Yes i had found that same image but i'm still not too sure about the meaning
I _think_ this is a point to which you can attach a tachometer and it gets an output current that is proportional to the induced current in the stator windings?
but my rev counter runs off the main engine alternator
so i'm left wondering what else the white wire could be
I guess my main concern is will i damage anything without it connected
My guess is no - i might just notice a light off somewhere??
perhaps i'll just need to try and see
thanks for your advice
All the best
