I’ve seen them get in via the holes in the outboard wing ribs for the main landing gear springs.  And there is no way you can seal them up.   

I opened up the tail and looked around today.  No signs of entry, forced or otherwise. 
As per [mention=20223]FlyingDude[/mention], I'm guessing up the nose gear and into the belly by way of some magical acrobatics.

Check the schematics in the service manual. The p-leads should be the same and they should be shielded wire to reduce radiated RF which can get in the radios. I wonder if someone added some sort of filter because or radio noise? The capacitor in the mag should be sufficient. If yours isn't shielded, I would replace the p-lead with a proper one. Bogart is one source. 

Do you have SOS ignition? 
 
is it a 12 or 24V system?

Looking at the starter switch, it looks like one of the magneto (right?) has a thicker wire than the other 20-22 gauge wires, why?

The magneto wires go to a small cylinder mounted to the firewall, maybe a capacitor?

The starter relay has 2 wires connected to what I call the control terminal, 1 wire would be the starter switch, and the other?

Is there a schematic of this circuitry?

Modern avionics all have voltage regulators that’s why they can handle 12 or 24 volt systems. As long as the current is steady it shouldn’t be an issue.

My AV20S reads lower, but not that much.

Wow, I had G3X and 3 servo GFC500 installed for $30K, and that includes new panels.
I think the smaller the job, the more the “overhead” costs add up.

He’s renting but the renter won’t let him get his transition training in said rented plane.

If you get a certified EM, you can lose the factory instruments and will have plenty of room.

Find yourself a sports car (corvette, Porsche, etc) and sit in it. If you don’t like the seating position, you won’t like a Mooney.

I live 200 yards from ocean and get surface salt layer on my car, but the airport is about 5 miles inland and it doesn’t seem to get any in normal weather conditions. Salt attracts water so it’s heavy and will sink (dew) which is why you get the surface salt layer. Now if it was tied down during tropical storms that could be a different story.
Normally airports insist that all tied down planes be either hangared or flown elsewhere.

When was the last time it was treated with corrosion protection?

Interesting that the link no longer works.  Is that because they only keep a limited number of days back or is it because the NTSB is investigating it?

Do you know the size you got?

I got these auto shades, they have suction cups but I don’t need them, just squeeze them into the window frame.

Even if e-LORAN came out next year, GPS Approaches are not going away for a LONG time.
 

Every single time you fly? Dang. 

Would be nice to have some removable covers. I don't know if I'll break out the tape roll every time I fly. 

I just feel better closing the vents and eye balls when I park the airplane.  Probably more emotional than practical.  Was surprised to find these ports open.  

That would make sense.  Forced cooling for the avionics but I don't see a place for connections on the other end.  Perhaps the open end was just secured in place behind the radios?  I'm thinking about capping those ports.  I have an avionics fan now.  

They are suppose to have hoses going to the back of the avionics rack(s).

I have a plastic storage box, and I keep it at home, also have digital copies of the maintenance logs.

Yes, but this was before Covid:
Zephyr did the engine overhaul, and I had Palm Beach Propeller overhaul the prop. I had a cracked case that couldn’t be repaired and replaced it with new case that added around +$4k to the cost.
I replaced the alternator (was oversized and not a normal Mooney alternator) with new. The starter was only year or so old, so I didn’t do anything to it.
I replaced all the control cables with new.
Stripped and repainted the engine mount frame.
Disassembled the baffling and replaced the silicone, had a broken piece replaced with new fabricated one, replaced rusted and broken hot air intake screen with stainless steel.
Painted all the sheet metal to be black.
The oil cooler was replaced by PO, so didn’t do anything but flush it.
Replace some of the hardware on the flaps.

Problem missing something, because of the cracked case it took 4 months , was scheduled to take 2.

I did some of the work and the hours AP charged was double his non written estimate.
I told the AP to mount the engine higher to allow it room to sag. He didn’t do that, now my engine sits a little lower than ideal.

I have a collapsible one like yours.  How is the pipe nipple held in the tube of the tow bar?

One thing I did was put the boost pump switch above the throttle where it is easily reached with one finger. I kept getting distracted and forgetting to turn it off after takeoff and now I keep my hand on the throttle until 1000' and then turn it off before removing my hand.
