Does anyone have a link (*ahem*, Bill) to some instructions on how to wire up a dual battery system?
I bought a dual battery tray and simply ran + to + and - to - in sequence, but due to experiencing some subsequent problems with this set up I think I may have done this incorrectly.
I don't know a whole lot about electronics so if it has to get way complicated with all kinds of extra fuses and relays and what not, I may give up. But I've already got the second battery and tray so there's some investment there already which I may as well continue with.
I considered simply leaving the batteries un-linked and running the winch and accessories to one battery while the ignition, alternator, etc. ran to the other, but this leaves the obvious problem of how do I recharge the battery that is not hooked up to the motor?
(And yes I know there is an obvious taunt to be made about how a 4500 lb winch doesn't draw much current anyway. Please just pretend we're talking about a 12,500 lb winch ere.)
