'83 interstate temp and fuel gauge

Post by robinasq » Mon Jul 16, 2012 6:09 pm

Suddenly the temperature and fuel gauge are increasing ; all the way to the right. My fan comes on, I have plenty of water and oil. The gauges sometimes slowly go back down while riding. I know they gauges share a sensor.

Is the wing really quickly overheating ? Is there an easy way to test the sensor.
Thanks for all your wisdom,

When both gauges suddenly rise or drop,the common denominator is the 7 volt regulator.it can go intermittent.it's located dead center behind the instrument cluster.The original unit has 3 wires on it and is a metal box about 1"x1"x1 1/2".new style replacements can be purchased from this site in the "Store" section.
As far as testing,you have to get to it first.there's 12 volts going in and 7 volts going out to the gauges.

Remember this is only if both gauges go up or down at the same time.
