Thanks for the help so far I am fixing to start checking. The other day, I left everything off while fishing. No graphs, and I didnt even run livewells until big motor was started. The few times I got to start the big motor, we only ran a few hundred yards, so I dont know if it allowed it to charge battery any further. Also, when starting battery went dead, I switched to the TM battery and it cranked right up. There was still a noticable pull down in battery power when I turned the key, but it started right up.
