Had a "glitch" with my G5 today. I wasn't the pilot, it was a friend of mine that is using my plane to finish up his commercial and do his commercial checkride. He was scheduled to do his checkride this morning, started up the plane and everything fired up normally, but when setting altimeter noticed the G5 had shut down. Tried several things to get it started again but it was dead, nothing but a black screen. He ran it over to the avionics shop, they pulled it out and put it on the test stand, dead, until the removed and re-installed the back up battery, then it started up normally. Reinstalled it in the plane and everything worked normal. He missed his checkride, and will have to reschedule to a later date.
Has anyone had an issue like this with there G5?
