I have noticed here lately that the gauges (temp, oil, and fuel) are sometimes reading higher than normal. I have seen them sometimes jump to the high side of the gauge then come back down to normal. The usual readings are Temp: 3 marks from "C", Oil: 2-3 marks from "H" while cruising. But lately the temp has been 3 marks from "H" and Oil is almost full scale (right). My first thought is something is wrong with the motor, but I have seen them all come down at the same time at the same rate, which leads me to believe there is something wrong with the gauge cluster. The fuel gauge also jumps about 3 marks when the other 2 are moving.
Can anyone point me in the right direction as to where to start looking?
Thanks for your help!!!
