The Dynon D180 voltage indication was in the high 13 range, which isn't uncommon. It's usually in the 13.7-14.3 range, and the light has never come on with the engine running before. Is there a failure mode of the AEC 9005 that would cause it to indicate a low voltage so much higher than the intended 13, or should I believe the 9005 and suspect the D180? In all other cases the Dynon indications seem to be about right. The primary alternator is a Plane Power AL12-EI60/C. |
This is difficult to diagnose without
measurements.
All AEC products have lifetime warranty.
If you would priority mail your module
to me, I'll check it on the acceptance test
fixture, evaluate its performance and
return it to you with any necessary
repairs in place.
We don't often get a chance to evaluate
fielded products. I'd be pleased to assist
by checking off at least one box in the
troubleshooting process.
