Solix 10 at front of boat reading 12.2v and Solix 12 at console reading 11.2v or so without motor running. After awhile 12 drops below 11v and 10 remains at 12v. When cranking motor 12 cuts off then back on and 10 stays on.
Finders wired to buss block direct connect to battery. Nothing else to block. Battery is perfect. Any thoughts as why I am getting a volt or more difference?
