Temperature Gauge - Sea Ray 180
I have a 1999 Sea Ray 180, and the temperature guage is reading 170 deg when running. I replaced the thermostat and the impeller but no change. I used a temperature gun pointed at the thermostat housing and it read a steady 145 deg while idling on the muffs, the gauge read 170.
My question is this, has anyone added a resistor in series with the gauge to "calibrate" the gauge? If it is a resistance meter then theoretically this should work, it would add some bias to the gauge.
I plan on trying it out with a potentiometer while running, set it so the gauge is reading the same as the gun then shut the engine off and while it cools I will compare the gauge to the gun to see if it is still accurate throughout the whole lower range. If everything works out I plan on replacing potentiometer with the closest stock resistor size.
Has anyone else done this?
Thanks.
