Update on my PMAG that was giving the flashing yellow error when hot. I pulled it and it does have unacceptable axial play. That’s why the Hall effect magnet was tripping the power up BIT when hot. It was overhauled in 2025 372hrs ago by Brad’s company. As far as I can tell it had the new bearings, but I can ask Hartzell when they get it to confirm.

Did you have any indication of a problem other than the flashing yellow light? Can’t see that without removing the top cowling.

Yes it failed the power up BIT. When this happens it acts as a dead mag. If you are pulling tach input from that mag your tach will show 0 too. Once you pull the cowl while it has this condition you will see the flashing yellow.

I spoke with QAA and they are out parts until the end of March

I sent my units into QAA in mid January. Just got them back on March 4th. Tyler at QAA (he does the actual work on them) told me that
parts are the issue. I called Emagair and spoke to Allen. It seems all this parts issue is due to shifting production away from the
original Emagair facility. I sent mine in with 530 hours on them. I've had them running since 2014 and they have done
really well. Over the years I sent them back to Brad for firmware updates and then new circuit boards back in 2019.
Knock on wood, they have done a great job. Folks who have regular magnetos comment on how smooth my engine seems to be.

While the overhaul is expensive, it's essentially 2 bucks an hour if you send them in every 500 hours.

I hope Hartzell improves upon the design and sorry to hear that some folks are having issues. By the way this is a great thread! Always
learning.

If it’s a bearing issue QAA can turn them around in under a week. That’s what happened with mine as of this week. The boards are the long lead item if you need one of those.

Welp at 1,250 hours I finally got bit by the dead mag gremlin. Can confirm the symptoms mentioned here of the heartbreaking Death light, (the amber flashing). coincidentally my Tach reading was on this mag, can confirm the zero rpm readout. I was stranded twice. Ive learned you can cheat and likely get lucky by working the prop by hand....i discovered if you wiggle the prob backwards a little.... you can fake out the sensor enough to essentially get it out "Shut Off" mode. FYI, if you can fire up and both mags run, they won't shut off during flight, however Do Not do the Mag check at run up cause you could end up right were you were before. They only shut off when on the ground and self diagnose upon initial power up. Hence you can fake this to get going. You know, so i can work on this in my AC'd hangar! Anyways, Sending it in for overhaul. Ill report back on time and details of the process-that is starting today. This is a good thread topic, descent comments posted on this one. Mostly helpful. Call into tech support at Hartzell has been great too btw! Be nice to those guys, they have taken on a bit of a mess (to put it kindly) from the transition. Hartzell is fixing alot of caveman stuff in the background guys, that was not being done in the before era. Give them a chance.

I have given them a chance. For an $899 overhaul on my $1,200 EMag, expectations are high. Time will tell if the new bearing holds up.
