No flow reading from water injection!

It appeared you have done all the right tests so far.

Two more tests for you.

1. remove the flow body from the FAV, blow into the one end, do you hear a whirling sound?

2. If you do, chip on the sensor cable and tell me if you see and bars on the gauge as you blow.

1. No sound = the turbine wheel is jammed.
2. No bar display = the sensor cable is faulty

Hi Richard,

I will do the turbine test, but when I reassembled the turbine after inspection, I could hear a small ''clac...clac...clac'' when the FAV assembly was shaken...meaning that the trubine was not jammed but loose to move a little

Is there an easy way effectively test the flow sensor head (clip) with a magnet (I read somewhere that false flow reading could come from electromagnetic disturbance near the FAV assembly...I then guess that this could be used to test the flow sensor head)!?

Is there a way to test the sensor cable with a multimeter (example : by checking the Ohm reading)?

If the cable is faulty, where do you think the problem is most likely to be (connector, sensor head...)?

Thanks

Eric

You need a cyclic change of magnetic polarity. Your best bet is using the turbine body. Just keeps blowing with the sensor cable clipped on.
