On my alternator, not a true one wire alternator, but a 2.5 wire
alternator, it would not start charging unless it got over 1,500 or more.
All it needed was a blip on start up. But it still needed it.
I said 2.5 because there is the light wire and the power wire, but the
power wire is jumped over to the third wire. So, while the alternator has
three attachments, only 2 wires actually go to it.
It has been a while since I did this. But I seem to recall that the light
wire goes to the post marked "S". But no one should rely on that - I'm
happy to confirm though.
