This past year I have been having issues with what I had hoped was a faulty ammeter. But after replacing the ammeter with a volt meter as per the recommendation of my local A&P mechanic. I have discovered that the gage was not the problem. I do indeed have a problem in the charging system. With the volt meter, after engine start, it was showing 14volts or more but by the time I got airborne it was only showing 12 or less and after less that a 30 minute flight I had to land because I was down to less that 11 volts. The system just was not charging. This engine only has a little over 100 hours total time on it so I'm wondering if I could have a bad rectifier. In addition to this problem I am getting a noise in the radio ever time I transmit. Could the two be related or is this a separate problem? Opinions please.

I corrected it completely by replacing the rectifier/regulator. Got it from SkyStar.

I am on my 3rd one. I do have an alternator now and it is running parallel to the one that comes with the engine. Mine would act just like yours=2C I believe it is a heat problem. I can now taxi with nav lights=2C landing light=2C strobes=2C tr ansponder=2C 2 radios=2C inst lights and system charges with engine at idle ..
