sounds like it's what i need. i've got a west marine gift card burning a hole from christmas. i do like to raft up or drift with the live well going. never had a problem with two hooked together, but have always liked the idea of a master kill switch.
thanks

It's just nice to know that nothing is going to kill that engine battery, run anything you want til it dies and have the confidence that the main starting battery is good to go.

picked one up today, looks simple to install

LOL ..... Famous last words...... :you::you:

i don't drive a fancy dancy land rover, but i can read them little line drawing pictures on the box with the batteries and the +'s and -'s. why you wanna poop in my chili?

I just use car battery's they come with 5 year warr and are cheaper then marine battery.
I have them on the 1 on or 2 on or all on or all off, my battery's are now on there 6th year with no problems!

Not pooping in your chilly.. Hell, I was thinking about myself as much as anyone else. The term "Looks simple to install" is right up there with "So simple a child can assemble it" that you find on Christmas presents that are half assembled sitting under the tree Christmas morning. I'm sure that you'll have it in and working in no time flat. It was the phrase I was laughing at, not your prowness. Go enjoy your chilli. :beer:

actually i'll just stay at a holiday inn express the night before

And just an FYI...this is the best place for marine wire if you are going to do any rewiring while you're at it.

They do custom lengths for battery cables and heat shrink on connectors for like a buck. Cheapest around and the quality is great. Redid my boat and the neighbors, very satisfied.
