Hi new to the Joyner trooper family just purchased a 2008 trooper, however the speedometer , coolant temp and voltmeter are not working I was hoping it was a continuity or ground issue but the copper is testing good, it appears the voltmeter is bad as my fluke works off the plug-in behind the gauge, tested the water temp sensor have 5 volts arriving, and approximately 3000 ohms on sensor cold no idea what I should get. As far as the speedometer have no idea how to test again copper seems to have good continuity. Any help would be greatly appreciated. Thanks Dwight
