I've got a feeling it may be the battery. I have my electronics on a seperate battery from my trolling motor, and the cranking battery only powers the motor and livewell/bilge pumps. I can't remember if I've charged the one the fishfinders are hooked to the last few times out. I'm charging it now and gonna check later. I have the trolling and electronics batteries under the front deck and the cranking in the back. I have an onboard charger in the back, but have to use a portable charger for the two front. I've been putting off getting an onboard for the front, but it looks like I better do it before I kill a couple batteries. Looking at one of the Minnkota dual bank type. I hope that's the case anyway. The console finder has been dead a month or so and I've been saving for a Humminbird SI. If I have to buy two new ones and an onboard, the SI may have to wait. That would suck!
Anyway, hope all the hangovers out there are getting better. Happy New Year to everybody.
