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 electical system.
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.
Thank you,
