So what was it
regulator
No. I'd screwed up. Had two separate diagram illustrations for the power connection to the regulator. The regulator itself isn't marked + and - .
One was supplied from a manual page. One was supplied by a local from the dealership who said he'd printed it from SPOC support. The two sheets contradicted each other. To break the tie I'd asked at the local service department which was correct. Service writer told me he looked at a bike to confirm so I took his word for it. Turned out that was wrong. So I had the positive and negative leads to the regulator crossed.
After having checked everything else I was concerned that might be the problem so asked Scott to double check it on his bike. He confirmed the actual connections and that I had mine backwards. Fortunately must be decent polarity protection within the regulator as making the quick change cutting and reconnection the two wires had it working just fine.
That meant I had the choice of the red or chrome regulator (since this was done after the chrome piece had arrived). I liked the look better with the chrome regulator.
If anyone is ever doing the three phase conversion and needs to know the connection from the stator to the regulator doesn't matter. Any orientation is fine. The connection from the main harness to the regulator consists of two pins. Orientation is front to rear with the regulator installed. The front pin is ground and the rear pin is power.
