Engine will not crank, even with ignition hand button.

Dropped in another A4 into my boat. 2 battery system, brand new batteries. Perko 1,2,both switch, link 10 monitor on a shunt, and a solid state isolator. It's a simple 2 battery system that I think I have my head wrapped around. Problem is the ignition switch does nothing. To troubleshoot this I got a push button ignition switch and attached it to the correct terminals. I heard a very faint clicking noise in the solenoid but it barely reacted to getting power. Seemed like it wasnt getting much power at all... scratching my head big time on this one. I'll draw up a schematic on the system and post it later.
