You might use an o-scope to verify clean and consistent square wave.Tach is a pulse counter and integrator. It will need power (+12v and GND) and a pulse. Verify pulse is making it there at the same amplitude as at the flywheel.

Rewired my engine, now tach fails to work. Tried new tach no help. Pickup off flywheel shows an ac voltage that increases with rpm. Tacoma desiel had me check cleanliness of pickup. No dirt. At a loss. I need help. Doug Mountjoy Sv Rebecca Leah C&C LF39253-208-1412Port Orchard YC wa._______________________________________________
