But how or what do I need to put into my new clock for it to calibrate the reading?

Right, the wires already there from the old clock so that's OK, I just need to calibrate it to read correctly the rpm of the engine...

I remember years ago using a timing lightning my college days back in 2006/7 ish, never used one since lol. Can't even remember what's what.... something else I'll have to buy then I suppose 🤔

 

And I always thought they were for dizzy cap timing?

 

Infact the wire feed is that red one on the w post that feeds the clock  to give the rpm

I was wrong about the poles on the rotor, it is one field coil but the iron is shaped to give 6 poles so the W terminal will see 3 cycles per revolution, . My guess is 3 if it senses ac with possibly just one diode. none of my working alternators have a w terminal.
