Thanks...that's actually a great start (& I had an inkling that was the case), what threw me is the reference to L1 & L2 on this wiring diagram in the manual (which you'll see has a different number of connections on it to my board anyway!)...L1 & L2 look to be both attributed to the DC Motoros & AC mains!




Any idea what the top two connectors at the other end of the board (in my photos) might be for? (I'm guessing possibly a chuck guard switch?)
