Temp Alarm Sender for Volvo Penta

[islandrunner70]

Have a diesel Volvo Penta model 2003. When I had it survey the mechanic said the temp alarm sender was the wrong part because the wiring connector for the alarm did not fit the connector on the sender. The are two wires on the engine, one is for a temp alarm and the other is for the temp gauge. My boat doesn't have a a gauge only an alarm.

The tech determined this by shorting each connector to ground, the one that triggered the alarm was the correct connector. In my case the alarm connector did not fit the installed temp sender. He said the original my have been replaced with the incorrect model.

Is this possible? Does anyone have a model number for the correct temp sender. It looks the wider connector is for the guage and the narrow is for the alarm.

Thanks

Islandrunner, before you make up your mind on buying a senser, price one from Volvo. Be seated when you hear it. You might want to consider buying the plugin connector that fits your senser and only useing the wire that goes to the alarm. I think you will find that much less expensive. It is worth looking in to it. You might even take the senser out and go to an auto parts store to get a connector for even less than Volvo, and I doubt that the quality is one bit less.___Good Luck____Grant.

The temp alarm is only a thermal switch. If the connector doesn't fit, just cut it off and crimp on the correct one.
