe that the exhaust elbow temperature sensor has a normally closed switch that opens at about 90c. If one of the terminals was broken off, your Onan should have shutdown after it started. I am unable to test my memory and belief, but anyone with a multitester, can check me on this by disconnecting the wires and checking continuity across the terminals on the sensor. Also they could start the Onan and disconnect a wire to see if it shuts down. Funny coincidence, when I was in Marmaris I had a watermaker tech in the engine room who broke one of those terminals. I did not notice it until weeks later because he screwed the two wires to the remaining terminal. The Onan ran fine because what he did simulated a closed switch. If I would have had an overheat situation, I could have ruined the Onan because I had no working sensor. I learned several lessons on that one.
