Noob question: battery tender hook-up? also general ?s re: truck sitting for a year
OK I will soon be picking up the truck listed in my signature below. This is from an estate sale and the truck has been started only intermittently in the last year. I've heard good things about Battery Tenders and I would like to have one for the long term, but I figure I could buy one now and have the current owner put it on the truck to keep the batts charged for when I go to get it.
So please school me a little on the electricals of the PSD. I've owned a diesel Toyota Landcruiser with NATO spec 24v electricals. I assume that the PSD is 12v with the batteries in parallel, not series like my old cruiser. Correct that if I'm wrong. If I'm right, based on the Battery Tender website, I can buy 1 12v battery tender and hook the positive to the positive of one battery, and the negative has to have some kind of wire? between the other battery and the tender to load balance the batteries.
My question is, if I'm a noob instructing a greater noob in how to hook this up (the truck is 4 hours from me), what should I tell them. I think I have to refer to the battery on the driver's side vs. the one on the passenger's side etc. So which battery should get the positive, which the negative, and the wire?
Also, any general other things I should think about for a truck that essentially hasn't really been driven for a year? It's been started, but I'm not sure if it's even gone around the block. My plan is to drive it straight to the Ford dealer and get all the fluids changed as well as a once-over before I drive it 200 miles home.
