Pretty cool. Any video from inside?

So my alternator is Kelly Aerospace ALX 8521R. Which rectifier I should get? Thanks

Thank you all. I will work on it today.

So what needs to be done to fix it ? Thanks

My low voltage is confirmed by the engine monitor that shows voltage drop. So it is probably real not just a false reading.

Thank you very much.

That's what I have noticed. Unusually whine sound in my headset. Thanks.

Based what I found on the forum I will check recommended items tomorrow. Alternator, regulator, lose wiring, belt, battery, etc. My approach RPMs on short final are around or less then 2200. Don't know if higher RPM shut off the warning. Concord battery that looked and charged good so far. Don't know the age of the battery. Have to read the logs. Unknown voltage regulator. I will look for it tomorrow. Thanks Anthony.

I noticed today on the approach my VOLTAGE light was flashing. The voltmeter read 13.1 Volts. It usually reads 13.7V. I shot off all lights, transponder and radio and it stopped flashing and voltmeter showed normal voltage. My plane is 1977 M20J. Once on the ground I turned on all lights, radio, pitot heat and fuel pump. The voltage dropped again around or below 13volts and red light was flashing again. After shut off the battery voltage was 12.6 Volts. I will search the forum for low voltage topics but if can pint me to the right direction I would appreciate it. I can think about two possible issues : 1. Alternator belt is slipping under higher current draw conditions 2. Something is going on with the voltage regulator ( or whatever it is) Thanks

Sweet. I fly over JFK very often and never thought I could land there. Did you call tower or anybody prior? Any other concerns besides navigation and ATC com? Thanks.

First to reply. Bam.

I am just curious as I do my regular oil analysis and filter inspection. 1. What engine you have in your J? 2. How many hours SN or SMO 3. Do you find anything in your filter ever? Small shiny flakes? 4. What is your iron and other metals level from the analysis? Thanks.

Please stick around on this forum. We need you.

Sad.

Happy to help.

Air mods. No question.

Awesome. Congrats. It is pretty big deal.

When you are practicing ILS approach and another plane is taking off in opposite direction he didn't hear and see you because your frequency is 127.2 instead of 122.7.

Impressive. Very nice. I get nervous when my fuel monitor indicates less than 30 gal and I am in the pattern.

Where do we park ?

Yes, I took the pic on the way back from avionics shop. We didn't set it properly as the storm was coming so I took off. Next day I flew for 3 hours and made adjustments. It is very easy to make any adjustments. Tilt, roll ( +, - 1 degree steps) , IAS, altitude, speed limitations, etc.

Yes, my TC stopped working so I just replace it with this.
