My Bluesky solar
controller is showing a -.3amp battery
drain, this is a concern on a steel boat
. I was worried that I had a DC negative leak. This leak could only come from my house batteries
since there is no connectivity with these circuits and the engine
I was hoping someone could confirm my premise that this -.3 amp is an unknown load rather than a leak.
Premise is based on lifting the boat
from the water
there was no sign of electrolysis
(particularly apparent with copper-base anti-fouling); the display was still showing a -.3 amp discharge.
I think the display would show 0.0 amp if it is a leak, as once the boat was removed from the water
there wouldn't be place for the DC negative to leak to. Boat is on isolated stands.
