Title: Kit of Battery Cables??
Post by: Mike Wild on March 25, 2017, 11:45:35 PM

Another of my goofy questions: I want to replace all of the cables that connect my batteries in parallel. 2000 Marquis Amethyst with the 6 house and 2 chassis set up. Googled around and couldn't find a source for a set of cables. Does such a thing exist?

Thanks for your thoughts.

Mike

Mike,
There may be but I'm not aware of any source for them. I've made them up myself when I've needed a new one.

Mike,
No one will have a kit containing all the cables you need because there too many variables in battery bank configuration in motorhomes to make selling a kit practical. However, most large auto parts stores that deal with heavy duty truck or marine applications will make cables to your specifications or you can do like Steve and make your own.

First question: why do you want to replace all your cables? Are they corroded? Like Gerald stated you will have to have a shop make them up or do them yourself.

      Hi Guys,
  Having the same issue on my own coach. The lugs the manufacturer used when fabricating the cables used "open" end lugs which exposes the cable ends to corrosion. Over time the corrosion migrates up into the copper strands inside the insulation. Cleaning the connections does not fix this condition. Undo resistance from this condition raises havoc with the inverter/converter which mis-interprets the true state of charge and battery condition. The original big black Freedom 20 charger was notorious for boiling batteries because of dirty battery terminals.
     When replacing the lugs, use "close ended" cable terminals. Before installing the terminals, slide a piece of heavy duty heat shrink tubing over the cable then crimp the lug. Position the heat shrink over the shank of the lug then use a heat gun or torch to seal the lug to the cable. Corrosion is limited to the connection only. Use anti-corrosion felt pads under the terminals and the red sealant spray on terminals. Hope this helps, Fred
