Wiring Diagram Mercury 75hp

[Natanich]

Hello brothers. I bought a Mercury 75hp engine, year of manufacture, I don't know, like 1984. Help me figure out the purple wire ... when the ignition is turned on, there is no voltage to the tachometer .. in the engine itself, the wire is not connected anywhere. The question is what to connect it to in the engine itself?

The Grey wire coming from the rectifier feeds the tach. Be careful, it is ignition powered, you may get a nasty shock if you touch any bare wire, while the engine is running. The purple wire is the 12v feed for the ignition system

ie the ignition switch. Radio feed , gauges etc.

And yet, to what in the inside of the engine to connect the purple wire?
