Apologies for the long post. Went to look at a mates JD earlier. Test report says 5 switches aren't working. None of them are in the same column or row. Go into switch test and none register at all although there is power showing. Not one coil is working either inc the flippers. Forgot to check whether there was power there as was in a rush but when I grounded drive transistor tabs quite a few made the planet motor and crane move, other tabs did nothing. Where the hell do i start on this. Ken
