P-Mag Operating Temperatures

[sahrens]

Not really much of an installation, but is a quick photo

Has anyone had an issue with a quick turn and not having one of their Pmags firing after engine start on a warm day?

It seems once they have cooled for 1/2 hour or 40 minutes they are fine but if I start within 10 or 15 min after shutdown, only the left Pmag is firing.

Thanks

That has been a problem with some Lightspeed units too. And they were installed behind the firewall.

Nope, hot days here in Alabama they fire right up. Houston, we have a problem! (I wouldn't fly until you get it sorted)

I open up the fuel door on hot days to let the gremlins out, maybe that helps

Never a problem, 800+ hours on a dual pMag install flown on very cold and very hot days.

Recommend giving Brad a call as this is not normal.

I think that only one of them stops firing is a good indication of that one is having issues.

Looked again when it didn?t fire and sure enough getting a flashing yellow light. Pulled the Mag yesterday to send in.

Thanks for the responses guys.

The OP asked if anyone has measured Pmag temps WITHOUT blast tubes. Anyone have that data?

Thanks,
