Use butt connectors to add the necessary amount of extension to each cable.Grit dog wrote:
Guy doesn't know what to do and you show him pics of light guage crimp connectors? May as well suggest scotch locks!
HOGWASH! Butt connectors are available for heavy gauge cable and since the cable used on the OP's trailer to wire back from the battery location to the trailer itself is almost sure to be 6 gauge he most certainly can find suitable butt connectors to match this gauge of cable. I've got some 6 gauge butt connectors sitting in my workshop right now I'll be using to extend my own battery cables. Next time when you choose to mock you might want to first know what you're talking about. :S
There are some very good reasons NOT to use Butt connectors on a battery cable:
They create an additional point of water/moisture intrusion into the cable creating corrosion and increasing resistance thus lowering the efficiency of the cable.
It is a "flex" link that will work harden and break with time, especially after being corroded.
Butt Connectors are prone just never recommended for power cables such as batteries and would never pass a Coast Guard inspection if they were in a boat. An RV should be just as well done.
You can do any job half-a$$ed or you can do it right and install a new Marine Cable Battery cable or at the least a new one piece cable.
