My tach is not working.
I've checked continuity between the (grey) wire at the tach and the appropriate pin on the ECU's wiring harnesss off of the ECU itself - it's there.
I then checked the signal on the wire at the tach with an osciloscope, nothing's there. Just some minor engine noise. I can't get to check the lead itself off of the ECU becuase I would have to unplug it to access the output signal.
Any ideas?
Thanks, Zig
