I ended up replacing the alternator after chasing down a lot of less expensive options. No trouble since then.

In his article in the May Mapa Log, Richard Simile says, "Never CROSS CONTROL an Mooney during a normal landing or anytime really." The POH for my 1988 "J", says to slip into the wind keeping the plane aligned with the runway. These two statements seem contradictory. What do you all think?

Who and how can I get info on M20J 2900 lb. gross weight increase?

While flying a coupled approach with new GFC 500, noticed an engine vibration when the power was pulled back during approach. Checked mags and mixture, no change in vibration. Increase or decrease throttle will make it smooth out. Same thing on a second approach. Ground checked everything I could, can't find anything wrong. On take off and cruise, smooth as always. The vacuum pump is still in the engine, even though none of the instruments are using vacuum. Any ideas?

I have an '88 J model/205. The DG function of the HSI is not working. The DG compass card stays stationary when the heading changes. The little striped flags are visible. Any hints on how to diagnose without going to the avionics shop?

Can anyone recommend a source for a 28V voltage regulator for a 1988 J/205?

Hi, Please add me to the map. I don't know if I have the link. Jack46

jlunseth, Thanks, that's high praise.

About half way from KBTL to KOWB to attend a MAPA PPP session, the alternator field circuit breaker popped. I shut the field switch off, and reset the breaker, turned the field switch back on. In about 5-10 minutes the breaker popped again. I repeated the reset process. I told myself if it happened a third time, I was RTBing to KBTL. In about 5-10 minutes, it popped a third time so I did a 180. On the roughly 45 minute flight back, the breaker never popped again. So, now I'm wondering if I made the right decision. Is this an issue that is just annoying or is it a safety of flight issue? How can I differentiate? What happens if I just keep re-setting the breaker? Is this caused by the alternator, voltage regulator, weak circuit breaker, something else? Has anyone else experienced this? Jack

I had the exact same problem in my 1988 J. The relay part number is the same. I found one for $600 with no guarantee it would work. The local Mooney service center advised making sure none of the circuit breaker terminals were coming into contact with the buss or the relay. In my case, we found corrosion on the relay terminals. The relay bench tested fine. Since cleaning up the terminals and making sure there were no other contacts, it has been fine. Fingers crossed because the kit from Mooney to fix this costs $1200 to $1400, not including installation. JB

I'm looking for someone who might be interested in riding shotgun from MI to Yuma for the Caravan Formation clinic February 1-4. If so, send me a message

SOLD

The a/c serial number is 24-3068. The shop said the part no. installed is MB4413 manufactured by Potter Brumfield

The failure mode is, it sticks on. Meaning, when I put the avionics master in the "off" position, everything stays on and I have to shut them down individually. That means, after start up, they have to be all turned on individually.
