Re: 68 Temp Gauge Problem?
According to the replacement sender specs at the parts store, at 100 degrees the resistance should be 390 ohms. At 260 degrees, 102 ohms.
It sounds like the dark green wire going from the gauge to the sender is shorted somewhere to ground. Normally, if the wire at the sender is disconnected, the needle will peg to the cold side. When grounded, it will peg to the hot side, like yours is doing. See what yours does when disconnecting the wire.
Edit: BTW, .857 K ohms is 857 ohms. Sounds like at room temperature that might be what the sender might read.
