rotorman Posted October 5, 2018 Report Share Posted October 5, 2018 My airplane failed the mag check. One wire is bad. I removed the mag for inspection. The impulse coupling was not too far from failing. Researching the new parts took quite awhile. Here is a list in case anyone has to go through this. The airplane is an 1980 M20J with an IO360A3B6D engine. D3000 dual mag 10-682555-11. Please verify all part numbers before ordering. Mag harness with cap new from QAA. M2916, $620. Capacitors from QAA. KA10-400574, $110, two required Impulse coupling. 10-785124-110. Source and price unknown. Will post if I find one.

KSMooniac Posted October 5, 2018 Report Share Posted October 5, 2018 You should talk with Aaron are Select Aircraft in Lancaster, TX for parts and service for this mag. Don't use QAA... there isn't a lot of quality there.Sent from my LG-US996 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

N201MKTurbo Posted October 5, 2018 Report Share Posted October 5, 2018 I got my current harness from KRN. it cost $240. It was a surplus Cessna part. Super high quality. $620 sounds way high. Quote Link to comment Share on other sites More sharing options...
