george, i don't need a fuel gauge, i have a fuel cell. the car is only built for race. that's why I only need the rpm, speed and temperature.

I think he means that the tach wont work if the fuel gauge is not getting a correct signal. Should be easy to eliminate that as a possible problem with 2 resistors.

[choyr]

so it's pin 5, pin 12 and pin 13, just put 2 resistors for the Fuel gauge? is that 126 and 180 ohms?

To Choyr: This is how it must to involve.

thanks george. tomorrow I'll try this. no need to ground the pin 12 right? just connect these resistors.

... pin 12 is ground for fuelsender.

As promised, I have try to change a resistor and now it's OK

I've made a picture of the resistor to change but I can't seem to find it on my hard drive
As soon as I've found it I'll post it.

finally got the time to continue my KE70. i tried connecting again this digital cluster and followed this drawing, simulating the fuel sender, but still the tachometer is not working. is this correct?

[Ivan141]

Pin 11 should be ign-, not pin 10.. according to my data at least.

[choyr]

oops, sorry. the picture is wrong. i'll upload again.



anyway, i cant find an exact 126 ohms. 2 and 5 are connected to ground. this is correct?
