Using a Tachometer with a engine sensor

Hi Dave

All it says on all drawings is Stop magnet for the stop. 
I have 2 wires coming from the sensor to the old Tachometer. Will both wire be connected to the new tachometer? I ask since i know from the fishing boat that there are only one wire going from the alternator to the tachometer there. It's just so i know how to connect all this again:-)

Will go offshore later today, so are a bit on/off here, since i will be working nights out there. But will answer during the evening/night.

Regards
Tommy
Hi Tommy
The wiring for the sensor is normally [ live in - body negative - sensor output ] so two wires.
You should find that you have a wire coming from the ignition switch to the sensor and one from the sensor to the tachometer. The output is normally 5v high / low logic flat pulse. The tachometer counts the changes in state. You will still need to follow the tachometer tuning instructions to set it up.

Hi Dave

If you looks at picture attached, you see both wires goes from sensor to Tachometer, Wire J & K. They goes to G & W on tachometer.
Which wire should i connect to the new tachometer?

For the stop it sounds right.
