My Tach needle does not drop below 5500 rpms when I turn the boat off. It does not have a calibration adjustment that I can find and it is a turned to 6P setting. The wiring harness has grey, black, and purple wires going to the tach.
I also have a like new Yamaha Tach that has a 6P setting, but the wires going to it are green, black, and yellow. Is there any reason this tach will not work with my 1996 60HP Evinrude(Red Plug)? If it will work can anyone tell me which wires are which? I assume that the black is a ground, but I am not sure whch one would be pulse and which one is switched power.
Thanks
