Sorry they call them "one wire alternators" but apart from the heavy charge wire from the amp gauge there is a small terminal on the side for the gen light wire.
The power to the +ve on the coil I have taken from 87 on the relay as per the diagram, this is then looped to the distributor as per the Pertronix instructions.
I am thinking it maybe the new relay. If I turn the ignition off surely it should just cut the power. I am going to try a temporary bypass around this new relay and see what happens.
