PA38 low voltage light
The saga started 4 months ago with a new alternator.
Low voltage light began to flicker on and off. Ammeter was still reading normally
Regulator was replaced no change.
On the last annual low voltage light was replaced and new battery was installed (non gel)
Now the bloody thing is on all the time.
At all times the Ammeter shows current, jumps up etc if the nav lights are turned on. No dead bat episodes in the morning or radios dropping out etc.
Anyone else experenced this?
I haven't a clue how a low voltage system is set up.
Is it a wheatstone bridge and we need to tune it for zero difference?.
I might add its on a Public CoA and the engineers that look after it give sterling service. But they are flumouxed as well.
