hi Jack,

I did check continuity of the wiring from the sender to the gauge/cluster by doing this:

- measure the voltage of the wire and ground I got 10.5 V

- shorting the wire to ground and the gauge went up to max with the red light blinking

- measure the resistance of the sender in Ohm, it show the resistance varies when I apply heat to the sender

so (according to me),

- the sender is OK (I have 2, measured both and they show same)

- there's signal from the sender to the gauge, the gauge reacts when I ground the wire, but some how the gauge did react to the signal from the sender (which is good)

I am at lost....

thanks
