Hi, I want to move the battery to the trunk in my 64 cuda.How big of a positive lead do i need to run. I hear tell the negative can just be grounded thru the frame. I have a long lead i cut off from an old Lincoln 220v Arc welder. I would really like to use it , considering the price of copper nowadays. It has about twice the diameter of a regular positive lead. i would just need to solder some ends on it. neal zimmerman, eugene oregon
