Hi I have a 1992 Safari coach on an oshkosh chassis, 8.3 cummins diesel pusher, unit is from a family estate, and has not run for 18 month. Batteries froze and the late owner threw them out. My question is what type of batteries are for starting 12 volt X 2 or 6 volt X 2 in series. There are two black and two red leads. also the coach batteries are also missing. the tray in which they sat has room for 3 there are two red leads and one black lead. I tried hooking up the chassis batteries with two new 950 cc batteries black to neg and red to positive and the coach batteries I used two 12 volt put red leads on positive and black lead on one of the batteries and used a short jumper to connect to the other neg on the other battery. There was no power to the starting circiut at all. Is there another way I should be hooking up the batteries, or if not is there another power switch other than the coach switch in the stair well or some sort of breaker system that might have blown when the batteries froze. There is also another battery somewhere in the coach which powers the starter for the gen as well as some internal items after 5 hours of looking for that one I gave up.
