I am on the west coast but up in PNW. The temps here last couple of weeks has made me start to wonder about heating efficiency inside the hangar. I have a Reiff engine + sump pre-heater but when the temps are dipping down to < 10 DF and with the tendency of the hangars to remain cooler than OAT - it begs to be cautious and do what's needed to keep the heat contained with the engine bay.

When I had Voltage Regulator issues, I had mine rebuilt by Consolidated Aircraft Supply in New York - https://www.consolac.com/ Might be worth giving them a quick call to see if they can service it for you and what options they might have. Mine came back like new.

Okay answered my own question: https://www.airplane-covers.com/mac/cowling-covers/#MOONEY Mac's costs roughly $280 Bruce's custom covers also has one for insulated engine cover but they also have prop and spinner cover which is handy: https://aircraftcovers.com/M201 ~$500. Guessing justified by "Insulated Covers Material - A special composite material of solution-dyed polyester, 3M Thinsulate insulation, and soft nylon interior fabric." Scroll down to your specific model.

Got a link to the Mac insulated cover?

Here's the Mooney instructions (scanned using iphone, sorry for the quality): INSTRUCTIONS.pdf EFFECTIVITY.pdf RADIO MASTER.pdf

Here are the pictures as promised, got the old relay installed which will be swapped out for the solenoid. (Instruction PDFs in next post)

Yep, many folks at various service shops on the west coast knew/know him. His signatures are all over the aircraft logbooks. He will be happy to know the bird is well taken care of

Nope, but maybe will look into it. My family is growing so this is definitely something to consider (after of course, more space in general - haha)

> Technically no, I have not. But the previous owner did. Yep - I remember our discussion on the Encore conversion. Mine will be going through that this year or next! > Strange that the N-numbers did not sequence. Or did the go from XM to XN to XO then at sometime back to xM Wondering if anyone who worked at Mooney can chime in on the pattern they used. Could be topic for Mooney Max!

We are pretty darn close though @Aerodon curious if you ever had your bird serviced at Advanced Aircraft in Oregon? I know @Pinecone has, mine goes there now. Maybe another similarity?

I am hoping third time is the charm - been wanting to attend since 2022...2024 it is!

Couldn't have captured it better! Maybe they test the aviation ones for repeated heat cycles and tolerance up to certain temperature ranges. I tried looking at tech specs on the Summit Racing site but couldnt find it on their site. On a race car - if you don't already have a fire restraint system, you can still pull over, unlatch your harness and jump out. Up in the air, we are SOL'ed and can't just crash the plane to "get to a quick exit".

Haha - that's what I get for doing things late night. You are absolutely correct - the terminal numbers match now. Updated the PDF in the post above.

Thanks @Aerodon will have them check it. I am quite certain I have the original relay from a quick peek last week. The other symptom that I commonly observed was that during shutdown, the avionics wouldn't shut off after the first try at flipping the switch, typically took 4-5, maybe more to eventually turn off. I decided to dig in to understand it a bit more, attached you will find the parts list for my 252's Avionics relays schematics with the interesting areas highlighted and connections traced. Schematics M20K-AVRelaySchematics.pdf Update 1/15 - Fixed avionics switch trace to GND bus. Thanks @Aerodon

Interesting. I definitely had times when the avionics stayed on and wouldn't shut off through engine start **cringe**. Agree, the part I received looks like your solenoid. I will send pictures this Friday when I head up to the shop again.

Agree, but its too late. I believe they did do some troubleshooting - my guess is listening to the relay to hear the clicks. At the end of the day, I am thinking of buying the relay as keeping Mooney afloat :-)

I am sure many folks will buy two if not three for backup

Yeah once they are done with the current work and harnesses are back in and connected, will have them troubleshoot before replacement.

@Aerodon Thank you! The detailed pictures and the guide is amazing. Hopefully others will find your post helpful in the future as well! I will send photos of the new relay next week when I drive up there again to check in on status. If it comes to it, they sure will appreciate your pictures. Thank you again.

Sorry if I wasn’t clear - Mooney sent me the (expensive) replacement relay so already have it here. Pictures would be great! Thanks Don

Not quite sure but guessing so. The MSC replaced the switch as a first test, that didn't remedy the issue. They suggested it was the relay so I now have that. The plane is at a different facility, local avionics shop, getting some avionics installed and I wanted them to tackle this as part of the job.

Has anyone replaced their Avionics relay after it fails closed (avionics stay on). For my 252, Mooney provided 940074-503 which replaces the MB4413 original part. See retrofit guide. Plane is in the shop, would appreciate if anyone has pictures of the installation. Tips appreciated as well!

Thanks folks - Would love to take you up on your offer @Bolter and sit on the right side to see whats involved. Then eventually start the training locally if possible. Heading away for a few days currently poses a small problem logistically.

Hello! Signed up on Mooney Caravan but do not see any formation clinics scheduled for the PNW region for 2023. There's a B2OSH event in June but that seems more geared towards preparing for the trip to Oshkosh. Anyone who can provide some guidance on next steps? I do have link to the Learn page at Mooney Caravan and will start on it once I figure out where I can use that knowledge Shawn
