This is an intermittent problem. It’s not easily tested by just unplugging the alternator.
Good luck finding your wiring issue - Chris out.
Well I have what’s called a formal education AND experience, not only in electrical engineering, but in pressure transducers.
An alternator would not cause this issue. An unstable alternator output MIGHT show up as unstable readings (I’m not sure if the 12v out from Dynon is filtered in any...
It’s not an alternator issue.
That doesn’t make any sense.
