I’m based out of SFB and own a 1970 M20C. I highly recommend AirWerks LLC. They are located at SFB, and the mechanic, who is also the owner, owns a Mooney M20C as well. Sent from my iPhone using Tapatalk

We seen this before, this is due to improper wiring. Some installers are very very sloppy when it comes to crimping pins. Have a knowledgeable shop or installer verify the wiring at the GMC 500 connector and at the switch itself. Sent from my iPhone using Tapatalk

Garmin has only granted permission to dealers to use their STC. You would need to find a dealer who is comfortable with your work to sell you the brackets, and give you access to their manuals. Unfortunately, not many dealers are willing to work with owners when it comes to Garmin stuff. The GFC500 is worth every penny. I have one in my C model and love it.

I would recommend leveling the airplane and completing the calibration that way. You can’t account for panel tilt if you input the degrees from rivet line. Below is my set up, this is what calibration looks like with aircraft level vs what rivet line showed with aircraft off jacks, and how it looks flying. Hope this helps.

That looks like your Lo/Hi vacuum sensor. That line should be connected to your vacuum system, otherwise you’ll get a low vacuum light on. Sent from my iPhone using Tapatalk

Your best option is to install it on the Avionics shelf in the back. Sent from my iPhone using Tapatalk

Hello, hope this helps. I had the same issue and it turned out to be a bad diode. Sent from my iPhone using Tapatalk
