Keeping my Battery's Charged.

[Carmen]

I remember reading a while back how someone hooked up a battery tender to their stock M37 24 Volt system. They mounted the unit near the dual batterys so as not to have to remove it everytime. Can anyone help me. I would like to also do the same thing.

Thanks
