eng622 Posted April 9, 2023 Report Share Posted April 9, 2023 Checked the water temp sender and it has resistance hot and cold. Connected a 39 ohm resistor from the sender wire to ground and the gauge still no reading. So assume it is the wiring or the gauge. Anyone have the wiring diagram wire to sender is blue/green.

RobH Posted April 9, 2023 Report Share Posted April 9, 2023 Basically that green/blue wire goes all the way to the temperature gauge though there may be joints in between (?). The gauge itself has three connections, power (white) , earth and sender. Quote Link to post Share on other sites
