Vane air meter
I'd like to use a vane air meter like those used on the Turbo Coupe as an air flow meter for a project. The problem I encountered was that I can't find a diagram indicating which connector is for what. The meter I have is from an 89 Probe. It has 7 connectors, from left side I gather the first two are just a switch indicating whether the vane is open. The third connects to the board and also the temp sensor. The next two connect to the board. Sixth goes to the sprung sweep arm that is rotated by the vane and sweeps an arc on the board. Seventh connects to the temp sensor. My problem is that I haven't been able to feed a 5v signal on one connector and get a return signal variable with the opening and closing of the vane. Seem to only get full 5v back.
Anyone have any info or experience with these? I'm a little stumped. What I thought could be straight forwards, isn't! DOH
