Did the prop rod pull apart?

Sounds like a wiring issue. Could be a regulator, but you just replaced it. There is little an alternator can do to cause an overvoltage.

It sure sounds like a cable problem. Did you push and pull on the cable housing where it is secured at the governor?

I wouldn’t use aluminum tape. It seems to come loose eventually. I would use fireproof fiberglass aircraft tape. I believe it will last longer. https://aerotape.com/products/polyken-290fr-cargo-tape

How about some pictures of what you have.

I spent a few years in my youth doing land mobile radio work. I serviced some sites that had FAA equipment in the same buildings and would sometimes run into the FAA techs when they were working in their buildings and would get to see their stuff. This was always on top of some mountain you had to go 4-wheeling to get to. Their equipment was almost always in sad shape. Like nobody cared about it. The FAA techs had a bad reputation in the industry. A couple of times myself and others would have interference issues caused by the FAA radios. Normally, when that happens, the two parties would work together to resolve the situation. The FAA techs were hard to get ahold of and if you could get ahold of them, they would just tell you to F-off and it wasn’t their problem. Of course we could see on our monitors that it was absolutely their problem. We reported them to the FCC, but they said they couldn’t tell the FAA what to do! This was all 40 years ago. I have no idea what the current situation is.

That is a tiny fraction of what’s in the Stratoflex catalog.

If you glue the double sided tape down with some better adhesive, it will eventually fail at the other side of the tape. The only way I’ve ever found to make them reliable is to scrape off the double sided tape, clean the surface and glue them down with RTV. You have to tape them in place overnight before you use them. It isn’t very convenient.

I just cut them out with a scroll saw.

What does the IPC call for?

Call a hose shop. If you look in the Stratoflex catalog, it shows all the different hose/fitting combinations.

I’ve seen some late models with way more avionics installed on that shelf than I’ve ever seen in a C model.

The connectors were made by Molex. They were discontinued in about 2015. People went crazy, so they started making the pins again. I don’t think they are currently making the housings. If you need a housing, it will be used or old stock. The situation may have changed, so check it out for yourself.

I would never use the adhesive mounts in an airplane. They will always fall off, at least around here. I used to service a Rockwell Commander and all the landing gear wiring was held on with adhesive wire anchors. They kept falling off. When they fell off, all the wires would get ripped off the switches. Then you don’t get a green light. I have been working with automation equipment for decades. Wherever they are used, they eventually fall off.

They sure look purpose made for this application.

I spent way too much time looking for the clips Mooney uses. It looks like a Tinnerman product. I found the complete catalog and looked through the whole thing and couldn’t find it. The search words are speed clip and speed nut. It is a combination of the two. There are other manufacturers of speed nuts and speed clips. I will try to find their catalogs. There may be a mil spec that covers these and I may be able to find them there. I guess someone could contact Mooney and ask for the part number.

When I bought my old Cessna I acquired a gallon of pure TCP. It was added to the fuel to keep the plugs from fouling. The O-300 in that plane was designed for 80 octane fuel. 100LL fouls the plugs and the TCP was supposed to help. I worked on fueling systems for jet drones. The engines did not have an oil system and they were lubricated with fuel. TCP as added to the JP-10 to lube the engine. https://www.prattwhitney.com/en/newsroom/news/2017/08/03/small-but-powerful-the-tj-150

I have mixed feelings about lacing cord vs Ty-Raps. I used to work for the phone company and laced miles of wire. It makes for a very neat wire bundle. It is certainly easier to pull a bundle back that is laced vs Ty-Rapped. I have never cut my hand on lacing cord. It takes longer to lace wires than putting on a Ty-Rap. It is difficult to lace wires in tight places. I do both. Ty-Wraps were developed for Boeing to secure aircraft wire bundles. https://global.abb/group/en/technology/did-you-know/ty-rap--cable-ties#:~:text=The Ty-Rap™ cable,cable ties have been produced. The idea of the cable tie came to Logan while touring a Boeing aircraft manufacturing facility in 1956. Aircraft wiring was a cumbersome and detailed undertaking, involving thousands of feet of wire organized on sheets of 50-foot-long plywood and held in place with knotted, wax-coated, braided nylon cord. Each knot had to be pulled tight by wrapping the cord around one's finger which sometimes cut the operator's fingers until they developed thick calluses. Logan was convinced there had to be an easier, more forgiving, way to accomplish this critical task. For the next couple of years, Logan experimented with various tools and materials. On June 24, 1958, a patent for the Ty-Rap cable tie was submitted.[10]

I never noticed and I didn’t have a recording monitor. The power will drop a little and it may take a bit for the prop to catch up. Just like when you do a mag test and the RPMs drop a bit on one mag. The same thing will happen in cruise.

Your adjustments may just be a coincidence. It may have came back on line if you did nothing. I have had mags do this where it just goes offline for a few seconds and comes back. It is usually because the point gap has gone to nothing. This may be caused by a bad condenser.

If all your EGTs went up, a mag probably quit working. If it does it again, do a mag check.

Yeah, I still have my day job.

I just spent 1/2 hour looking for them in the IPC. I can’t find them.
