View Full Version : 2001 mariner tachometer not working

Anyone know where i could get a wiring diagram for my 2001 mariner? I need to troubleshoot the tachometer circuit. im wondering what color is the tach wire from the harness so i can troubleshoot the circuit. It seems to power up when the key is turned and zeros out but doesn't read when running. tried swapping with a known good gauge...no help. Any ideas?
