Hi Folks, I installed these reed switches today & have encountered my first significant problem of the build. When testing the switches as instructed in step 5 on page 31B-10, there was no continuity ( the reed switch did not close) when the fuselage pin stopper was snapped into the fuselage pin latch. The switches did not close at any time on either side of the aircraft when the stopper was moved about or removed or inserted slowly. I checked the switches with a magnet external to the system & they work (close) OK. So as suggested I removed 1/32 from the WD1217 tube. No Change. I removed a little more, totalling 3/32, & now the switches close as the stopper pin is inserted slowly, but open again as the stopper pin becomes fully engaged (up) in the hole in the latch. It feels as if the reed switches are too low, but they are definitely held in the cushion clamps as in the drawing. I think there was a thread about this problem a long time ago, but I cannot find it; any advice or help from you builders who have gone before would be greatly appreciated, I am out of ideas myself.... Cheers & thanks, DEAN....
