|Dead Batteries||Harold Hanhy||12-9-17|
|I have a 2006 Newmar Ventana 3933, I put my RV into storage, I shut everything off and put the "Storage" switch in storage position, I came back in a month to check on my rig and both the House batteries and the RV engine batteries were dead. I'm in a back in Site with rigs on both sides so I can't get to the battery compartment to jump either set of batteries. I read online that you can jump the generator and the charge both sets of batteries. There is no 120v power available to be able to hook up a charger. I opened the generator compartment at the front of my rig and looked for where the cables come from the batteries to the starter on the generator, the only cables that are big enough to be the battery cables are on terminals on the back side on the bottom of the generator, one red, and one black, I followed the black cable and it goes to the chassis, the red cable goes to my front drivers side bin that has my 12v fuses and relays, it attaches to a PC board, and there isn't a big enough cable coming off the PC board to carry the load from my batteries to be the cable to start my generator. I used my car and jumper cables and attached to the terminals that are on the bottom of the generator, no luck. Because of the location and position of my generator, it isn't easy to access the actual inner parts of the unit to see where these cables go. To make matters worse, when I put the rig in storage, the air bags deflated and there isn't much room under rig to crawl around. If I could locate where the starter is, I could just hook up my jumper cables and get the generator going. My next choice is to call Good Sam and hope that they have long enough jumper cables to reach my battery compartment. I am assuming that my RV batteries are used to start my generator and not my House Batteries. I guess in the future, I will remove my battery cables from the terminals to make sure that there is no load drawing power.|

|OK - first - do NOT move the vehicle until the air bags are inflated. Danger is that you'll damage them - if they are not so already! |
If you can access the alternator - the heavy wire on the back of it - is direct to the battery that starts your engine when you normally turn the key to start. Placing a POSITIVE (+) jumper cable on that rear alternator lug will recharge the starting battery - if the battery hasn't frozen while discharged that is.
Low or NO charge batteries will freeze! They are just water/acid and plates of lead or lead alloys. They will not recover and will sometimes explode when they are asked to deliver the amperage necessary to turn the starter.
You've got a quandary here - no room to access anything, deflated air bags, dead batteries - gads! What a problem.
You may have to wait until your neighboring motorhomes leave on vacation to just get to your battery box!
Hopefully my late reply has fallen on your lap long after you've gotten this problem handled. Sorry if that is so.
