[QUOTE="BCotrell, post: 8678932, member: 666314"] I just dealt with challenges stemming from my chassis not being a good ground (rubber engine mounts,etc) so If you don’t have a complete loop that includes a good chassis to frame ground your second battery voltage could (may not but could) suffer if you’re only running positive battery to battery. My remedy was front battery to frame ground and front battery to rear battery ground. Second battery to frame would be essentially the same as long as you already have solid front ground to frame. Cost me $20 run of 2/0 welding battery to battery and two extra lugs. [/QUOTE]
