On my structure scan unit I wired the LSS 1 unit as per instructions. Supply to the yellow wire is fused and switched. Supply to the red wire is fused and hot all the time. Everything else from that battery is switched and turned off. If my boat sits for a couple weeks and is not on a charger the battery is drained. I think the LSS 1 is doing it. Is there any reason I can't switch the red wire also??? Thanks for any help given! I know there are a lot of smart people and good advice out there on this site!!!
