Today i wanted to go flying. So i did the preflight, had my test plan ready and pushed the plane out. During the preflight i moved the exhaust pipes and the right pair felt a little different. Humm, that is a little weird.
I started the plane and all appered to be working well. When i did the mag checks i knew something was wrong immediately. After troubleshooting i noticed that the number 3 cylinder egt was dropping as soon as i killed the good mag. Pretty easy to see with the engine monitor.
So i taxied back and started to remove the cowl. As soon as the cowl was off, the problem was easily spotted, one of the PMAG wires (#3, imagine that) came off the back of the PMAG. I put the wire back in but the standard click when correctly set on the PMAG did not happen. I found an unused new wire and gave it a try. Click!! So i checked some of the other wires and 3 more were extremely easy to remove. No click. I took some needle nose pliers and crimped the metal portion of the wire. Now they all click and feel secure.
I am not sure what happen. The plane now has 15 hours on it. I know that when i made the wires, they clicked nicely when installed. I will keep an eye on them.
As i was checking around before putting the cowl back on, i found a broken adel clamp. The one that held the right exhaust pair to the engine mount. Well that makes sense.
Got everything back together and went flying. Had a great flight. Has anyone had a similar issue with the wire coming off the back of the PMAG? My guess is mine came off during last flight because the previous mag check passed on the ground.
