Hi guys
I am having brain failure.
I just want to make sure I have the Fuel sender hook up correct. I have not cut the wires yet. I don't have the install drawing for the sender (EIS4000-lyc)
The way I see it is that I earth one of the the two wire posts and then attatch the second to Aux 2 (3/4/5/6). This is derived that I am thinking that the sender is just a variable restisor and I adjust the Aux input to calibrate the PX.
That is where I get confused - The Aux inputs are max 4.5 Volts which suggests to me that a positive and not an earth is required. I have spare positive outputs from the EIS as I do not have a fuel flow meter function being used.
I can always hook up an ohm meter to check the gauge - and get 6 psi air to cause a change. But that can cause gauge failure due to rapid changes and spikes.
I tried emailing GRT but no answer as of yet.
I am sure this is not as hard as I am thinking.
