Burning regulator

I've been struggling with my twelve for a while, it started with the common melted connectors and oil problem with resulted in a smoking original regulator. I've measured the stator and it showed good 110v on all three phases at 4k rpm. I bought a new regulator from eBay ( cheap Chinese one) and hard wired it as showed in one of the stickys. The bike run good for a month until a really hot day and the regulator burned again. Could it have been bad quality on the Chinese regulator? The stator still measured good at 110v (still original) but when I cut the original connectors from the stator there was 4 wires from the stator into the 3 pin connector. The fourth wire is a small wire which was connected to one of the phases is that right? There is another wire from the stator that is connected to the junctionbox.

Is there something else that can keep burning the regulator?

The wire going into the junction/fuse box goes through a diode and trips the headlight relay which then holds its self in the on position. It could have a shorted diode, so may be worth checking.

For Tech Questions Bike Model letters and Country are more useful than saying the year, for UK owners anyway, as registration year is not always the year of manufacturer model.
