Update

Unfortunatly my electic ute (pickup) has had some problems. The VFD is tripping with an earth leakage fault. The problem has been intermitent and usually restarts, but this time it let me down and I needed a tow home. I have been testing a few thigns, and short if getting a new motor there is not much I can do. The good news is a new motor is only about $400. This will also give me the oportunity to rewind the old motor for higher top speed. Something along the lines of this post.
