Hank i just did a little experiment. It appears that mine is not kosher in the continuity stakes. What it looks like it is intermittent. So checked my mill and that is, the 2.2kw on the router is also. It could be a question of the grease breaking that connection? So i fired the 300w spindle up and let it run for 10 mins to get the grease going, guess what....connection all the way.
