[QUOTE="mikeeg02, post: 1373526, member: 24194"] IF you have to use the frame, you can, but to properly do so you need to take all the paint off, and go down to the bare metal, then use a dielectric grease or something to prevent moisture from getting in between the connector and frame. Then you have to seal the entire connection, to prevent what steel does. Rust. This is typically the source of alternator whine in the stereo. Also uses more lug connectors, which are getting expensive in the 00-0000 range, and is another way to disappoint you in your new battery system down the road. Steel always rusts. Rust is not a very good conductor, and usually requires/causes an arc to make the connection between the lug and the steel. Now limiting your current to what the arc bridged. Using the frame to bridge batteries is a very poor idea in the long term. Especially when the OPs goal is an improved battery system in absolute conditions. When paralleling batteries, it is ALWAYS best to wire them from terminal to terminal with proper size wire to handle the current. [/QUOTE]
