Greetings Folks,
I seem to have some sort of charging issue with my RV-6A. It has a 35a Denso alternator which appears to be making power as the voltage on the Dynon SkyView reads 14 - 14.1. However, the Dynon also indicates a drain of -1 to -3 amps. I thought perhaps it was the battery so I replaced it (new Odyssey 680) but it did not appear to help.
This morning I did a test. Charged up the Odyssey to full using a 2 amp charger. Flew for ~40 minutes, with the Dynon indicating -3 throughout the flight. After landing I put the battery back on the charger and waited. After 30 minutes it was still not showing full.
My first guess would be the alternator, but it's putting out the right voltage. It has an integrated regulator so I can't point the finger at the reg. Anyone have a guess what this might be? Is it possible for an alternator to fail in some weird way that it can make rated voltage but not push enough amperage to both run the systems and charge the battery?
Thanks!
Steve
