Starter Batteries

Does anyone have any kind of schematic showing where the cables(wires) go in hooking up the starter batteries on a 1999 National Tradewinds. Had batteries replaced and now he isn't quite sure where all the wires go properly. I know they should have been tagged as they were removed but that didn't happen so now need help. Thanks
  • how meney wires we talking? 24v or 12v system? you might get a meter and start tracing each one.

    I doubt anyone is likely to have a schematic showing the battery wiring on a 1999 RV, and even if they did, it is likely to have been changed in 23 years. 12v batteries or 6v batteries? 12v system or 24v system? 1 chassis battery or 2? 1 house battery or 2? Maybe a pic or 2 of what you are looking at could help us.

    You will need to follow the large battery cables out to see where they go. The starter battery POS goes to the starter. The house battery POS will head for the power center distribution panel. The NEG of both should go to the chassis somewhere, either separate locations or possibly the same location. Keep in mind that I have little to no experience with DPs, so I may be way off here. Again, pic(s) could help us help you, but you will need to follow the cables.
  • IMHO they have not changes over the years so I would go find another unit and see how it is wired.

  • Thanks for the info. I was really hoping someone with the same unit could shoot me a picture of the way their unit was wired. There are two batteries that provide 12 volts to start the 300 HP Cat engine. Right now, when i turn the key I have no response to the engine, so I am sure one of the accessory wires is not properly connected.
