  1. I bought a 1982 M20J 201 back in April and I took it for my first night flight the other evening. I didn't notice anything unusual until I was in flight for several minutes, at which point the panel lights started changing intensity at a rate of perhaps 2 Hz...bright-dim-bright, a bit random. I then looked at the ammeter and the needle swings pretty wide left and right of zero in time with the panel light fluctuations. I have a JPI EDM-700 and it logs various voltages from 13.6 to 14.5. The problem is also intermittent. Most times it doesn't happen until in flight (I've made
  2. Yesterday I tested the Standby Alternator in my Ovation 2 29-0363 (905 hours TTIS) all according to the published procedure, and it failed. To track down the fault the top cowl was removed, the prop rotated by hand, and we found the alternator was not rotating, so the problem seems to be the shear coupling. Have any other readers experienced the shear coupling failure, and at what TTIS? Was the alternator replaced or overhauled with the shear key replacement? It seems that the alternator is essential for TKS equipped Ovations, but not essential for non TKS. I'm not overly confiden
  3. When reading the electrical schematic, each line is annotated with something like 21WE17B20. I assume this is to help identify the line at the source and destination. Do the numbers have any other significance like wire gauge or voltage or anything? PS. Are the fuses indicated anywhere on the schematic? Not a lot of experience reading these things.
  4. My 78' M20J has had a couple of odd electrical happenings the past couple of flights and want to see if there are any experts or fellow owners who have had the same issues and found the culprit or if these could potentially be all from a similar issue? Issues: - Wobbling Ammeter (going to first try Don Maxwells suggestion of cleaning Master Switch and connections here), but I have noticed that over the last two flights the high/low warning light has come on and instead of a slight wobble it is doing about a 1/4 deflection in the wobble that is pretty big. Unfortunately I just found t
  5. Hi All, I just returned from my first business trip in N252DR, a 1986 252 Rocket. She had been parked for a while before I bought her but Jimmy Garrison & Don Maxwell provided an accurate assessment of her condition. Maxwell finished an extensive annual the last week of August & the flight home from Longview TX to Ocala FL was nearly trouble-free. Last week I made a 1700 mile trip to Columbus OH, Destin FL, then back to Ocala. A few (hopefully easily fixable) bugs appeared and I'd really appreciate a little crowd-sourced troubleshooting advice. Here's what I found: Panel lig
  6. Good Day Mooneyspace folks, I look forward to any insights related to the following issue: Fresh annual, engine run-up to validate a tachometer replacement. Prior to engine shutdown, noticed "high low volts" flashing on annunciator panel (s/n 24-1580, 14v electrical system). Problem fixed by replacing female electrical terminal at Master Switch. Thanks
  7. When I test my annunciator panel at run up (1900 rpms) everything is normal, however if I test it in cruise (2500 rpms) it pops the Annunciator circuit breaker. Has anyone else experienced this? Why do you think this happens?
