Went out to the CC this morning, started it up no problem, half way thru climb-out the battery voltage went into the yellow, 12.5V, by the time I got turned around and landed it was 11.9V. My amp gauge on my dynon showed no charging amps on my way back to the airport and after landing, however it was charging at the time of take-off. Checked the battery itself and it was showing 12.4V. I've got 110 hours on the CC, has anyone one seen issues with their alternator on their CC?
