Default Re: Practical Use of a Battery Monitor

"The cable on the left of the shunt looks pretty small - inadequate - compared to the other cables being used around the battery. The current traveling through all of them is the same, they should all be the same gauge."

The cable you are referring to (left side of shunt) is the OEM 1 gauge cable, as are all other OEM cables. If it is too small, you know more than the motorhome design engineers. The cable I added (right side of shunt) is 2/0 gauge, two sizes larger. That's what my neighbor/mechanic had available.

Never judge a book by its cover.
