Smartcraft question-Engine Temperature

[joesearay2003]

2003 Sundancer 340. Started up my engines. Both engine analog gauges show 159 degrees for port and starboard. Opened up Smartcraft. Showing 159 degrees for both port and starboard HOWEVER graphic is showing engine is overheating and it is blinking "HI" next to the starboard engine temp graphic. Any ideas?

Looks like that temperature switch is bad or the wire is shorted to ground. Actual temperature measurements are done with thermistors and discrete Hi/Lo are switches; two different sensors. The discrete is a single wire switch.
